Michael volcano eruptions
Stratovolcano 990 m / 3,248 ft
United Kingdom, South Sandwich Is, -57.78°S / -26.45°W
Eruption list: 2016 (?), 2015, 2008 (?), 2006, 2001-03, 1995-98, 1823 (?), 1819
2008 activity
A thermal anomaly was detected on MODIS satellite imagery on 25 Oct 2008, suggesting a possible eruption.
2006 eruption - probable lava lake
ASTER satellite images from 28 October showed a strong hotspot at the summit crater, where a new lava lake had possibly formed.

The intensity of the measured radiation was compared to Villarrica volcano in Chile, which is similar in size and probably similar in activity, and often has a small lava lake in its summit crater.
An ASTER image of Mt. Michael obtained on28 October 2006 created using energy in the visible near-infrared wavelength, with the inset showing a closer view of the summit crater. There are two small near-IR anomalies (band 3, 0.807 microns wavelength) in the otherwise dark center of the crater, shown as red spots in the colored image. The two anomalies suggest very high temperatures and support the idea that fresh lava may reside at the surface or a shallow level in the crater. Courtesy of Matt Patrick.

1997 eruptions
14 volcanic plumes were detected at Mt Michael volcano by satellite in 1997.
1996 activity
39 volcanic plumes were detected on satellite images during 1996.
1995 eruption - lava lake
A lava lake was detected with satellite images between April-July 1995. This was the first time, a lava lake was found in the South Sandwich Islands. 20 volcanic plumes were detected on satellite imagery during 1995.
ASTER satellite images from 28 October showed a strong hotspot at the summit crater, where a new lava lake had possibly formed.
