Volcanos

Roundup of Global Volcanic Activity:

Sakurajima (Kyushu, Japan): Strong activity continues. This morning, a relatively large vulcanian-type explosion produced a plume rising to 14,000 ft (4.3 km) altitude. The the volcano continued to emit ash for several hours following the explosion.

White Island (New Zealand): GeoNet issued a new bulletin about unusual seismic activity at White Island, but mentions that there is no current eruption: "Over the past few weeks White Island has repeatedly produced very small volcanic earthquakes. These small tremor bursts are occurring like clockwork, approximately every 70 seconds, creating a unique pattern on our earthquake drum, with hundreds of these small bursts recorded every day."

Popocatépetl (Central Mexico): Activity increased again a few hours ago. Strong tremor and near continuous emissions as well as bright glow from the summit can be seen on the current seismogram and on webcams.

San Diego (Colombia): (9 Jul) On 5 July 2013, Colombian scientists from INGEOMINAS have installed a first seismic monitoring station in order to find out whether San Diego volcano is potentially still active or not.
