The Cooperative Institute of Meteorological Satellite Studies at the University of Wisconsin-Madison Space Science and Engineering Center (CIMSS-SSEC) has created a huge set of weather related overlays that can be viewed in Google Earth.
Their program is focused on tropical cyclones, but they also have a large amount of satellite and other data [...]
The Advanced Very High Resolution Radiometer (AVHRR) sensor collects cloud and other data from several satellites orbiting the Earth. The University of Wisconsin has created an archive of AVHRR false color imagery dating back to 2007. In addition, they have created a network link that updates automatically every day with the most recent satellite [...]
The USGS Earthquake Hazards Program has compiled a database of earthquake faults in the United States which are believed to be the sources of earthquakes with magnitudes greater than 6 during the past 1,600,000 years. Detailed descriptions of many of the faults is provided via an online database linked to the fault lines in [...]
Highly detailed digital geologic maps of the US states (not including Alaska and Hawaii) with consistent descriptions (lithology, age, etc) from state to state. The original geologic data was from various sources and compiled by the USGS into KML format.
Click on a polygon to bring up information about that geologic unit. From [...]
The Mineral Resources Data System was compiled by the USGS and describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references for each location. The dataset includes information on over 300,000 locations throughout the Earth.
These are large files [...]
Global database created by the National Geophysical Data Center which shows the locations of historic natural hazards, including earthquakes, tsunamis, and volcanic eruptions. The database includes socioeconomic information (i.e. number of fatalities, injuries, and damage information) and scientific data (i.e. earthquake magnitudes, tsunami intensity) for hazard events dating back to before 2000 BC. The [...]
