SI/USGS Google Earth Volcano Layer

Take a trip to your favorite volcano – right from your computer!!! 
Smithsonian Global Volcanism Program data for known or inferred Holocene volcanoes are now available as a Google Earth layer, displaying a photo (when available), geographic data, and links to more detailed information from the GVP and international volcano observatories or other websites focusing on [...]

Ubinas, Peru

Based on pilot reports, the Buenos Aires VAAC reported that ash plumes from Ubinas rose to altitudes of 5.5-7 km (18,000-23,000 ft) a.s.l. and drifted NE and SW during 24-25 December.

Tungurahua, Ecuador

IG reported that although visual observations were occasionally limited due to cloud cover, ash-and-steam and ash plumes from Tungurahua were observed and rose to altitudes of 6-8.5 km (19,700-28,000 ft) a.s.l. during 19-25 December. Plumes drifted SE, SW, and WNW. Ashfall was reported in areas to the SW, W, NW, and N. Roaring noises and [...]

Mount St. Helens, Washington, USA

Data from deformation-monitoring instruments indicated that during 19-25 December lava-dome growth at Mount St. Helens continued. Seismicity persisted at low levels, punctuated by M 1.5-2.5, and occasionally larger, earthquakes. Clouds occasionally inhibited visual observations.

Soufriére Hills, Montserrat, West Indies

MVO reported that during 17-24 December the lava dome at Soufrière Hills changed very little, based on visual observations. Seismic activity was very low and low-level rockfall activity continued. Fumarolic activity on the N and E flanks of the dome continued. The Alert Level remained elevated at 4 (on a scale of 0-5).

Pacaya, Guatemala

According to CONRED, a 17 December INSIVUMEH report noted changes in Pacaya’s behavior. On 19 December, CONRED issued a bulletin noting that INSIVUMEH reported observations of white and blue “smoke” plumes. The plumes rose to an altitude of 2.8 km (9,200 ft) a.s.l. and drifted S. Lava flows were unchanged from previous days. Based on [...]

Kilauea, Hawai’i, USA

Based on overflights and web camera views, HVO reported that fissure segment D from Kilauea’s 21 July fissure eruption continued to feed perched lava ponds within a lava flow that frequently overflowed their channel edges during 19-25 December. Lava flowed from the base and top of the Thanksgiving Eve Breakout (TEB) shield, and crust overturned [...]
