Suwanose-jima (Ryukyu Islands): The activity of the volcano has become more intense during the past days. Several ash plumes were detected by Tokyo VAAC and blight glow is intermittently visible on the webcam.
Most likely, the volcano has started another phase of intense, intermittent strombolian explosions.
Semeru (East Java, Indonesia): Access to the mountain was closed after a 26 year-old Swiss climber has been missing for 10 days now since he climbed the volcano on 3 June.
The young man who climbed the volcano without a guide was reported missing by a travel companion who had been in a different location for a few days and could notice his absence only 3 days later. Despite intense efforts, local search-and-rescue teams have so far been unsuccessful to locate the young man. It can only be speculated about his fate, but chances of his survival seem dwindling.
The most likely causes for the accident are lost orientation on the mountain during ascent or descent, or perhaps falling into one of the difficult-to-access steep ravines draining on the volcano’s steep slopes.
Suretamatai (Banks Islands, Vanuatu): The alert level of the volcano (also known as Vanua Lava) was recently raised a notch from 0 to 1 (on a scale of 0-4). No details about volcanic unrest are available, but presumably, the Vanuatu Geohazards Observatory recorded elevated seismic activity from the volcano.
Residents and tourists are reminded to stay outside of areas near the crater and in particular avoid the Sulfur River (E flank) were there is a high risk of volcanic gas emissions.
Popocatépetl (Central Mexico): A moderately strong vulcanian explosion occurred yesterday morning at 11:17 local time, producing a mushroom-shaped ash plume that rose approx. 3 km above the summit and dispersed in westerly directions.
Today, the volcano has been mostly calm with only minor emissions mainly of steam and gas.
The activity of the volcano itself has been very stable over the past months and at overall low to medium levels only; while lava is slowly accumulating in the summit crater, this growth of the lava dome is occasionally interrupted by explosions such as this one.
