An explosive eruptive episode occurred on March 27 at 1:23 UTC / March 26 at 19:23 local at Popocatépetl. He produced an ash plume 3,000 meters high, drifting to the northeast, according to Cenapred.

Incandescent materials were projected more than 2km from the crater, causing fires on the slopes of the volcano.

The VAAC Washington reports volcanic ash at an altitude of 8,500 meters asl, to dissipate within 12 hours.

The activity remains in the standard of Amarillo alert fase 2.

At Kilauea, the USGS reports a great calm, and has brought the volcanic alert level back to "normal"; the aviation code is in turn "green".

Air quality has been described as better for years ... Kilauea's total sulfur dioxide emission ratio was less than 100 tonnes per day, a level lower than before the 2018 eruption.

During the past week, seismicity has remained low; the deformation measurements always show a recharge of the magma reservoir of the East rift zone.

Small collapses highlight the instability of the Pu'u O'o cone.
