This assessment of seismic monitoring in the US, by the US Geological Survey, evaluates the existing systems for seismic monitoring and also discusses the advantages and importance of a modernized monitoring system. Furthermore, recommendations are made for an Advanced National Seismic System. In order to incorporate multiple perspectives on seismic monitoring needs and issues, the report was...

The PASSCAL Instrument Center at New Mexico Tech offers support of seismic instrumentation, maintenance of equipment, training, and logistical field support for seismology experiments. The website provides thorough explanations of the sensors, data acquisition systems, and other instrumentation. Researchers can find a users guide, schedules of the instrumentation, and forms to request the use...

The first site for this Topic in Depth comes from the Department of Geological and Mining Engineering and Sciences at Michigan Technological University and is called What Is Seismology? (1). The site describes the basics of seismology, the various types of waves associated with it, and even contains a link that shows you how to make your own P and S waves. Next is the Earthquakes Overview site (2...

As part of the US Geological Survey, the Albuquerque Seismological Laboratory is responsible for installing and maintaining a global network of seismograph stations and collecting and distributing the data produced by these stations. The Live Internet Seismic Server (LISS) Web site provides this data free to the public from over fifty stations around the globe and is updated every 30 minutes. The...

Two new publications from the US Geological Survey (USGS) were posted this month. From the USGS, new probablistic seismic hazard maps for Hawaii are now accessible online. The eight different digital geospatial data sets can be downloaded as ARC/Info, STDS and Metadata files and the maps are in .pdf format.
