Tungurahua volcano (Ecuador): increase in activity

Mild to moderate ash emissions, with ash plumes rising 1-2 km above the crater, have become more frequent over the past days, suggesting the volcano's activity has started to picking up. An explosion at 04:33 yesterday morning was seen ejecting incandescent material that rolled down the western flank to up to 1 km distance.

Light ash fall occurred later in Chacauco, Cotaló and Manzano. The ash was reported to be black and red in color and sugary in grain size. The first (color) suggest that it is from new magma (as opposed to typically gray-brown colored ash from pulverized older rock). The volcano observatory also reported an increase in seismic activity associated with fluid movements.
One possibility is that the volcano (after all, one of the world's most active ones) enters a more vigorous phase of activity in the near future, as often occurred in the past.
