The volcano has once again entered a (brief?) phase of stronger effusive and explosive activity. The Activity has increased since yesterday 14h20 local time, INSIVUMEH reports. A new lava flow has started to descend from the summit crater towards the Ceniza drainage and has reached a length of 1300 m.
Current seismic signal from Fuego (FG3 station, INSIVUMEH)
Weather conditions did not allow direct observations, but it seems that associated explosions and/or possibly pyroclastic flows (which often are triggered by collapses of Fuego's steep lava flows) have created an ash plume rising to 5 km altitude. So far, however, no evidence of actual pyroclastic flows have been found, although they could (and likely will) happen any time.
On the other hand, the current seismic signal suggests that activity has already decreased significantly.

The volcano has been calmer today, with only 10 mostly weak strombolian explosions registered, and maximum ash plume heights of 600 m. Incandescent tephra was seen ejected to 100 m above the crater and rolling down towards the Ceniza canyon. Strong degassing with turbine-like noises lasting up to 3 minutes were heard. [more]

Compared to the previous days, activity has a bit decreased. INSIVUMEH reports few weak to moderate explosions, and small glowing avalanches from the crater towards the Ceniza drainage visible at night. A new lava flow is predicted to re-appear in the coming days. ... [more]

The rhythm of explosions remains similar. A total of 15 weak to moderate events with ash plumes rising 400-900 m were mentioned in INSIVUMEH's latest report for the period 14-15 March. [more]

An increase in explosions has been observed recently. INSIVUMEH reported 16 events, out of which 9 were characterized as "moderate" with shock waves that rattled windows and roofs, and incandescent tephra reaching 100-150 m height. ... [more]
