The Observatory Simológico Volcano of Costa Rica (OVSICORI-UNA) confirmed that a new ash eruption occurred at Turrialba volcano in the afternoon around 15h20 on 12 Jan.
The eruption was first noticed by park rangers and local residents.
During the previous day, numerous rumblings could be heard from the mountain. According to OVSICORI-UNA, the eruption started between 3:10 and 3:20 pm and produced an ash plume from a vent on the southeast flank of the main crater in an area known as "La Quemada".
The ash reached a height of approx. 500 m above the crater rim, and was transported to the N-NW Direction by prevailing winds at an altitude at around 4 km.
Der Ausschlag ist bis 18:14 am selben Tag mit einer starken Emission von Asche und Gase bestehen.
Aus dem Central Valley, Beobachter 2 Federn sehen könnte: eine Weile, reich an Dampf aus dem Krater, die während der phreatische Eruption am 5. Januar 2010 gebildet hatte und eine dunkle reiche Aschenwolke aus der aktuellen Ausbruch-Website unter La Quemada.

Fieldwork confirmed an unusual output of gas from several fumaroles along the S outer wall. Areas burned by acute acidification have extended in the last month.

Within the W crater, temperatures of fumaroles reached 280 degrees Celsius and native sulfur was present. ... [mehr]
