GPS and Satellites to help during Earthquake

The Global Positioning System has become integral part of the human life since its introduction. After the revolutionary technology was included in portable devices like smartphones and tablets, millions of users are getting its benefits. The app developers of these devices are also finding news applications of this system and other nations like India, Russia are planning to develop own version of the GPS.

The team of scientists at the University of Iowa in an association with the United States Geological Survey (USGS) has found the way to exploit GPS and satellite data in real time so that fault line of the earthquake can be discovered in less than 24 hours of an earthquake.

This will ensure faster delivery of relief material with better accuracy of the location.  In their study, data from 2014 California earthquake was used to draw a 3D map of movement of ground surface during an event of earthquake. This earthquake of South Napa occurred on August 24 with magnitude of 6.0 on Richter scale.

The traditional instruments like seismometers were used to create the simulations.  The scientists informed that the 3D map of the event will improve the accuracy about the shaking of ground. This can be further used to calculate its impact of infrastructure and the human life.

The 3D map of earthquake helped scientists to understand the complicated event. The GPS and satellite statistics contained very tiny movement of ground due to earthquake. The values were in millimeters to centimeters. A mathematical equation then helped researchers to calculate how much total ground moved with respect to fault plane.
