Poás volcano (Costa Rica): new phreatic eruption
jeudi mars 20, 2014 17:52 | AUTEUR : T
Phreatic explosion at Poàs volcano yesterday morning (Ovsicori webcam)
Another moderately sized phreatic eruption from the crater lake of the volcano took place yesterday morning at 07:08 local time.
The explosion ejected steam, water, mud and rocks to about 100 m height.
According to Ovsicori, this type of intermittent, sporadic explosive activity has been characterizing the volcano's typical behavior since 2006. Similar eruptions can be expected in the coming days or even months.
The so-called phreatic explosions themselves are caused by overheated fluids in the hydrothermal system beneath the lake, not directly by fresh magma, but can be very dangerous for anyone near when they occur.

An impressive phreatic eruption took place at the volcano yesterday shortly after noon (local time). So-called cypressoide-type jets of water, mud, and solid blocks were ejected in circular directions from the crater lake to heights of approx. 400 m. The webcam that captured the event was covered with mud. ... [details]
