PHIVOLCS recorded that the activity of the volcano continues with lava fountaining. Lava fountains on the N flank remain active, currently about 500 m long. New vents were observed. A steam plumes rose 2 km above the summit. A volcanic ash is dispersed towards the southwest. Since the 12 January at 13:00 local time the seismic station records 144 volcano-tectonic earthquakes of which 44…

The volcano entered to a period of increased phreatic activity. PHIVOLCS recorded magmatic eruptions on 12 January at 13:00 local time and today on 13 January between at 02:49 to 04:28 local time. An ash plumes reached 55,000 ft (16,800 m) altitude. The magmatic eruption is characterized by lava fountaining accompanied by thunders of lightning. At 14:00 local time yesterday, the sounds of…

During the past week, HVO seismometers recorded 56 small magnitude earthquakes beneath the upper elevations of the volcano. Most earthquakes occurred at shallow depths of less than 5 km (~3 miles) beneath the volcano. Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) measurements show continued slow summit inflation, consistent with magma supply to the…
