Here is a satellite image acquired January 7, 2011, showing the flooding at Rockhampton, Queensland, Australia. The flooding from the Fitzroy River can be seen throughout the city and adjacent countryside. You can barely make out one of the runways at the airport as the rest of the airport is shown underwater.
The NASA Earth Observations website has dozens of layers of global scientific data formatted for viewing with Google Earth.
The data is grouped into Ocean, Atmosphere, Energy, Land and Life categories. The layers are too numerous to list, but they include:
Sea Surface Temperature Chlorophyll Concentration (MODIS) Snow Cover & Sea Ice Extent [...]
On Tuesday, January 12, 2010 at 4:53 PM, a 7.0 magnitude earthquake struck near Port-Au-Prince, Haiti. Relief agencies and scientific agencies from all over the world have been compiling maps and other data to aid in relief efforts. Over the last several days I’ve been trying to help compile maps and other GIS data [...]
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 [...]
USGS ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes throughout the world. The maps show the epicenter of the earthquake and are color coded to show relative ground motion.
Individual maps are created for each earthquake event. Unfortunately, the maps must be accessed via their website. But I [...]
This collection of earthquake data displays large magnitude (6.5 and above) earthquakes dating back to 1900. Each earthquake is represented by a colored circle located at the approximate location of the epicenter. The color of the circle represents the number of fatalities and the size of the circle represents the the magnitude of the [...]
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 [...]
FEMA has two applications to display various flood related data in Google Earth.
Stay Dry – This is the simpler of the two applications. When you start Stay Dry, you’ll see an overview map of the US that shows which areas of the country have coverage available. If the area you are interested [...]
