DNA: Dynamic North America Models The DNA models are a series of 3D tomographic velocity models of the North American Continent. The models make use of the Earthscope geophysical datasets as well as the permanent regional geophysical networks and short-term deployments. As the USArray Transportable Network rolls across the continent the additional data will be incorporated into these models. more...

Cascadia: Structure, slip and process
Mendocino		Building on the OATS study, two new Earthscope deployments in Cascadia are designed to study episodic tremor and slip, constrain the interaction between the subducting Juan de Fuca plate and the overriding North American continent, and map the formation of the San Andreas Fault system. more...FACES | more...Mendocino Slow slip of the subduction interface in Cascadia, accompanied by seismic tremor, occurs periodically on different segments of the Cascadia subduction zone. From 2000 to 2006 twenty two tremor and slip events occurred, an average of one every 3.3 months. more...

ElarmS: Earthquake Alarm Systems ...also visit: www.ElarmS.org ElarmS is a suite of algorithms designed to (1) rapidly detect the initiation of an earthquake, (2) determine the size (magnitude) and location of the event, (3) predict the peak ground motion expected in the region around the event, and (4) issue a warning to people in locations that may expect significant ground motion. more...
