Arrastra Gulch, Silverton, CO 3D Data Viewer

Airborne electromagnetic and magnetotelluric geophysical surveys were conducted from 2018 to 2019 in Arrastra Gulch along the southern margins of the San Juan and Silverton calderas. This scene provides 3-D data integration combining electromagnetic data, geologic and historical mine mapping, and high-resolution drone imagery.

Seismotectonics of the Eastern Margin of the Australia Plate

The Australia-Pacific margin is an intensely active plate boundary that produces some of the world's most powerful earthquakes, tsunamis, and volcanic eruptions. Explore this interactive geonarrative (Esri storymap).

Pennsylvania Groundwater Watch

Pennsylvania Groundwater Watch provides access to groundwater level data from 108 sites in the USGS Active Groundwater Level Network for Adams, Chester, Montgomery, Philadelphia, and Pike Counties. 

Determining High Groundwater Levels in Massachusetts

A method (commonly referred to as the Frimpter method) was developed in early 1980’s to estimate probable high groundwater levels across Massachusetts. The map and table on the web page linked above provide information on wells in the Massachusetts Observation-Well Network which have been used as index wells.

Seismogram Displays and Information

Real-time seismograms from Global Seismographic Network (GSN) and Advanced National Seismic System (ANSS) stations, and station information for both.

Cascadia Subduction Zone Database

A compilation of published datasets relevant to Cascadia subduction zone earthquake hazards and tectonics.

Seismic Design Data Web Services

Web services produced by the U.S. Geological Survey for calculating parameter values from various seismic design reference documents.

Cone Penetration Testing (CPT) Data

Cone Penetration Testing (CPT) is used to identify subsurface conditions in the upper 100 ft of the subsurface.

Interactive U.S. Fault Map

The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr).

Earthquake Scenarios

A scenario represents one realization of a potential future earthquake by assuming a particular magnitude, location, and fault-rupture geometry and estimating shaking using a variety of strategies.

Generate a SLAB Model

This web application is used for generating a 3D slab model following the procedure of Hayes et al., 2018.
