TextThis report on the status of Kilauea volcanic activity, in addition to maps, photos, and Webcam images (available using the menu bar above), was prepared by the USGS Hawaiian Volcano Observatory (HVO). Hawai`i Volcanoes National Park status can be found at www.nps.gov... or 985-6000. All times are Hawai`i Standard Time. KILAUEA VOLCANO (CAVW #1302-01-) 19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m) Current Volcano Alert Level: WATCH Current Aviation Color Code: ORANGE Activity Summary for past 24 hours: Back-to-back DI events continued with the most recent DI inflation at 8 pm last night and the summit lava lake rose with tilt. At Pu`u `O`o, incandescence was visible from sources on the crater floor and on the southeast flank. Lava flows were presumed active southeast of Pu`u `O`o although no satellite images were available. Seismic tremor levels were low and gas emissions were elevated. Past 24 hours at Kilauea summit: Back-to-back DI events continued: the summit tiltmeter network recorded mini-DI inflation at 8 pm last night and the lava lake level started to rise immediately. The summit GPS network recorded line length changes that mimicked the tilt superimposed on very weak extension since late October. A small amount of ash-sized tephra, mostly fresh spatter, was wafted within the gas plume from the summit vent and deposited on nearby surfaces. The most recent (preliminary) sulfur dioxide emission rate measurement was 700 tonnes/day on November 23, 2011.
Ford Cochran says that the 500 or so tremors in and around the caldera of Katla just in the last month suggest "an eruption may be imminent"
NASA's Landsat satellites have been tracking Yellowstone's underground geothermal activity, a deep heat that is stored 4,000 miles into the earth's core. But there are areas where these energy levels are becoming erratic. Old Faithful could be in trouble.
Up until recently, the heat coming from Yellowstone's underground magma chamber has always been the fuel for over 10,000 of the volcano's features: Old faithful, hot springs, geysers, mud spots, terraces and mud pots. But NASA is reporting that the Landsat imagery has picked up some unexpected developments outside the park's borders, also picked up by energy companies beyond the park's borders.
"If that geothermal development outside of the park begins, we need to know whether that's going to cause Old Faithful to suddenly stop spewing," says Rick Lawrence of Montana State University.
