Turrialba volcano (Costa Rica): new series of phreatic explosions

A series of eruptions has been occurring from the volcano's active western crater during the night and this morning and is likely still going on.
Costa Rican volcanologist describe the explosions which each lasted a few minutes as phreatic, i.e. driven by overheated water from the hydrothermal system suddenly flashing into steam. The first explosions occurred at 21:22 and 22:16 local time last night and were followed by similar ones at 07:22 and 08:25 this morning.
The eruptions were similar to many others in the ongoing phase of intermittent explosions at the volcano during the past months; they ejected ballistic blocks of high temperature to the crater rim and generated ash plumes that rose several hundreds of meters before drifting SW where ash fall occurred in nearby areas.
