Sakurajima (Kyushu, Japan) [2]: 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) [3]: 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) [4]: 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) [5]: (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.
