Kilauea / Pu'u O'o - The 61 g lava flow remains active: on a satellite image we can see several breakouts on the lava field, the largest located about 2 km south-east of the vent. Others are visible above the pali, and on the costal plain. The thermal anomaly is still present at the sea entrance to Kamokuna.

A short-lived eruption began this March 13 at 11:31 UTC / 3:31 AKDT on the Bogoslof. She ended 12 minutes later, characterized by an ash cloud detected by satellite and the infrasonic system.
The aviation code remains at orange and the level of volcanic alert at Watch.

Copahue, on the border of Chile and Argentina, has been presenting for some days a steam and gas emission, which remains low.
Its volcanic alert level remains to yellow, due to its seismicity above the base level and the instability of the hydrothermal system.

Once again, it is in volcanic landscapes that future astronauts train ... after Crater of the Moon, Hawaii, here are the teams of ESA / Project Pangea on the island of Lanzarote, where they become familiar with the way to collect rock samples.
Lanzarote was chosen for its geological similarity with Mars planet: its of volcanic origin, its mild sedimentary processes due to the dry climate, little vegetation and a well preserved landscape.
