Sakurajima volcano (Kyushu, Japan): stronger and more than usual frequent explosions
Wednesday Jul 25, 2012 11:05 AM | BY: T
Sakurajima volcano continues to be particularly active. The volcano, known for its persistant svulcanian type eruptions, typically 1-2 per day, has been having more than usual frequent and stronger explosions during the past months.
A powerful eruption occurred last evening a recent youtube video shows. The explosion occurred not from the normally active Showa-dake, but the less frequently active Minami-dake crater, and the explosion showered the flanks of the volcano with hundreds of blocks up to considerable distance. An ash column can be seen rising several kilometers.
Today, several explosions occurred as well with ash plumes reported up to 10,000 ft (ca. 3 km) altitude, the Tokyo VAAC reported.

A large M6.6 earthquake occurred on or near Simeulu Island, west of Sumatra, Indonesia. Preliminary data from USGS indicate a magnitude of 6.6 and an epicenter depth of about 45 km. The quake is located approx. 100 km east of the Sunda trench marking the subduction of the Indo-Australian under the Southeast Asian lithospheric plate. [more]

Volcanic activity world-wide 28 June 2012: Eruption warning for El Hierro, updates for Colombia and Mexico
Thursday, Jun 28, 2012
The intense seismic swarm at El Hierro volcano continues with more than 100 quakes > M1.5 so far today. The quakes are concentrated underneath the El Julan coast, and some of the most recent quakes today have been at significantly shallower levels, 15-17 km, and indicate that magma now has started to rise. ...

The most interesting volcano-related event at the moment is certainly the seismic crisis on El Hierro where the high-intensity earthquake swarm accompanied by tremor episodes continues. The quakes, still at "safe" 20 km depth, have now migrated to the El Julan coast where magma could be accumulating. ... [more]

A new eruption might be under way at El Hierro (Canary Islands, Spain). Following several weaker swarms in the past weeks, a strong swarm started late on 24 June and increased dramatically to more than 200 earthquakes of M1.5 or more, including volcanic tremor. The quakes locations indicated that magma was moving at depth from N towards the S in a similar way as at the start of the 2011 submarine eruption. Therefore, the possibility of renewed eruptive activity is real. ... [more]
