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

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

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

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).

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.

Explore bird banders’ data and learn how many birds have been banded and encountered since 1960. Banding and encounter data are available for request for research purposes. Discover specific banding and encounter data, the number of birds banded per species group, or learn about the lab’s species longevity records.

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures.

Vs30, the time-averaged shear-wave velocity (Vs) in the upper 30 meters, is a key index adopted by the earthquake engineering community to account for seismic site conditions. USGS has compiled measured VS30 funded by the USGS and other governmental agencies for 4389 sites in the United States.

US Geological Survey operates a streamflow monitoring network that extends across the United States and its territories. The network was analyzed systematically by Konrad and others (2022) for its coverage, resolution, and representation of a wide range of public interests in streamflow information The results can be used to identify priority areas for continued or expanded monitoring.
