Volcanic Activity Reports

Recent Volcano Updates from the U.S. Geological Survey Volcano Hazards Program

Dec 12, 2017 18:36 - Activity Summary: K?lauea Volcano continues to erupt at its summit and from the Pu?u ???? vent on its East Rift Zone. The episode 61g lava flow is still producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The surface of the lava lake at K?lauea?s summit was measured at 37 m (120 ft) below the floor of Halema?uma?u crater this morning. There have been no significant changes in ground deformation or seismicity rates across the volcano. Summit Observations: The lava lake surface was measured at 37 m ...
Dec 11, 2017 21:11 - Low-level unrest continues at Great Sitkin volcano. Nothing of note was observed in seismic data and in mostly cloudy satellite data over the past day.
Dec 11, 2017 21:11 - Unrest at Cleveland volcano is continuing at a low level. No activity observed in satellite images during periods of clear weather. No significant activity was detected by seismic or infrasound sensors during the past day.
Dec 11, 2017 21:11 - Unrest continues at Shishaldin. Activity observed on seismic and infrasound instruments remains elevated and robust steaming was observed in web camera images during periods of clear weather. No activity observed in satellite data over the past day.
Dec 8, 2017 22:30 - The 2016-17 eruption of Bogoslof volcano may have come to an end, and the Aviation Color Code and Volcano Alert Level were both decreased to UNASSIGNED on December 6. AVO only assigns Aviation Color Codes and Alert Levels to volcanoes that have a local seismic monitoring network. Since Bogoslof does not have a local network the alert status is now UNASSIGNED. We cannot say for certain that the volcano has returned to its normal background state, however we are no longer detecting any activity that would be considered to be indicative of unrest. The eruption that began ...
Dec 8, 2017 21:13 - Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal background levels of activity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; and Mount Hood, Mount Jefferson, Three Sisters, Newberry, and Crater Lake in Oregon. Recent Observations: Monitoring systems show that activity at Cascade Range volcanoes remained at background levels throughout the week.
Dec 7, 2017 18:54 - Activity Summary: Mauna Loa Volcano is not erupting. Rates of deformation and seismicity persist above long-term background levels. Observations: Small-magnitude earthquakes continue to occur beneath the volcano. Shallow seismicity was concentrated beneath the summit caldera and upper Southwest Rift Zone, at depths less than 5 km (3 miles) and occurred at the rates that we've been observing during the past few weeks. Additional deeper seismicity (5-13 km or 3-8 miles) was scattered beneath the southeast and west flanks of the volcano. Global Positioning System ...
Dec 3, 2017 01:20 - Earthquake activity decreased at L??ihi during November with HVO recording 5 earthquakes in the vicinity of the volcano.
Dec 3, 2017 01:20 - No significant changes were detected at Hual?lai during the month of November. HVO reports 1 earthquake greater than 13 km (8 miles) depth and 1 earthquake shallower than 13 km (8 miles) in the vicinity of the volcano during the past month. HVO's continuously recording Global Positioning System (GPS) receiver atop Hual?lai recorded no significant deformation.
Dec 3, 2017 01:20 - No significant changes were detected at Haleakal? during the month of November. No earthquakes were recorded in the vicinity of the volcano and the continuously recording Global Positioning System (GPS) instrument atop Haleakal? volcano recorded no significant deformation.
Dec 3, 2017 01:20 - No significant deformation or seismicity occurred during the month of November. HVO recorded 17 earthquakes deeper than 13 km (8 mi) and 4 shallow earthquakes beneath the volcano. A single, continuously recording Global Positioning System (GPS) receiver atop Mauna Kea (operated by NASA?s Jet Propulsion Laboratory) recorded no significant deformation.
Dec 1, 2017 22:33 - Recent work In November, the University of Utah, in collaboration with the University of Texas El Paso and Yellowstone National Park, installed 290 nodal seismometers in around the Upper Geyser Basin (near Old Faithful) in a continuation of a study that started in 2015. The temporary deployment, which lasted several days, was intended to record seismic signals from the various thermal features. Using these signals, seismologists can learn more about the geysers and hot springs in Yellowstone. This year?s study focused on an area called Geyser Hill, which is the ...
Dec 1, 2017 20:58 - Monitored CALIFORNIA VOLCANOES Current Volcano Alert Level: all NORMAL Current Aviation Color Code: all GREEN Activity Update: All volcanoes monitored by CalVO using telemetered, real-time sensor networks exhibit normal levels of background seismicity and deformation. Volcanoes monitored include Mount Shasta, Medicine Lake Volcano, Clear Lake Volcanic Field, Lassen Volcanic Center, Long Valley Volcanic Region, Coso Volcanic Field, Ubehebe Craters, and Salton Buttes. Observations for November 1, 2017 (0000h PST) through November 30, 2017 (2359h PDT): Mt ...
Nov 18, 2017 01:14 - On November 10 and 13 strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes picked up loose volcanic ash erupted during the 1912 Novarupta-Katmai eruption. The resulting resuspended ash cloud extended over Shelikof Strait and Kodiak Island. This phenomenon is not the result of recent volcanic activity and occurs seasonally in the spring and fall during times of high winds and dry snow-free conditions in the Katmai area and other young volcanic areas of Alaska. All of the volcanoes of the Katmai area (Snowy, Griggs, Katmai, Novarupta, Trident, ...
