Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): While weak lava effusion and sporadic strombolian explosions from the New SE crater continue with little changes, the Bocca Nuova crater has started to produce occasional small ash emissions of sometimes elevated temperature (suggesting presence of magma near the surface).

Popocatépetl (Central Mexico): Activity has been low with less than 1 emission per day and no recent explosions.

Today's seismogram shows the magnitude 6.3 earthquake in southern Mexico early this morning.

Pacaya (Guatemala): According to INSIVUMEH, lava continues to flow from the vent (on the western base of the cone?), but is mostly inside small lava tubes. Strombolian activity at the summit vent seems to have decreased or ceased.

Fuego (Guatemala): A small lava flow continues to be active on the upper SE slope of the volcano. Explosions have been a bit weaker on average, with incandescent lava ejected to 150 m and ash plumes reaching 500-800 m above the summit.

San Miguel (El Salvador): NO significant changes in activity have been noted. Seismic activity remains elevated, but at stable levels lower than during the second half of February.
