Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Shishaldin report has been published on 08 Jan 2020 09:18.
AVO reported that the eruption at Shishaldin continued during 1-7 January. Seismicity was low during 1-2 January and elevated surface temperatures identified in several satellite images indicated continuing lava effusion. Seismicity began increasing at 0930 on 3 January and within several hours a brief period of sustained ash emissions produced plumes that rose as high as 8.2 km (27,000 ft) a.s.l. and drifted about 120 km SE. The ash plume produced minor amounts of volcanic lightning. Seismicity declined abruptly after the event. Satellite images acquired the next day showed no noteworthy activity; ash deposits from the day before mantled the upper flanks, lahars on the upper parts of the edifice and on the SW flank were visible, and lava flows on the upper NW and NE flanks were 1-2 km long. During 5-6 January seismicity was low but above background levels and elevated surface temperatures were visible in satellite images. A photo taken from Cold Bay (93 km NE) on 6 January showed glowing lava flows on the flank. Seismicity increased at around 0500 on 7 January and was followed by observations of an ash plume drifting NE at an altitude of about 5.8 km (19,000 ft) a.s.l. Seismicity then decreased for a few hours. Another episode of elevated seismicity was accompanied by an increase in the altitude of the ash plume; it rose to 7.6 km (25,000 ft) a.s.l. and seemed to have a denser ash content. The Aviation Color Code was raised to Red and the Volcano Alert Level was raised to Warning. Volcanic lighting was detected in the cloud and volcanic infrasound signals were detected at regional stations. Seismcity significantly decreased around 1200 and remained low. Later that day the Aviation Color Code was lowered to Orange and the Volcano Alert Level was lowered to Watch. Source: US Geological Survey Alaska Volcano Observatory (AVO)
