Activity of Popocatépetl, Sabancaya, La Fournaise and seismic swarms in Reykjanes.

The last 24 hours were calm at Popocatépetl, with 53 low-intensity exhalations accompanied by water vapor, gas and small amounts of ash, an explosion at 9:32 local with emission of a plume of ashes 1 km above the Crater, then dispersing on the State of Mexico. Nocturnal incandescence is observed at the crater.

Seismicity is marked by two volcano-tectonic earthquakes with magnitudes 1.6 and 1.4.

The Sabancaya has been experiencing more frequent explosions since early July, accompanied by plumes of ash rising to more than 5,500 meters above the crater. The seismicity is characterized by hybrid earthquakes, and shows the fracturing of rocks and magmatic movements. The degassing of SO₂ is also more consistent. The assembly illustrates the arrival of a quantity of new magma richer in gas.

At La Fournaise, the eruption continues according to a classic model, with a relatively constant intensity of the trémor and a tendency towards a rebound in inflation.

The eruptive cone reaches 20 meters and contains two active mouths, one of which is projected incandescent material 20-30 meters high, the other on the north wall of the cone which has built a small rampart on the west side .

The bad weather conditions do not allow a good observation by the webcams.

The seismic swarm that marks the Reykjanes peninsula on 26 July continues; 9 earthquakes between M 3 and 4 were recorded yesterday and this morning, felt in the Reykjanes peninsula and in the Reykjavik area.

Two earthquakes of M 3,2 and 4,5 were recorded on 26 July at Myrdalsjökull.
