Volcanic activity world-wide 29 October 2012: Kilauea, Popocatépetl, Fuego, Santiaguito, Galeras, Michael, Sakurajima

lundi oct. 29, 2012 17:13 | AUTEUR : T

The week starts with little significant volcano activity to report. Some updates include:

Earthquake activity in or near the upper eastern rift zone of Kilauea volcano on Hawai'i has been increasing. A magnitude 3 quake occurred in the northern part of the caldera today.
Lava flows southeast of Pu`u `O`o continued to be weakly active on the coastal plain.

Popocatépetl has been decreasing again after rising over the past week. During 27-28 Oct, there was only about 1 emission per hour. Few of them produced small ash plumes.

Fuego volcano has a few weak explosions and continues to alimentate the lava flow towards the Ash Canyon which is now about 400 m long.

Few weak ash explosions occur from the Santiaguito lava dome and the block lava flows from its summit vent remain weakly active.

Occasional small ash eruptions continue to occur at Galeras volcano in Colombia, such as today.

A thermal hotspot can still be seen at Michael volcano in the South Sandwich Islands.

In the past days Sakurajima volcano returned to average levels of activity and produced 1-2 mild explosions per day.
