High-resolution digital elevation dataset for Glacier Peak and vicinity, Washington, based on lidar surveys of August-November, 2014 and June, 2015 High-resolution digital elevation dataset for Glacier Peak and vicinity, Washington, based on lidar surveys of August-November, 2014 and June, 2015
Glacier Peak is a 3,214 m (10,544 ft.) stratovolcano composed mainly of dacite. The volcano is located in the Glacier Peak Wilderness Area, in the Mt. Baker-Snoqualmie National Forest, about 100 km (65 mi) northeast of Seattle and 110 km (70 mi) south of the International Boundary with Canada. Since the continental ice sheets receded from the region approximately 15,000 years ago...
Differential Optical Absorption Spectroscopy data acquired at Sabancaya Volcano (Peru) on 21 May 2016 Differential Optical Absorption Spectroscopy data acquired at Sabancaya Volcano (Peru) on 21 May 2016
On 21 May 2016, two Differential Optical Absorption Spectroscopy (DOAS) instruments were used to measure the radiance of scattered solar radiation passing through the plume emitted from Sabancaya Volcano, Peru. Spectra were recorded in the ultraviolet (UV: 280 425 nm) and visible (Vis: 450 780 nm) wavelength ranges at 0.6 and 1.2 nm resolution, respectively. Two distinct experiments were
Volcanic Gas Measurements at Mount Cleveland, 14-15 August 2015 Volcanic Gas Measurements at Mount Cleveland, 14-15 August 2015
Helicopter-based, upward-looking differential optical absorption spectroscopy (DOAS) measurements of scattered solar ultraviolet radiation and Multi-Component Gas Analyzer System (Multi-GAS) measurements of trace gas concentrations were made while traversing beneath and through the gas plume emitted from Mount Cleveland volcano on 14-15 August, 2016. Radiance spectra and gas compositions...
Digital Database and Maps of Quaternary Deposits in East and Central Siberia Digital Database and Maps of Quaternary Deposits in East and Central Siberia
This digital database is the product of collaboration between the U.S. Geological Survey, the Alfred Wegener Institute for Polar and Marine Research Potsdam, Foothill College GeoSpatial Technology Certificate Program, and the Geophysical Institute at the University of Alaska. The primary goal for creating this digital database is to enhance current estimates of organic carbon stored in...
Data from debris-flow run-up experiments conducted in June, 1994, and May, 1997, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon Data from debris-flow run-up experiments conducted in June, 1994, and May, 1997, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon
The data files consist of four .csv files, with one file for each of four experiment dates (1994_06_21, 1994_06_23, 1997_05_20, and 1997_05_22). Each file contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity (flow depth, h, flow speed, u, or run-up height, H) measured at that time. Detailed descriptions of column...
High-resolution digital elevation dataset for Newberry Volcano and vicinity, Oregon, based on lidar survey of August-September, 2010 and bathymetric survey of June, 2001 High-resolution digital elevation dataset for Newberry Volcano and vicinity, Oregon, based on lidar survey of August-September, 2010 and bathymetric survey of June, 2001
Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level. It is the product of deposits from thousands of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry...
Subscribe to Volcano Notification Services Subscribe to Volcano Notification Services
The Volcano Notification Service (VNS) is a free service that sends you notification emails about volcanic activity happening at U.S. monitored volcanoes. You can customize the VNS to deliver notifications for certain volcanoes or a range of volcanoes, and you can also choose the notification types you want to receive. Notifications are issued by the five U.S. Volcano Observatories.
Volcano Monitoring Data Volcano Monitoring Data
Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.
