Daily gray ash plumes rose 100-700 m above the summit and drifted NW, W, and SW. The lava flows on the SSE and NE flanks did not advance, remaining at 1.8 km and 1.1 ...

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported ongoing ash emissions and unrest at Mayon during 9-16 September. Each day the seismic network recorded 2-38 volcanic earthquakes; one rockfall was detected on 6 September. Sulfur dioxide emissions (SO?) generally averaged 500...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that the eruption at Merapi (on Java) continued during 10-16 September with lava avalanches produced by the active lava dome on the upper SW flank. The seismic network recorded as many as 43 lava avalanches that traveled as far as 2...

The Servicio Geologico Colombiano (SGC) reported intensifying eruptive activity at Purac� during 10-15 September. Signals associated with fluid movement dominated the seismicity and were characterized as tremor-type signals located beneath Purac� volcano at depths less than 1 km. Seismic activity as...

The Observatorio Vulcanol�gico y Sismol�gico de Costa Rica-Universidad Nacional (OVSICORI-UNA) reported that a total of 67 small phreatic eruptions at Rinc�n de la Vieja were recorded daily by the seismic and infrasound networks during 6-16 September. One of the eruptive events at 1032 on 6 Septembe...

The Instituto Geof�sico del Per�?s (IGP) Centro Vulcanol�gico Nacional (CENVUL) reported continuing eruptive activity at Sabancaya during 7-13 September. The seismic network detected 41 seismic events associated with the movement of magmatic fluids, along with earthquakes indicating internal rock fr...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that activity continued at Semeru during 10-16 September, with daily eruptive events recorded by the seismic network.
