Svartsengi (Reykjanes peninsula, SW Iceland): The number of daily earthquakes in the area of the Sundhnúka crater row continues to increase. According to geophysical model calculations, there is by now enough magma volume and pressure built up in the shallow underground reservoir that a new eruption is likely in the coming days.
About sixty earthquakes were recorded in the area over the last 24 hours, compared to an average of 30 quakes per day just over a week ago. At the same time, the speed of ground uplift has slowed, a phenomenon that had also been observed before previous eruptions.

Erta Ale (Danakil depression, Ethiopia): Our local geologist and guide for VolcanoDiscovery Ethiopia, Enku Mulugeta, carried out a field observation of the volcano in late July to provide information about the ongoing elevated effusive activity.
In the southern pit crater area, pulsating lava fountains continue from a chain of at least five dome-shaped hornitos, generating fresh fluidal bombs and lava flows. Hornitos (also called spatter cones currently) are arranged in a north-northeast oriented linear area distant about 200 meters from each other.
The southern lava lake layering continues as multiple lava flows spill out from hornitos in the south-southeastern direction.
