Turrialba volcano (Costa Rica): new ash eruptions

Eruption of Turrialba on 4 May with ejected bombs (arrows) (OVSICORI-UNA)
A new series of weak to moderately powerful eruptions have occurred at the volcano during the past days.
A small and short ash eruption occurred on 1 May, with a plume of a few hundred meters height. On 4 May, a more intense eruption occurred at 13:20 local time, ejecting an ash column that rose 2.5 km and caused ash fall in areas of the Central Valley to the west, before drifting over the Pacific 100 km distance.
During the eruption, several large bombs were ejected and fell several hundred meters from the crater.
According to OVSICORI, much of the eruptive process is dominated by the interaction of shallow ground water with a new, but probably relatively small body of magma that has risen in the conduit. Explosive activity of various strength is likely to continue for the near future.
