Created by the Smithsonian, "this website presents more than 7,000 reports on volcanic activity, provides access to the baseline data and eruptive histories of Holocene volcanoes."
"The goal of the Earth Surface and Interior focus area is to assess, mitigate and forecast the natural hazards that affect society, including earthquakes, landslides, coastal and interior erosion, floods and volcanic eruptions."
"Each IRIS Teachable Moment contains interpreted USGS regional tectonic maps and summaries, computer animations, seismograms, AP photos, and other event-specific information generated within hours of the event and prepared by seismologists and educators.
"SCEC is funded by the National Science Foundation and the U.S. Geological Survey to develop a comprehensive understanding of earthquakes in Southern California and elsewhere, and to communicate useful knowledge for reducing earthquake risk."
"The World-Wide Earthquake Locator aims to provide up-to-date information and detailed dynamic maps of earthquakes and volcanoes across the world. It uses a different cartographic approach putting these natural hazards in the context of human geography. This website also links to a database of past earthquakes and volcanoes."
The Earthquake Hazard Program "monitors and reports earthquakes, assess earthquake impacts and hazards, and research the causes and effects of earthquake."
