News and Updates on Volcanoes and Earthquakes

The Vanuatu Meteorology and Geohazards Department (VMGD) reported that seismic data confirmed continuing unrest at Lopevi during September. Low-level thermal anomalies were identified in satellite images during 12-13 and 17 September. Small fumarolic steam plumes were continuously emitted from the summit crater on 22 September based on webcam images. ... Διαβάστε όλα

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that an eruption at Lewotolok was ongoing during 24-30 September. On most days white-and-gray ash plumes rose 100-600 m above the summit of the cone and drifted W and NW; only white plumes rising to 100 m above the summit were observed on 27 September. Several nighttime webcam images showed Strombolian ejections of incandescent material above the cone and onto the flanks. ... Διαβάστε όλα

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that daily white-and-gray or gray ash plumes with variable densities rose as high as 2 km above the summit of Lewotobi Laki-laki and drifted N, NW, W, and SW during 23-29 September. According to a news article the Fransiskus Xaverius Seda Airport (60 km W) was closed on 26 September through early 27 September; volcanic ash caused six flights to be canceled. PVMBG noted that seismic activity during the week was dominated by low-frequency earthquakes, non-harmonic tremor, and signals indicating eruptive events and emissions. ... Διαβάστε όλα

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that the eruption at Krasheninnikov continued during 18-25 September. A daily large thermal anomaly over the volcano was identified in satellite images. Explosions at Northern Cone produced ash plumes that rose 2.4 km a.s.l., or nearly 600 m above the summit, and drifted 260 km SE and E during 23-25 September. ... Διαβάστε όλα

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that wind was no longer resuspending ash previously deposited on the N flank of Klyuchevskoy. Only fumarolic emissions were observed. The Aviation Color Code was lowered to Green (the lowest level on a four-color scale) on 25 September. ... Διαβάστε όλα

The Hawaiian Volcano Observatory (HVO) reported that the eruption within Kilauea's Kaluapele summit caldera, characterized by episodic fountaining, incandescence, and intermittent spatter from craters along the SW margin of Halema'uma'u Crater, continued at variable levels during 23-29 September. Incandescence at both the N and S vents was visible overnight during the week and gas plumes continued to be emitted from them. Scientists did not see lava in the vents during an overflight on 24 September. ... Διαβάστε όλα

The Alaska Volcano Observatory (AVO) reported that on 27 September strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes dispersed unconsolidated ash up to 1.8 km (6,000 ft) a.s.l. to the SE. The ash was originally deposited during the Novarupta-Katmai eruption in 1912. ... Διαβάστε όλα

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that explosions at Karymsky were last observed in August. In September activity was at moderate levels characterized by steam-and-gas emissions and a weak thermal anomaly identified in satellite images; weather clouds sometimes obscured views. On 25 September the Aviation Color Code was lowered to Yellow (the second level on a four-color scale). ... Διαβάστε όλα

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that the eruption at Ibu continued during 24-30 September. Dense gray or white-and-gray ash plumes rose 300-700 m above the summit and drifted in multiple directions. Incandescence at the summit was visible in a few nighttime webcam images. ... Διαβάστε όλα

The Alaska Volcano Observatory (AVO) reported that slow lava effusion continued to feed a thick flow in Great Sitkin's summit crater during 24-29 September. Satellite data indicated that the SE part of the flow slightly inflated. Advancement was detected around the SW, S, and SE margins of the flow; the fastest moving part of the flow advanced at a rate of about 5 m per day. ... Διαβάστε όλα
