The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that Raung continued to erupt during 18-25 June. Seismicity during 16-18 June fluctuated but increased overall. A thermal anomaly on the crater floor was identified in a satellite image on 18 June. ... Alles lesen

The Observatorio Vulcanológico y Sismológico de Costa Rica-Universidad Nacional (OVSICORI-UNA) reported continuing gas-and-steam emissions with occasional minor amounts of ash at Poás during 18-24 June. Significant amounts of gas-and-steam emissions continued to be emitted, particularly from Boca A. On 18 June sulfur dioxide emissions averaged 273 tons per day (t/d), though they were as high as 1,500 t/d towards the second half of the week; overall, though levels remained high, there has beenwas a decreasing trend in sulfur dioxide emissions during over the previous few weeks, though levels remained high. ...

The Servicio Geológico Colombiano's (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that eruptive activity at Nevado del Ruiz continued during 17-23 June, though weather conditions often obscured visual observations. Seismic data indicated that events associated with fluid movement decreased in both number and intensity compared to the previous week. Seismicity associated with rock fracturing decreased in number but increased in intensity compared to the previous week. ... Alles lesen

The Balai Penyelidikan dan Pengembangan Teknologi Kebencanaan Geologi (BPPTKG) reported that the eruption at Merapi (on Java) continued during 13-19 June. Seismicity was less intense than the previous week. The SW lava dome produced 26 lava avalanches that traveled as far as 1.9 km SW down the Bebeng drainage, 20 that traveled as far as 2 km SW down the Krasak drainage, and 56 that traveled as far as 1.9 km W down the Sat/Putih drainage. ...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that an eruption at Lewotolok was ongoing during 18-24 June. Daily gray, white-to-gray, or gray-to-black ash plumes rose 400-900 m above the summit of the cone and drifted NW, W, and SW. Clear nighttime webcam images showed incandescent material both at the summit cone and being ejected above the cone. ... Alles lesen

The Servicio Nacional de Geología y Minería (SERNAGEOMIN) reported declining seismicity, low sulfur dioxide emissions, and no deformation at Láscar in recent weeks. During 1-15 June sulfur dioxide emissions measured at a station 6 km ESE averaged 1,254 tonnes per day (t/d) with a maximum value of 2,572 t/d on 12 June. No anomalous emissions were detected in satellite data. ... Alles lesen

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that a bright thermal anomaly at Klyuchevskoy was identified in satellite images during 13-19 June. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). Dates are based on UTC times; specific events are in local time where noted. ... Alles lesen

The Hawaiian Volcano Observatory (HVO) reported that the eruption within Kilauea's Kaluapele summit caldera, characterized by episodic fountaining and intermittent spatter at two vents along the SW margin of Halema'uma'u Crater, continued at variable levels during 18-24 June. Nighttime incandescence at both the N and S vents and intermittent lava spattering at the N vent were visible during 18-19 June. Small, sporadic periods of spattering and intermittent overflows of lava began at the N vent at 2326 on 19 June. ... Alles lesen

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that moderate activity continued at Karymsky during 13-19 June. A thermal anomaly over the volcano was identified in satellite images during 17-18 June; the volcano was quiet or weather conditions prevented views on the other days of the week. The Aviation Color Code remained at Orange (the third level on a four-color scale). ... Alles lesen
