A magnitude 7.2 earthquake occurred at 3:40:40 p.m. (local time at the epicenter) on Sunday, 4 April 2010 in Baja California, approximately 75 km south of the Mexico-USA border (or about 100 miles east southeast of San Diego, California). The earthquake occurred at shallow depth (approximately 10 km) along the boundary zone between the [...]
On Saturday, February 27 at 6:34:14 UTC, a magnitude 8.8 earthquake occurred near Maule, Chile. News is just starting to come in so not sure how much damage there will be from this earthquake.
I will start working on a collection of map and earthquake data overlays for Google Earth. I will continue [...]
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 [...]
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 [...]
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 [...]
