Stopping stick-slip seismic events?

This resource provides an abstract. This study models underground frictional resistance in stick-slip seismic events in order to determine the amount of energy needed to weaken a fault plane enough ...

Using GPS for earthquake imaging

This resource provides an abstract. The authors used a dense array of Global Positioning System (GPS) stations to model how the Earth slipped during the 2003 8.0-magnitude Tokachi-Oki earthquake near ...

3-D Simulations of Magnitude 7.1 Earthquakes Along the Hayward Fault

This set of simulations presents the results of simulated ground motions in the San Francisco Bay Area due to earthquakes of Magnitude 7.1 along the Hayward fault. Three rupture scenarios are ...

Crustal structure and tectonics from the Los Angeles basin to the Mojave Desert, southern California
A seismic refraction and low-fold reflection survey, known as the Los Angeles Region Seismic Experiment (LARSE), was conducted along a transect extending from Seal Beach, California, to the Mojave ...

Misconception of energy release in earthquakes
Analyzes how textbooks define and describe an earthquake focus or hypocenter. Provides examples from textbooks that reflect an absence of precision in words and diagrams that can foster ...

Scent of a myth: tectonics, geochemistry and geomythology at Delphi (Greece)
Extensive geochemical investigation (of water, travertine, soil and diffuse gas), coupled with geo-structural analysis, provides new insights into local fault-fluid interaction and allows us to ...

Rainfall-induced lahars in the Belham Valley, Montserrat, West Indies
Rain falling on loose volcanic debris over the Soufriere Hills Volcano, Montserrat generates hazardous floods in the Belham Valley. These rainfall-induced lahars vary greatly in discharge and ...

Users can access a selection of technical information and data about earthquakes in the U.S. and around the world. A current worldwide list of earthquakes is available, as are data on geophysical ...

International Volcanic Health Hazard Network

This international organization collects and disseminates geologic and medical data to evaluate and predict volcanic health hazards. The site provides an index of members working in the fields of ...

The Cataclysmic 1991 Eruption of Mount Pinatubo, Philippines

This United States Geological Survey (USGS) on-line publication highlights the events and aftermath of the June 15, 1991 eruption of Mt. Pinatubo in the Philippines, which was the second-largest ...

Geological Survey of Canada, Geodynamics Program: Earthquake Processes: Cascadia Subduction Zone

This page explains the tectonic setting of the west coast of North America. It explains the process of the subduction of the Juan de Fuca plate beneath the North American plate. It describes the ...

Long-lasting Eruption of Kilauea Volcano, Hawai`i Leads to Volcanic-Air Pollution

In 1986 the eruption of Kilauea Volcano changed from the episodic fountaining of lava and gas at Pu`u O`o cone every few weeks to the continuous outpouring of lava from a new vent only 3 kilometers ...

United States Geological Survey, Earthquake Hazards Program: Earthquake Research

This site describes the research activities of the Earthquake Hazards Program (EHP) of the United States Geological Survey (USGS). The activities include: borehole geophysics and rock mechanics, ...

Volcano Hazards Fact Sheet: Yellowstone - Restless Volcanic Giant

This U.S. Geological Survey Open-File Report summarizes the Yellowstone volcanic system and its associated hazards. Scientists are studying the Yellowstone region to assess the potential hazards from ...

Volcanic Hazard from Iceland: Analysis and Implications of the Eyjafjallajokull Eruption

This report examines the Eyjafjallajökull eruption in Iceland of April 2010. It provides an integrated analysis covering volcanology, geophysics, meteorology, statistics, engineering, hazard and ...
