Sakurajima (Kyushu, Japan) [4]: (11 Feb) The volcano has been in a phase of elevated activity during the past days.
Several moderate to large explosions occurred with ash plumes rising up to 12,000 ft (3.7 km) altitude. At least 6 explosions were counted yesterday alone and VAAC Tokyo reports phases of continuous ash emission.

Popocatépetl (Central Mexico) [5]: A phase of near continuous steam / gas emissions took place yesterday, with some explosions ejecting ballistics onto the crater's outer flanks and producing plumes with some ash rising up to 1 km. Activity declined again in the evening.

Santa María / Santiaguito (Guatemala) [6]: No significant changes have occurred over the past days. Explosions from the lava dome occur at rates of about 1-2 per hour and produce ash plumes rising a few 100 m. The lava flows descending the dome, in particular on the SE side, are weakly active and produce small avalanches.

Fuego (Guatemala) [7]: After a short period with little effusive activity, a new lava flow has started to descend towards the Ceniza drainage. Strombolian activity at the summit remains weak.
