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.

This activity follows passive and continuous ash emissions since the end of last week, following a slight magmatic intrusion.

Ash falls and a smell of sulfur are reported on San Ramon de la Unión, Zapote, the neighborhoods of Goicoechea, Curridabat, Guadalupe, Coronado, Concepción de Tres Ríos, Lourdes de Montes de Oca.

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

- 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.
