Volcanos

 

Tolbachik (Kamchatka): KVERT reports no changes in the activity of any of the currently active volcanoes in Kamchatka.

Chirinkotan (Northern Kuriles): Some activity is occurring at the volcano. On MODIS Terra satellite images from 5 June, a moderately large steam plume can be seen drifting from the volcano. SVERT has raised the alert level to yellow on 8 June.

Sakurajima (Kyushu, Japan): After 10 days of almost no activity, the volcano has woken up violently with 3 powerful explosions last night (at 22:05 and 23:58 UTC, ash plumes to 10-13,000 ft) and this morning at 04:26. The eruption this morning appears to be one of the largest explosions for a long time, producing an ash plume rising to 16-20,000 ft (5-6 km) altitude. An SO2 plume is also visible on satellite data.

Taal (Luzon, Philippines): A pulse of more frequent earthquakes (7-9 per day) has been detected under the volcano in recent days. Other parameters show at present no significant changes. A slight increase in water temperature (from 33.0 to 33.9 deg C) and the level of the crater lake were measured on 6 June.

Manam (Papua New Guinea): A SO2-enriched plume is visible at Manam today.

Pavlov (Alaska Peninsula, USA): Activity (external and internal) has been decreasing, although now intermittent ash emissions and possibly effusion of lava continue, AVO reports.

Popocatépetl (Central Mexico): The rate of emissions has dropped to less than 1 per hour, but more (small) earthquakes have occurred and a large SO2 plume is visible yesterday on satellite images, suggesting that new magma could be currently intruding at depth. Weak glow is visible from the crater at night.

Pacaya (Guatemala): The volcano has been quiet yesterday. No explosions occurred. INSIVUMEH reports moderate steaming only.

Nevado del Ruiz (Colombia): Two shallow volcanic-tectonic earthquakes of magnitudes 2.8 and 2.9 occurred this morning at 05:39 local time. Quake hypocentres were at 5 km SW beneath the Arenas crater.
