More than 500 people have been evacuated from the the tiny volcanic island after the eruption began without warning on Friday January 5. This earthquake had no apparent affect on the volcano at the time. McKee; 13-14 November, C.O. Synonyms of features appear indented below the primary name. The MIROVA project recorded thermal anomalies from Kadovar in early January and early March 2018 (figure 16). Photo: NZ Airforce. Around 1,500 residents of Kadovar Island … the S coast, which may have been a small hydrothermal eruption or, more likely, a vigorous ebullition of gas bubbles. However, the event will continue to be treated as a possible precursor to an eruption, and the former inhabitants will be advised to maintain the evacuation for the present. The lava flow grew outward from the shore for tens of meters before collapsing in early February, but it reappeared a few days later. Satellite data. Activity during January-April 2019. Based on satellite and wind model data, the Darwin VAAC reported that on 30 July an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. During 14-22 February continuous plumes of white vapor rose from both Main Crater and SE Coastal Vent, punctuated by dense ash emissions from both areas during 16 and 20-22 February and occasional booming noises. and drifted NW. 2018: January During a flyover on 13 January, RVO noted variable steam and gas emissions rising to 1 km above the Main Crater and identified five distinct vents (figure 14). However, another area of thermal activity (high on the E side of the lava dome) had produced a significant vegetation kill in the past few months. The youthful island lacks fringing or offshore reefs. The Darwin VAAC reported the plume drifting WNW extending about 185 km on 8 January. All residents of Kadovar have been evacuated to Blupblup Island. From the NW side of the summit crater rim, Jung saw the actively growing dome on the side of a larger dome, and steam and gas issuing from the growing dome (figure 52). A dormant volcano that first began erupting on January 5 exploded on Friday, forcing the evacuation of hundreds of people from the Kadovar island in … A sulfur odor was noticed by residents on Blup Blup (15 km N) on 16 and 22 February. An elongate area extending from the summit area to the E-flank coastal dome appears lighter in color in a 7 September Sentinel-2 natural color satellite image, and as a higher temperature area in the correlating thermal bands, indicating a hot avalanche deposit. Strong sulfur dioxide emissions were detected. By the end of the first week of March 2018 the flow was about 17 m above sea level; its growth rate had slowed, adding only one meter by late March. An incandescent lava flow slowly extruded from the SE Coastal Vent. The Darwin VAAC reported intermittent ash plumes rising to 2.7 km altitude and drifting W on 1 October 2018. In a 12 February report RVO noted that activity from Main Crater consisted of white plumes rising 20 m and drifting a few kilometers SE and weak nighttime crater incandescence. and drifted SE and E. Based on satellite data and wind model data, the Darwin VAAC reported that on 9 April an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. While the ash plume erupted near-vertically above the island, a more diffuse gas plume rose from multiple vents on the summit dome and dispersed at a lower altitude. and drifted SE. A possible lava dome was at the base of the plumes but showed no evidence of incandescence. For the following three days ash drifted SW, W, then NW at 2.1 km altitude, finally dissipating on 1 November; the thermal anomaly at the summit was large and intense in satellite images on 27 October and 1 November compared with previous images (figure 27). In a 12 February report, RVO noted that activity from Main Crater consisted of white plumes rising 20 m and drifting a few kilometers SE accompanied by weak nighttime crater incandescence. Uru in Yangoru (130 km W), and Woginara (140 km W), along with locations along the W coast of the Wewak District. The gray plumes rose less than 360 m above the vent and drifted SE. The Southern Coastal Vent, located where the original fractures entered the sea, was inactive. Large amounts of sulfur dioxide had been detected since 8 January, and continued to be emitted. The Kadovar Island volcano, which is approximately 24 kilometers north of the Papuan mainland, began erupting on January 5. During April, pulsating steam plumes rose from two vents at the summit, and thermal anomalies appeared at both vents in satellite data (figure 48). Click on the index link or scroll down to read the reports. and drifted W. An ash plume was visible in satellite images on 3 October drifting W at an altitude of 2.1 km (6,900 ft) a.s.l. | December The original fumarole of last September shows the same degree of activity as it did then. Similar activity was frequently seen during clear weather in the following months. On clear days the plume was sometimes visible from Wewak, on the mainland 100 km W. Additional vents produced variable amounts of steam. and drifted NW. In some cases additional feature type, elevation, or location details are provided.

A short-lived ash emission rose to 2.4 km altitude on 11 January 2019 and drifted E; it dissipated the next day. The Rabaul Volcanological Observatory in Papua New Guinea says the eruption of Kadovar Island remains dynamic. Sources: Rabaul Volcano Observatory (RVO); BBC News; Brandon Buser. Cooke R J S, Johnson R W, 1978. Silver E, Day S, Ward S, Hoffmann G, Llanes P, Driscoll N, Appelgate B, Saunders S, 2009. Kadovar is a volcanic island in Papua New Guinea north-east of the much larger island of New Guinea. MODVOLC thermal alerts were issued on three days; 15 and 22 January, and 7 February 2018. The volcano erupted in January 2018 and the eruption is ongoing as of 2020. Two summit vents remained active throughout May and June 2020, producing pulsating steam plumes that were visible for tens of kilometers and thermal anomalies visible in satellite data (figure 50). According to Brandon Buser, just after eruption plumes started rising from a vent on the SE side of Kadovar on 5 January boats from a village on the mainland (22 km SW) and from Bam (25 km E) were sent to the island to evacuate residents. October 1976. Continuous ash emissions rising to 1.8 km altitude were reported by the Darwin VAAC beginning on 9 November 2018 moving WNW and lasting about 24 hours. In their report on 2 February 2018, RVO noted that the lava flow continued to grow. Another ash plume identified by a pilot and in satellite images rose to an altitude of 1.8 km on 20 June and drifted W. An ash plume was visible in satellite images on 28 September drifting SE at an altitude of 2.1 km. A new steam plume on the eastern slope appeared in a 22 September 2018 image (figure 25). On 15 May an ash plume originated from two vents at the summit area and dispersed to the east. A trip to Kadovar by tourists in mid-May 2018 provided close-up views of the dense steam plumes at the summit and the growing E-flank coastal dome (figures 20 and 21). RVO reported that the eruption at Kadovar continued during 23-24 January at levels similar to the previous few days. A few volcano-seismic events were recorded in both November and December, but such events appeared to be absent in February. Sentinel-2 thermal images showed elevated temperatures through to the end of December but at a lower intensity than previous months. All vegetation in the area had been killed. Gas-and-steam plumes were persistent in every Sentinel-2 and NASA Suomi NPP / VIIRS (Visible Infrared Imaging Radiometer Suite) image. A dormant volcano that first began erupting on January 5 exploded on Friday, forcing the evacuation of hundreds of people from the Kadovar island in Papua New Guinea. Similar activity continued through July with gas-and-steam emissions visible in every cloud-free satellite image. Sulfur dioxide emissions and seismicity had both decreased. No volcano-seismic activity was recorded during 5.5 hours with a portable seismograph. They also noted that the influence of the sea breeze was also spreading minor ash to the SW. Lowenstein P L, 1982. By the last week of January, the ash plumes were only rising about 100 m above the Main Crater and drifting W; weak incandescence was still observed at night. A brief ash emission was reported on 21 October 2018 at 2.4 km altitude drifting NE for a few hours. The dormant volcano erupted in spectacular fashion over the weekend, spewing lava for the first time in known history and sending an ash cloud 2.1 kilometres above sea level. The Australian government is contributing 25,000 Australian dollars (nearly $20,000) in humanitarian supplies to Papua New Guinea, Australian foreign minister Julie Bishop wrote in a tweet. | November. Visitor observations on 21 October 2019. Thermal anomalies and emissions continued through to the end of 2019 (figure 41). Activity during October-December 2018. More than 500 people were evacuated as a result. ... An earthquake of magnitude 4.2 occurred only 13 minutes ago 79 km northeast of Sorong, Indonesia, Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG) reported. 2020: January It was estimated that 50 or 60% of the island was covered in volcanic debris, which appeared to be primarily ash along with some pyroclastic flows. RVO reported minor eruptive activity at Kadovar during 1-15 July consisting of occasional light gray ash plumes of variable densities rising a few hundred meters above the summit crater. RVO stated that during 7-8 January ash continued to be emitted, and blown tens of kilometers WNW. The main body of the flow significantly bulged upwards, with a distinct 'valley' visible between the bulge and the island's flank. and drifted SW, S, and SE. Information Contacts: Hawai'i Institute of Geophysics and Planetology (HIGP) - MODVOLC Thermal Alerts System, School of Ocean and Earth Science and Technology (SOEST), Univ. Information was provided by the Rabaul Volcano Observatory (RVO), the Darwin Volcanic Ash Advisory Center (VAAC), satellite sources, and photos from visiting tourists. MODVOLC thermal alerts were issued on 4 and 9 June. A dormant volcano that first began erupting on January 5 exploded on Friday, forcing the evacuation of hundreds of people from the Kadovar island in Papua New Guinea. Kadovar volcano is an island located 25km north of the entrance to the Sepik River, Papua New Guinea. Weak earth tremors were felt, apparently during the preceding few days, and an explosive sound was heard. The growth rate slowed later in the month, and only one meter of change was observed between 10 and 20 March. Dates and personnel were: 18-19 August, V.F. A dormant volcano on Kadovar Island, northeast of Papua New Guinea, has erupted for the first time in known history, with a large plume of ash rising 2.1km above sea level, forcing the evacuation of over 500 residents. Maximum temperatures have been steady at 99-100°C, marked expansion of the main thermal area has ceased (although weak isolated gas vents are still occasionally found in new areas), and the quantity of gas emitted may even have declined slightly. The volcano, on Kadovar Island northeast of Papua New Guinea, lay dormant until January 5 when it began to erupt at around noon, local media reports. At least 1,500 residents had been evacuated on Sunday and were brought to the Papuan mainland, about 15 miles from the Kadovar island. "Although the initiation and early rapid development of this thermal activity led to the belief in a forthcoming Kadovar eruption, the stabilization (or even slight decline) in activity suggests the possibility that the event may be confined to thermal activity. The Darwin VAAC reported continuous ash emissions beginning on 13 March 2020 that rose to 1.5 km altitude and drifted SE. McKee and D. Norris. Ash emissions were reported by the Darwin VAAC and photographed by tourists during June (figure 23) and September 2018 (BGVN 43:10), but thermal activity appeared to decline during that period (figure 24). The volcano's first confirmed eruption … The Darwin VAAC stated that on 6 February an ash plume rose to 2.1 km (7,000 ft) a.s.l. Kadovar Island is volcanic island situated south-east of Wewak, East Sepik Province in Papua New Guinea. Volcanoes and volcanology in Papua New Guinea. There is no Emissions History data available for Kadovar. Dent; 30 September, C.O. A seismic event counter was installed on the island. The maximum ground temperature in the S coast discolored zone was 49.5°C, similar to September. Papua New Guinea volcano latest: Is Mount Kadovar erupting? and drifted NW and W. RVO reported quiet conditions at Kadovar during 1-20 September with only diffuse white plumes rising from the volcano. The remote Kadovar Island volcano became active on 5 January 2018 with mild volcanic activity on the south-eastern side of the island. Collections of fumarole gas were made in evacuated glass tubes containing silica gel, and gas condensates were also collected. A PAPUA New Guinea volcano has rumbled to life after many years dormant and hundreds of people have been evacuated. The volcano on the northern island of Kadovar, more than 500 metres (1,640-feet) high, erupted on Friday, the Darwin Volcanic Ash Advisory Centre told AFP. The first confirmed historical activity began in January 2018 and resulted in the evacuation of residents from the island. The first signs were noted May 1976 from an area at the S coast where possibly a small hydrothermal eruption or, more likely, a vigorous emission of gas bubbles occurred. A new lobe 20-30 m long grew out from the seaward side of the dome boundary, channeled by levees which had developed on the sides of the dome. It is intended to continue regular inspection visits to the volcano, but a full-time observation post is not planned at this time. Based on satellite data and wind model data, the Darwin VAAC reported that during 10-12 October ash plumes from Kadovar rose to an altitude of 2.4 km (8,000 ft) a.s.l. The steeply sloped 1.4-km-diameter Kadovar Island is located in the Bismark Sea offshore from the mainland of Papua New Guinea about 25 km NNE from the mouth of the Sepik River. | July A lava flow on the E flank extended outward from the island, extruding from a vent low on the E flank and forming a dome just offshore. • Study of the first historical confirmed eruption at Kadovar Volcano, a small volcanic island north of Papua New Guinea. Shiveluch volcano, Russia It was estimated that up to 60% of the island was covered in volcanic products, which primarily appeared to be ash along with some pyroclastic flows. The reported hot ground on the mid-slope of the dome was about 30 m x 15 m in area, and was producing vigorous emissions of SO2 and HCl gases (indicated by Dräger tubes) from one main vent and numerous minor vents, at temperatures up to 99.7°C. Sources: Rabaul Volcano Observatory (RVO); Darwin Volcanic Ash Advisory Centre (VAAC). Both discrete eruptions and continuous ongoing activity was seen in satellite imagery through 9 January, with the plume visible at distances of over 200 km W and WNW. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. | February Intermittent discrete emissions of ash continued daily at that altitude through 16 October, drifting NW or W. Ash emissions drifting NW and thermal anomalies at the summit were visible in satellite imagery on 2 and 12 October (figure 26). and drifted SE. A 1700 report of smoke seen briefly there was believed at the time to be a volcanic eruption. Thick lava flows with columnar jointing forms low cliffs along the coast. Bright incandescence from both the Main Crater and the SE Coastal vent was visible on 14 March, coincident with the start of dark gray ash emissions from both vents, lasting until 19 March. Ash and steam emissions from Kadovar were first reported on 5 January 2018. Photo : Tsuda — Flickr: Kuchino-erabu island (volcano), CC BY-SA 2.0, https://commons.wikimedia. The Darwin VAAC issued a sequence of ash advisories starting on 5 January that noted ash moving W at an altitude of about 2.1 km (7,000 ft) a.s.l., and set the Aviation Color Code to Orange. Activity during January-June 2020.

Intense incandescence from Main Crater, the SE coastal vent, and other areas was visible. Felt earthquakes were noted by inhabitants of nearby islands on several occasions, but there is no strong reason to associate these with Kadovar volcano. The waves were reported at 1050, before the main collapse of the dome. On 1 October an ash plume rose to 2.7 km (9,000 ft) a.s.l. This prompted authorities to evacuate the 590 occupants of the island. RVO reported that emissions from Kadovar’s Main Crater were white from 1 March, until an explosion on 1800 on 5 March was followed by gray emissions through 8 March. Kadovar is an island volcano north of Papua New Guinea and northwest of Manam. | February Another shipboard tourist photographed an ash plume on 18 November rising a few hundred meters above the summit (figure 30). Fuego Volcano Volcanic Ash Advisory: VA NOT SEEN IN STLT. Sentinel-2 satellite data confirmed thermal anomalies at the summit on 5 and 25 January 2020, and an ash emission on 20 January (figure 46). RVO reported that on 9 February the lava flow at the SE Coastal Vent had collapsed, causing 5-6 minor tsunamis less than 1 m high that were observed by residents on Blup Blup's E and W coasts. A month later on 5 April the anomaly was nearly as strong and a dense ash and steam plume drifted N from the summit (figure 34).

Elevated temperatures were detected in Sentinel-2 thermal satellite data on 20, 21, and 30 May (figure 38), with accompanying gas-and-steam plumes dispersing to the NNW and NW. Based on satellite data and wind model data, the Darwin VAAC reported that during 27-28 November ash plumes from Kadovar rose to an altitude of 0.9 km (3,000 ft) a.s.l. Kadovar is also a Holocene stratovolcano with a suspected (but not confirmed) eruption in 1700. After the first recorded explosions with ash plumes in early January 2018, intermittent ash plumes continued through March 2018. Nighttime incandescence was noted from both Main Crater and the SE vent. Based on satellite data, the Darwin VAAC reported that during 21-22 September ash plumes from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. "The main thermal area has been little changed during this period. The previously dormant volcano, more than 500 metres (1,640 feet) high, on the northern island of Kadovar off PNG erupted on January 5 with all 600 residents evacuated. Dormant volcano Kadovar wakes with first eruption in known history 7 Jan, 2018 06:13 PM 2 minutes to read The once dormant Kadovar volcano awakens in its first eruption in known history. | June Activity increased on 21 September and remained elevated at least through 26 September, the date the last visual observation was received by RVO. During their return trip from Bam on 8 January 2018, the missionaries again circled the island and noted that the eruption seemed to be occurring from different vents. Our expert volcanologists and photographers offer unique travel experiences: Just 9 minutes ago, a 4.5-magnitude earthquake struck near Calingasta, Departamento de Calingasta, San Juan, Argentina. "Volcanologists have made three detailed investigations at Kadovar since the report in July. Pulsating steam plumes, thermal anomalies, and periodic ash emissions continued throughout 2019 (BGVN 44:05, 45:01), and from January-June 2020, the period covered in this report. Although initial news reports regarding the population and evacuation status were unclear, the East Sepik Governor, Allan Bird, told media on 8 January that 591 residents of Kadovar had been evacuated to Blup Blup island (about 10 km N) due to the organizational efforts of village councilors on the two islands. During the period if increased activity dense dark gray and brown ash plumes rose several hundred meters above the summit crater (700-800 m) and drifted NW. At 1830 on 1 February a collapse of the N part of the dome produced a gray plume, vigorous steaming at the collapse site, and nighttime incandescence. Its rim drops steeply into the sea. Kadovar is a 365-m-high, 1.4 km-diameter volcanic island. Ash emissions were generally continuous at altitudes from 2.4 to 3 km, although low level emissions of primarily steam and gas were observed on 20 January that included intermittent phases of increased ash content. There are no samples for Kadovar in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection. There is no Deformation History data available for Kadovar. The island is completely vegetated, and supported a village of more than 300 people built around the crater rim. Based on satellite data and wind model data, the Darwin VAAC reported that on 19 August an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. A new ash plume clearly identifiable on satellite imagery appeared on 13 November at 2.4 km altitude moving E, again visible for about 24 hours. Information about the eruption is provided by the Rabaul Volcano Observatory (RVO), the Darwin Volcanic Ash Advisory Center (VAAC), satellite sources, news reports, and local observers. A brief emission to 3.7 km was also noted that day. According to the International Federation of Red Cross and Red Crescent Societies (IFRC), the entire population of Kadovar, about 600 people who lived on the N side of the island, was relocated to nearby Blup Blup Island which is home to about 800 residents. A MODVOLC thermal alert was also issued on this day, and again on 17 May. The first confirmed historical eruption at Kadovar began around mid-day local time on 5 January, according to witnesses. Five newly-named vents were observed during an overflight conducted on 13 January: Main Crater, Western vent, and Southern vent (all three are at the summit), the SE Coastal vent, and the Southern Coastal vent. The maps shown below have been scanned from the GVP map archives and include the volcano on this page. The styles of volcanic eruption mainly depend on the viscosity and the amount of gas in the magma material. On each occasion, temperatures were measured, gases and gas condensates were collected, and seismic recording was carried out; a magnetic resurvey was made during the most recent inspection. Maximum temperatures were still 99-100°C but there may have been slight changes in the magnetic field pattern. Ash plumes rose 370 m above the island and drifted SE, though on 22 February the winds blew the plumes N and NW. Its first confirmed observed eruption began in early January 2018, with ash plumes and lava extrusion resulting in the evacuation of around 600 residents from the N side of the island (BGVN 43:03).
