The explosive activity of the volcano continues.
A strong explosive eruption was recorded by the Instituto Geofísico (IGEPN) and VAAC Washington starting around 09:35 local time yesterday as huge spectacular ash plume rose up to upper tropospheric altitude of 41,000 ft (12,500 m). The clear sky darkened by dense dark ash content as some observers reported in social media. Moderate-to-strong ashfall was detected in Cantón Guamote including Chambo, Riobamba, Penipe, and Guano areas.
Satellite-based measurements of sulfur dioxide (SO2) concentrations in the atmosphere measured impressive approx. 25 kilotons (25,000,000 kg) in the plume.

Kilauea volcano (Hawai’i): new developed pond entered into main lava lake

According to Hawaiian Volcano Observatory (HVO) a small lava pond developed near the western fissure during 5-7 March.
On 7 March at about 13:00 local time a levee of the pond started to collapse allowing the pond lava to drain into the main lake. The lake has developed a subtle levee on its south margin (just below the center of the photo), with several lava streams cascading down onto the lower level on the eastern end of the levee.
A new lava flow was active north of the normal lava flow entering the lake. This new lava flow was perched above the lake surface, and fed a narrow channel entering the lake. The new stream was set within a collapse scar that resulted from the collapse of a small lava pond.
Minor changes in the geometry of the western fissure, like this, happen occasionally.
