Etna (Sicily, Italy): 7 days since the last paroxysm, Voragine has returned again to produce mild strombolian activity, emitting small ash plumes, and, occasionally, beautiful steam rings:

Katla (Southern Iceland): (29 Jul) Another small swarm of earthquakes has been occurring under the ice cap of the volcano since yesterday.
…29 Jul:
There are no indications from the Norwegian Meteorological Agency’s data that subglacial eruption caused the glacier flood. Although this runoff was unusually large, it was due to geothermal heat in the glacier’s cauldrons, causing meltwater to accumulate and then surge ahead of the glacier. A GPS meter on Austmannsbunga shows clear signs that the changes measured in the caldera are from a regular glacier run. However, the reason for the release of more water than usual from such runs remains unclear.
This afternoon, the Coast Guard conducted a flight with scientists from the Icelandic Meteorological Office and the University of Iceland to investigate the situation. During the flight, it was confirmed that the runoff originated only from Sandfellsjökull and flowed into the river Skálm. There was no visibility over Mýrdalsjökull to determine which cauldrons the water was coming from.

The volcano remains highly active. Strong vulcanian-type explosions occur almost daily, or even more often.
An eruption this afternoon produced impressive shock waves (visible in the video embedded) and billowing ash plumes rising up to 5-6 km altitude. Several volcanic ash alert messages to aviation have been issued by Tokyo VAAC.
