Activity of Turrialba, Ebeko, Agung, Sinabung and Dukono.

This 6 February at 7:30 local time, the Turrialba was marked by a strong eruption, accompanied by a plume of 1,000 meters above the crater.

Another explosion occurred at 8:12, with a 500-meter plume above the crater.

In Indonesia, activity continues on several volcanoes according to a usual pattern in recent days

- The Agung, often covered with fog, presented a small white plume at 100-200 m. above the summit.

Seismicity is characterized by a deep volcanic earthquake, 7 superficial volcanic earthquakes and 5 emission earthquakes.

- The Sinabung did not have eruptions yesterday, and the summit was overcome by a low emission of steam rising between 100 and 600 meters above the main crater

These two volcanoes remain on alert level IV

- The Dukono, in alert level II, is not observable for two days because of the fog, but the eruptive activity continues there.
