In Guatemala, in the line of increase of its activity since a few months, the Pacaya presents now an increase of its explosive activity, with 3 to 5 episodes per hour, generating minor spillovers up to 10 km in direction north and north-east .

The cone in the Mackenney crater continues to experiment  successive phases of construction and destruction.

The lava flows, fed by this activity, move towards Cerro Chino and reach about 600 meters long.

Since August 26th, seismicity has been rising at Shinmoedake, accompanied on August 27, by a plume of white vapor rising to a hundred meters above the crater.

The inclinometers located to the south of the volcano do not show any inflation ... consequently, the JMA did not raise the alert level, in force since June 28, 2018, which remains to 2 accompanied by a prohibited zone of 2 km.

At Etna, the activity stopped at the "vent of the saddle" of the southeast crater, replaced since the 27 August in the morning by strombolian activity at "puttusiddu", which feeds a new lava flow. The latter follows the brief casting of August 23 in the evening.

The activity remains modest, with a tremor of smaller magnitude than during the activity of the saddle.
