Volcanic Activity Worldwide: Monday May 23, 2016

Source: Volcano Discovery Stromboli (Eolian Islands, Italy): The activity at the volcano has picked up recently and is now again at (fluctuating) moderate levels similar to what it has been during much of the past 10-15 years – extremely rewarding for those who climb it in the evening. Apparently, the magma column inside the conduits…

Volcanic Activity Worldwide: Tuesday May 17, 2016

Sinabung (Sumatra, Indonesia): Two small to moderately sized pyroclastic flows occurred this morning at the volcano. The larger one at 06:16 local time (image) produced a pyroclastic flow that traveled 2700 m on the SE side and a co-ignimbrite ash plume that rose 2500 m into the sky. Santiaguito (Guatemala): The activity at the Caliente…

Volcanic Activity Worldwide: May 14, 2016

Source: Volcano Discovery Stromboli (Eolian Islands, Italy): Following a phase of very low activity during most of March-April (often with several hours between small explosions only), activity has picked up again and strombolian-type explosions, mainly from the western and eastern vents in the crater terrace, have been more regular. According to INGV’s monitoring data, activity…

Volcanic Activity Worldwide: May11, 2016

Source: Volcano Discovery Shiveluch (Kamchatka): (9 May) KVERT reported that during 21-29 April lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions, and hot avalanches. Satellite images showed an intense daily thermal anomaly over the dome. The Aviation Color Code remained at Orange. Mount St. Helens (Washington): Since…

Volcanic Activity Worldwide: May 7, 2016

Source: Volcano Discovery Niigata-Yake-yama (Honshu): An increase in small earthquakes has been detected under the volcano located on the border between Niigata and Nagano Prefecture recently. In addition, a slight increase in fumarolic activity on the eastern side of the summit crater was noted and some inflation of the volcanic edifice recorded.  According to the…

Volcanic Activity Worldwide: April 25, 2016

Kliuchevskoi (Kamchatka): The activity of the volcano has intensified, in particular during the past 24-36 hours. KVERT reported that strong strombolian explosions produced an ash plume that rose to 8-9 km altitude that drifted more than 400 km to the SW. Webcam images have been mostly unclear, but view from this evening (dawn in Kamchatka)…

Volcanic Activity Worldwide: April 19, 2016

Source: Volcano Discovery Nyamuragira (DRCongo): The lava lake at the bottom of the inner pit in the volcano’s summit caldera has recently disappeared, a recent survey by scientist from the Goma volcano observatory (OVG) and UN. It is not known when exactly this happened and how, but the thermal signal stops abruptly around 1 April,…

Eruption of Santiaguito on 11 April 2016 Source: Volcano Discovery Santiaguito (Guatemala): A violent explosion associated with a partial dome collapse occurred Monday morning at the Caliente dome. The eruption generated an ash column that rose several kilometers and a pyroclastic flow that traveled through the canyon draining from the dome complex to the SE.…

Volcanoes Today, 13 Apr 2016: Suwanose-jima Volcano

Source: Volcano Discovery Suwanose-jima (Ryukyu Islands): The strombolian activity at the volcano’s O-take crater continues to be relatively intense. VAAC Tokyo reports low-level ash plumes at approx. 6,000 ft and incandescence from the activity can be seen from neighboring islands. Currently erupting: Alaid (Northern Kuriles): intense thermal signal from summit crater, strong degassing (updated 31…
