Eruption anniversary of Mount St Helens (Janine)

UPDATE 09:00 UTC Piton de la Fornaise, La Réunion, Indian Ocean
The short lived eruption started at 20:10 local time and ended at 01:00, so a little less than 5 hours. Volcanic tremor is still high and the alert level is kept on Alert1 meaning that a second eruption may occur soon again. Lets hope that the webcams will be able to show it this time as nobody saw the first eruption due to bad weather.

Eruption report from the Alaska Volcano ObservatoryThe explosive eruption that started today, May 16, around 22:32 AKST (May 17 06:32 UTC) is continuing. A pilot reported that the eruption has produced an ash cloud as high as 34,000 ft asl, and the Worldwide Lightning Location Network has detected lightning associated with the cloud. Winds are currently to the south. Ash has not yet been detected in satellite.Schermafbeelding 2017-05-17 om 15.32.00

Sakurajima volcano, Kyushu, Japan, 29 April 2017, 15:10 UTC (Philippa)
The Japanese Meteorological Agency (JMA) report that ash-rich, explosive eruptions have resumed at the Showa crater of Sakurajima volcano in south-west Japan following a hiatus of activity from this crater since July 2016. Eruption plumes have been reaching altitudes of between around 1,000m and 2,800m above the Showa crater, with the latest eruption occurring at 09:37 UTC today.
The screen grab (below) of one of today's Sakurajima eruptions was captured via JMA's webcam by James Reynolds (@EarthUncutTV):


Shiveluch volcano, Kamchatka, 21 February 2017, 01:00 UTC (Philippa)
A Volcano Observatory Notification for Aviation (VONA) was issued yesterday by (monitoring agency) KVERT stating that an explosive eruption had begun at Shiveluch volcano at 05:09 UTC. The ash column was observed via a webcam to reach a maximum height of between 5.0-5.5 km above sea level (a.s.l.) driving in a NW direction.

Bogoslof volcano, Alaska, 21 February 2017, 00:30 UTC (Philippa)
USGS/Alaska Volcano Observatory (AVO) yesterday reported an explosive eruption at Bogoslof volcano at 02:08 UTC. The ash plume, which reached a height of around 25,000 ft. above sea level (a.s.l.) / ~7.5 km a.s.l., was detected from seismic, infrasound, lightning, and satellite monitoring. A rare ground-based photo was captured (see image below), and inhabitants of neighbouring island Unalaska have assisted AVO with collecting volcanic ash samples from the eruption plume fall-out for analysis.

Sinabung volcano, Indonesia, 18 February 2017, 15:50 UTC (Philippa)
An explosive eruption at Sinabung volcano was reported at 17:18 local time today by the Postal Sinabung (PGA) monitoring station. The plume reached an estimated height of 3 km above sea level (a.s.l.) and dispersed in a SEE direction. Accompanying seismic activity lasted for around 399 seconds.
The image (below) was taken by Endro Sewa at a distance of around 2.5 km from source.

Bogoslof volcano, Alaska, 18 February 2018, 15:25 UTC (Philippa)
(monitoring agency) USGS/Alaska Volcano Observatory (AVO) reported two short-lived explosive eruptions today at Bogoslof volcano: one at 00:46 UTC and one at 13:26 UTC. Both eruptions were detected from seismic and lightning data. Satellite imagery suggested that the plume height of the second eruption reached at least 25,000 ft. above sea level (a.s.l.) (~7.6 km), and a SIGMET (Significant Meterological Information bulletin) later issued via the Volcanic Ash Advisory Centre (VAAC) Anchorage estimated the top of the ash plume height to be around 35,000 ft. a.s.l. (~10.7 km).

The tweet below, issued by the National Weather Service, relates to previous explosive eruptions at Bogoslof volcano and their detection.

Sabancaya volcano, Peru, 18 February 2017, 13:45 UTC (Philippa)
