Epicenters of recent earthquakes south of Hekla
Hekla (Iceland): Small earthquake swarms occurred at shallow depths during the past days near the volcano. The quakes were located approx. 6-10 km south of Hekla volcano and at shallow depths around 5 km.
Weak steam / ash plume from Klyuchevskoy volcano today
The largest quakes were two magnitude 2.6 events at 4 km depth on Thursday (9 April). It is impossible to say whether the earthquakes are linked to volcanic activity and thus might be precursors of a new eruption, but Hekla is probably the most likely candidate volcano for the next eruption to occur on Iceland.
One of the country's most active, and the most frequently erupting volcano, Hekla has been believed to be "due" and have its magma chamber filled for several years now. Known for not giving much precursory signals (and only few earthquakes), an eruption would not be a surprise at all.
Kliuchevskoi (Kamchatka): After less than two weeks pause, the volcano started to erupt again - mild strombolian explosions at the summit crater and small ash emissions.
KVERT raised the alert level again to yellow and noted that seismic activity has also shown an increase recently.

Ubinas (Peru): After several months of calm, the volcano started to erupt yesterday morning again. An initial moderately strong explosion produced an ash plume that rose 2.5 km above the volcano and drifted SE to the Ubinas valley, where approx. 1.5 mm of ash fall occurred in 6 km distance. ...

Tungurahua (Ecuador): The volcano entered a phase of increasing activity again. New ash emissions, tremor episodes and increased SO2 output occurred during the past days and suggest that a new pulse of magma is on its way. This could lead to a new, possibly intense eruptive phase in the near future. ... [more]
