Eruption at Turrialba yesterday morning (OVSICORI-UNA webcam)
After several months of relative calm, the volcano began to erupt ash plumes again since 23 Oct. Some of the explosions have been relatively strong and caused very small pyroclastic flows limited to the crater area.

The origin of these emissions are likely phreatic explosions, i.e. caused by overheated ground water flashing to steam.
Whether this is the case or at least some fresh magma is involved is unclear. Seismic activity, which could suggest the rise of new magma, has been reported to have picked up recently.
