Map of today’s active volcanoes

Stromboli (Eolian Islands, Italy): The National Institute of Geophysics and Volcanology (INGV) in Catania reported an intense spattering activity in the North crater area.
At about 12:30 UTC, a new lava overflow followed the increased activity. Scientists concluded that part of the rim of the crater collapsed as accumulated lava material was loose to destabilize, resulting in the small lava overflow.

Seismic recordings detected no significant values of tremor, it had remained at low-to-medium levels.

Eldey (Reykjanes Ridge, Iceland): The latest Icelandic Institute of Earth Sciences statistics revealed on 31 July indicate a notable reduction of the effusive eruption.
The estimated lava flow discharge rate during 23-31 July was measured to be about 5,0 m3/s. The previous values, detected between 18 and 23 July, signalized the discharge rate of the lava at about 9,0 m3/s, which is nearly double the drop in the rate.

As of 31 July, the outpouring lava has covered an area of 1,5 km2 with a volume of approx. 15,9 million m3.
Since 26 July, the seismic station has recorded about 150 earthquakes in the area of Mt. Keilir, precisely located beneath the northernmost part of the intrusion dyke. The largest quake with a magnitude of M 2.1 has been registered during the investigation period so far.
