Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System
Five Data Collection Platforms (DCP) were integrated electronically with thermall sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites. The DCP's transmitted 3260 messages comprising 26,080 ambient, surface, and near-surface temperature records at an accuracy of ±1.15 °C for...Preble, Duane M.; Friedman, Jules D.; Frank, David
The Fars, Iran, earthquake of April 10, 1972--results of a field reconnaisanceDewey, James W.; Grantz, Arthur
At 11:43 HST, Civil Air Patrol flight CAP20 reported plume tops at about 9,500 ft with the dispersed plume rising as high as 11,000 ft. The CAP mission was launched from Hilo in support of Hawai‘i County Civil Defense and USGS Hawaiian Volcano Observatory response to the ongoing eruption. Ash from this plume was reported falling on communities downwind. Information on ash hazards and how to...
At 11:05 a.m. HST. Photograph from the Jaggar Museum, Hawai`i Volcanoes National Park, captures an ash plume rising from the Overlook crater. Ash falling from the plume can be seen just to the right side (and below) the plume.
At 1:38 p.m. HST, another dark ash plume rose from the Overlook crater. During a flight earlier today by the Civil Air Patrol, the height of the ash plumes near the crater rose to more than 3 km (9,800 ft) above sea level, and downwind the plumes continued to rise to about 3.5 km (11,500 ft) above sea level.
USGS Hawaiian Volcano Observatory status of Kilauea volcano in Hawaii on May 15, 2018.
USGS Hawaiian Volcano Observatory status of Kilauea volcano in Hawaii on May 14, 2018 by scientist in charge Tina Neal.
At 8:44 a.m., HST. Aerial view of the active ‘a‘ā flow spreading from fissure 17 (the fissure's low ...
At 2:30 p.m. HST, the flow front of Fissure 17 continues down slope. The barren, brown area to the right in the photograph is a lobe of the Kii Flow from the eruption of 1955. The Fissure 17 flow front is located approximately .7 miles makai of Highway 132 and is 1.4 miles mauka of Hwy 137.
Aerial view of fissure 17 around 4:30 p.m. HST. On the west end of the flow, intermittent percussive jetting threw spatter and lava bombs up to 500 feet above the ground. East margin of the ‘a‘ā flow was cascading into a pit or graben.
MENLO PARK, California — Los teléfonos móviles y otros dispositivos electrónicos personales podrían ayudar en las regiones donde se encuentran en uso generalizado, y pueden funcionar como sistemas de alerta para terremotos mayor según la nueva investigación científica recien publicada.
A new California earthquake forecast by the U.S. Geological Survey and partners revises scientific estimates for the chances of having large earthquakes over the next several decades.
Reactivated faults that have produced thousands of Oklahoma earthquakes are capable of causing larger seismic events, according to U.S. Geological Survey research published today in Geophysical Research Letters.
MENLO PARK, Calif.— A paper published today in Science provides a case for increasing transparency and data collection to enable strategies for mitigating the effects of human-induced earthquakes caused by wastewater injection associated with oil and gas production in the United States.
RESTON, Va.-- Aftershocks from the 2011 Virginia earthquake have helped scientists identify the previously unknown fault zone on which the earthquake occurred.
The President’s fiscal year 2016 budget request for the U.S. Geological Survey is $1.2 billion, an increase of nearly $150 million above the FY 2015 enacted level.
VANCOUVER, Wash. — The large landslide that occurred on March 22, 2014 near Oso, Washington was unusually mobile and destructive.
While the number of large earthquakes fell to 12 in 2014, from 19 in 2013, several moderate temblors hit areas relatively new to seismicity, including Oklahoma and Kansas, according to the U.S. Geological Survey. Worldwide, 11 earthquakes reached magnitude 7.0-7.9 and one registered magnitude 8.2, in Iquique, Chile, on April 1.
The 2011 east coast earthquake felt by people from Georgia to Canada likely originated from a fault “junction” just outside of Mineral, Virginia, according to new U.S. Geological Survey research published in the Geological Society of America’s Special Papers.
Successfully resolving California’s long-standing water supply and ecosystem restoration conflicts in the Delta depends on sound policy based on the best available science.
