In Guatemala, the Fuego is the seat of 4-6 explosions per hour, accompanied by expulsion of gray ash to a height of 4200-4500 meters asl.

Some explosions have incandescent emissions to 100-200 m above the crater rim, with avalanches in benefits to the edge of vegetated areas.

Santiaguito seems to have calmed down and is only degassing amount to 300 meters above the crater before spreading north.

In Hawaii, the lava flow 61 G remains active on the coastal plain and the lava front is still 820 meters of the ocean, according to satellite measurements, different from field measurements.

The tilt meters at the summit of Kilauea recorded a slight inflation ; small earthquakes marked the southern part of the caldera Monday. The level of the lava lake in Halema'uma'u has edged up to 26 meters under the floor; it is agitated by intermittent spaterring and emits a vigorous plume of volcanic gases.

Small seismic swarms located between 5 and 11 km below the upper flanks west and north of Mauna Loa, in response to the stress of a slow accumulation of magma to the summit and in the SW rift area. Inflation, measured by GPS and InSAR satellite measurements confirms this magmatic contribution.

In Indonesia the Sinabung presented this July 19th at 6:40 an eruption, accompanied by an ash plume rising to 2,000 meters, vertically above the crater, in lack of wind.

Bromo continues to present a beautiful plume, less loaded with ashes this morning.
