Volcanic activity worldwide 20 Jun 2013: Pacaya, Fuego, Popocatépetl, Galeras, Paluweh, Nevado del ...

Thursday Jun 20, 2013 16:21 PM |

SO2 plume from Nevado del Ruiz 18 June (NOAA)
SO2 plume from Nevado del Ruiz 18 June (NOAA)
Paluweh (off Flores Island, Indonesia): Activity from the lava dome continues with occasional explosions and / or collapse events, but has been decreasing over the past weeks.
An ash plume at about 8,000 ft (2.4 km) altitude was observed on satellite data yesterday (VAAC Darwin).

Popocatépetl (Central Mexico): Activity has decreased to about 2 weak emissions of steam and gas, sometimes some ash per hour.

Pacaya (Guatemala): Weak strombolian activity has resumed, with small explosions about every 10 minutes that produce small ash puffs. Some of the explosions are audible, but most are only inferred from the seismic signal. Volcanic tremor accompanies this process.

Fuego (Guatemala): Activity both effusive and explosive has remained relatively unchanged and weak. Ash plumes rose 200-500 m above the crater and eject incandescent material to up to 100 m. The lava flow towards the Ceniza drainage was 250 m long this morning and produced occasional small avalanches.

Machin (Colombia): INGEOMINAS reports no significant changes - weak seismic activity continues SE of the principal dome at depths between 6-7.5 km and maintains alert level yellow.

Galeras (Colombia): Seismic activity has been lower during the past week. No recent ash explosions have occurred.
The other volcano at yellow alert monitored by Pasto Observatory, Cumbal, continued to show fluctuating, weakly elevated seismic activity.

Nevado del Ruiz (Colombia): Activity over the past days has been characterized by continuing strong degassing (elevated SO2 emissions), at times creating a steam and gas plume rising up to 1600 m.
Seismic activity has remained elevated and dominated by shallow volcano-tectonic quakes in areas SW, NW and N of the Arenas crater.

Sotará (Colombia): INGEOMINAS - Popayan volcano observatory reports no significant changes. Occasional small earthquakes continue to show the volcano is at unrest.
Nevado del Huila's degassing and seismic activity have remained stable at low levels.

Eruption from Popocatepétl yesterday morning
Monday, Jun 17, 2013
Veniaminof (Alaska Peninsula, USA): The eruption continues at low levels. Recent satellite images show very high elevated surface temperatures at the intracaldera cinder cone consistent with continued effusion of lava. No plumes have been observed in satellite images nor reported by pilots or local observers. (AVO) ... [meer...]
