The lull in activity at Kīlauea Volcano continues ; in the East rift zone, the lava is encrusted in the cone on fissure 8 and has only a little incandescence. Some entrances scattered in the ocean persist, and drain a lava balance.

The black sand continues to accumulate in Pohoiki Bay, with a narrower area at the tip of the dike ... a weak point to watch for a possible reopening of access.

As part of the DECADE / Deep EarthCarbon Degassing project, the OVI / Ingemmet is installing a Multigas station at 5,900 meters altitude and 400 meters from the Sabancaya crater, which will measure and record in real time the levels of dioxide of carbon and sulfur dioxide emitted, transmitted by radio telemetry to the OVI in Arequipa.

This project is done in cooperation with various volcanological observatories in the world, and groups together the monitoring data of twenty active volcanoes.
