Volcano news: Poás volcano, Costa Rica
Poas volcano (Costa Rica) activity update
Friday May 03, 2013 10:05 AM | BY: T
A phreatic explosion occurred from the crater lake on 1 May.
Wednesday, May 01, 2013
A small earthquake swarm occurred yesterday, probably caused by fluid movements bringing heat into the crater lake. Seismicity has calmed down today again.
Saturday, Apr 20, 2013
Minor volcanic unrest that had affected the volcano in the past days seems to be over.
Wednesday, Apr 10, 2013
The seismic signal suggests increased tremor and signals of possible hydrothermal explosions. An elevated SO2 concentration above the area suggests a higher level of degassing activity.
Thursday, Mar 14, 2013
A small swarm of local earthquakes occurred at or near Poas yesterday, possibly related to or indicating small hydrovolcanic explosions.
Tuesday, Oct 30, 2012
Early Sunday morning, 29th October residents reported a rumbling sound from Poas. Then at around 13:00 (local time) the volcano ejected ash and mud 500 M above the crater. Two other eruptions took place at 16:34 and 16:44 (both local time). The eruptions were most probably phreatic. The Alert Level remains at GREEN.

Volcano Eruption Special
: 11-16 Feb 2019: short-notice special tour to see the ongoing eruption of Karangetang volcano in northern Indonesia. Starting and ending in Manado. Small group 2-6 people, experienced volcano expedition leader from our team (Andi).
Volcano Special Tours
: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
Top 20 quakes in 2016
: Several magnitude 7 quakes occurred in 2016 (but none above M8): Papua New Guinea, NZ, Ecuador, Solomon Islands, Sumatra, Chile, Alaska and others - nearly all major earthquakes were located near active subduction zones.
