Kirishimayama (Japan) - Report for 11 October-17 October 2017 - NEW

Actividad volcánica (SI/USGS) - Mié, 2017/10/18 - 08:30

JMA reported that an eruption at Shinmoedake (Shinmoe peak), a stratovolcano of the Kirishimayama volcano group, began at 0534 on 11 October, prompting the agency to raise the Alert Level to 3 (on a scale of 1-5). Ash plumes rose 300 m above the crater rim (2 km a.s.l.) and drifted NE, though some news sources stated that plumes rose 2 km above the crater rim. Volcanic-tremor amplitude increased and inflation was detected. Ashfall was noted in at least four towns in the Miyazaki and Kagoshima prefectures. On 12 October ash plumes rose as high as 2 km. Based on JMA notices, pilot observations, and satellite data, the Tokyo VAAC reported that ash plumes rose 1.8-2.1 (6,000-7,000 ft) a.s.l. on 11 October and 3.4 km (11,000 ft) a.s.l. on 12 October. Gas measurements taken during field surveys on 12 and 13 October showed that the sulfur dioxide flux was 1,400 tons/day, an increase from 800 tons/day measured on 11 October. Volcanic tremor fluctuated but the amplitude was slightly lower. During 0823-1420 on 14 October an event produced a tall plume which rose 2.3 km above the crater rim. Another event, at 1505, generated a grayish-white plume that rose 1 km and then blended into the weather clouds. Ashfall was reported in Kirishima and Sono in the Kagoshima prefecture, and from Kobayashi in the Miyazaki prefecture to Hyuga city. An event was detected at 1300 on 15 October, and an increase in low-frequency earthquakes was recorded on 16 October.

Sarychev Peak (Russia) - Report for 11 October-17 October 2017 - NEW

Actividad volcánica (SI/USGS) - Mié, 2017/10/18 - 08:30

A NOAA/NESDIS scientist noted that a thermal anomaly at Sarychev Peak was identified in satellite images on 12 October. Robust thermal anomalies were identified on 14 October, and were accompanied by a plume of unknown composition. Thermal anomalies were also recorded by the MODVOLC and MIROVA thermal detection systems.

Nevados de Chillan (Chile) - Report for 11 October-17 October 2017

Actividad volcánica (SI/USGS) - Mié, 2017/10/18 - 08:30

Servicio Nacional de Geología and Minería (SERNAGEOMIN) Observatorio Volcanológico de Los Andes del Sur (OVDAS) reported that a series of six pulsating gas-and-tephra emissions from low-energy explosions began at 0843 on 11 October. The plumes rose 1 km and drifted SW. The Alert Level remained at Yellow, the middle level on a three-color scale, and the public was reminded not to approach the craters within a 3-km radius.

Santa Maria (Guatemala) - Report for 11 October-17 October 2017

Actividad volcánica (SI/USGS) - Mié, 2017/10/18 - 08:30

INSIVUMEH reported that on 11 October a moderate lahar descended the Cabello de Ángel and the Nimá I drainages, both tributaries of the Salama river. During 12-13 October ash plumes generated by explosions rose 500 m above the crater rim and drifted SE, causing ashfall in Finca San José. Avalanches of material descended the SE part of the lava dome. On 13 October the seismic network detected moderate-to-strong lahars in the Cabello de Ángel and the Nimá I drainages triggered by heavy rain. Explosions during 13-14 October produced ash plumes that drifted SW, causing ashfall in La Florida (5 km S) ranch. Ash plumes from explosions detected during 15-16 October rose 600 m and drifted S. Ash fell locally around the volcano. Avalanches of material descended the NE and SE parts of the lava dome.

Ambrym (Vanuatu) - Report for 11 October-17 October 2017 - NEW

Actividad volcánica (SI/USGS) - Mié, 2017/10/18 - 08:30

The Vanuatu Geohazards Observatory (VGO) reported that aerial observations of Ambrym on 24 and 30 September, and 1 and 6 October, and the analysis of seismic data, confirmed that minor eruptive activity within the caldera was characterized by hot volcanic gas and steam emissions. The Alert Level remained at 3 (on a scale of 0-5). Areas deemed hazardous were within a 2-km radius from Benbow Crater and a 3-km radius from Marum Crater.

The governor of Bali extended the state of emergency to 26 October, noting that the Alert Level remained at 4 (the highest level on a scale of 1-4). The number of evacuees was 139,199 (spread out in 389 shelters).
