Volcanic activity world-wide 1 October 2012: Heard Island, Krakatau, Kilauea, Popocatépetl, Fuego, Santiaguito, Tungurahua, Sakurajima

lundi oct. 01, 2012 14:09 | AUTEUR : T

MODIS satellite data showed hotspots at Heard Island volcano on 21 and 24 September 2012. This suggests that there was or perhaps still is some new activity at the volcano, although no further hotspots appeared on satellite data since 24 Sep.

Krakatau volcano is still calm, but a visitor to the volcano yesterday told us that the crater is strongly degassing.

Sakurajima volcano has picked up again the frequency of erupting with 3 explosions during the past 24 hours. Ash reached altitudes of 7-9,000 ft (2.1-2.7 km).

Popocatépetl produced 10 weak mostly steam explosions during 29-30 Sep. Crater glow is visible at night. The steam plume was less pronounced and only about 700 m high yesterday morning.

Fuego volcano continues its strombolian activity at unchanged levels, about 1 explosion every 2 hours, with ash plumes of up to 1 km height and incandescent material reaching 200 m above the crater. Shock waves are felt in up to 15 km distance during the strongest bursts. Fine ash fall occurs in nearby areas.

Santiaguito had 2 weak explosions this morning at 06:08 and 6:24 hours and a moderate one with incandescent material at 04:06 hours local time, generating ash plumes rising 600-800 m. Some lava flows are reported still active and produce small block avalanches from their fronts.

Seismicity at Tungurahua volcano remains moderate to low. Direct observations of summit activity are hindered by near constant cloud cover, but there are no indications of recent explosions or ash emissions.


At Kilauea volcano on Hawai'i, the lava flows increased their advance down the pali. One front entered the remaining kipuka within the Royal Gardens subdivision.
The flows are easily visible from the County Viewing Area located to the east in Kalapana and are becoming more into view from the west side of the flow field at the end of Chain of Craters Road.
