Due to the instability of the cliffs, volcanic projections and gases and possible collapse of the delta, the Coast Guard established a security zone on 28 March, extending 300 meters in all directions from the point of entry of the lava into the ocean; It must remain in effect until September.
In the Pu'u O'o, the flows on the upper part of the lava field continue their progression above the pali. Short breakouts of short duration are reported on the costal plain.

In Kamchatka, the explosive eruption continues at Klyuchevskoy. A plume of ash was noted at 5,500-6,000 meters asl, drifting 85 km to the ESE of the volcano.


In Kambalny, ash explosions produce a plume rising 30 amrs to 4,000 meters asl, then drifting 78 km to the south of the volcano.


The two volcanoes remain in orange aviation alert.

At Pacaya, atmospheric conditions do not allow a direct observation of the volcano, but the PCG seismic station shows an internal tremor associated with the degassing and constant ascension of magma in the main duct.
