During the last 24 hours at Popocatépetl, Cenapred recorded 57 exhalations of gas, water vapor and a little ash,
and two explosions, respectively at 5:10, accompanied by a plume of 1,500 meters and incandescent fragments , and at 7:30, which generated an ash plume of 3,500 meters; the ashes dispersed to the northeast with possible falls on Huejotzingo, San Nicolás de los Ranchos, San Buenaventura, Santiago Xalitzintla and San Andrés Calpan.
A short Strombolian episode was observed from 5:00 am to 5:15 am, with emission of incandescent fragments on the east-southeast flank of the volcano.
It is also an opportunity to greet our friend Robin Campion, who explains his work as a volcanologist at UNAM.

Volcanologist Robin Campion has been studying the activity of Popocatépetl for more than six years in the context of risk prevention.
Among the active Indonesian volcanoes, I remember today
Bromo and its gray ash emissions to the northeast.
The alert level is 2 / waspada and the Vona is orange.

In Karangetang / Sulawesi north, which has been in continuous operation since 25 November 2018, it has only been observed in recent days at the two summit craters.
On March 10, a Sentinel 2 image shows hot spots at both craters and degassing, more important at the south crater.
The PVMBG reports a white plume of 100-150 meters high on March 12 and 13, weak to moderate intensity at the main crater, drifting east and southeast.
The seismicity is marked these two days by avalanche earthquakes, blast earthquakes, multi-phase hybrid earthquakes and some superficial volcanic earthquakes. Continuous tremor is perceived, with a dominant 0.25 mm.

In Peteroa / Chile, eruptive activity continues on March 13, 2019, with significant brown ash emissions.
