Volcanic activity worldwide 28 May 2013: Popocatépetl, Nevado del Ruiz, Copahue

Explosion from Popocatépetl this morning
Popocatépetl (Central Mexico): An explosion early today at 05:03 h (local time) ejected incandescent fragments to 1.5 km distance from the crater on the northeastern slope and generated a column of ash that reached more than 2 km height above the crater and was dispersed to the SW.
Ash emission yesterday at 18:03 and 18:04 (local time) seen through the web cam in Piraña. (INGEOMINAS)
In addition, 28 smaller steam-gas-ash explosions occurred during the past 24 hours and a constant steam and gas plume is rising from the volcano.
Nevado del Ruiz (Colombia): Yesterday evening, a seismic swarm and a tremor episode occurred, followed by small ash emissions from the Arenas crater observed on the webcams of INGEOMINAS.
At the moment, seismic activity has calmed down again, but small volcanic quakes are still elevated in numbers. It has to be seen if more magma is going to intrude and possibly lead to an eruption in the near future. The alert status remains at orange.
Copahue (Chile/Argentina): (27 May) An eruption of the volcano could be imminent. SERNAGEOMIN and Civil Protection have raised the alert level to "red", based on the increasing earthquake activity under the volcano. Although so far no volcanic tremor (often a sign of eruptive activity) nor ash plumes have been detected via satellite, citizens of Caviahue in Argentina across the border from Copahue have reported explosions and incandescence from the volcano.
The most likely scenario for the near future is probably a small explosive eruption such as in December 2012. Schools in towns surrounding the volcano have closed due to the threat of an eruption, the Eruptions Blog reports.

Gamkonora (Halmahera): Increased earthquake activity has triggered an eruption alert by VSI, who raised the volcano's status to 3 ("Siaga", "warning") out of 4 this morning. Indonesian volcanologists reported that the degassing plume from the summit crater of the volcano has turned dark, which suggests the presence of ash (probably phreatic in origin) since 25 May. ...

Etna (Sicily, Italy): Etna today is free of clouds, but strong winds with gusts up to 70 km/h speed prevail. No further significant earthquakes occurred. The only activity remains degassing, and occasional small explosions, not visible, deep inside Bocca Nuova, based on seismic observations (OPEC). ... [more]

Chirinkotan (Northern Kuriles): The remote volcano in the northern Kuriles is probably in eruption, the latest SVERT report and satellite images suggest. A plume of gas and steam, and possibly some minor amounts ash was seen with the MODIS sensor onboard the NASA Terra satellite this morning. ... [more]
