A team of scientists from China, U.S. and Mexico has used light detection and terrestrial elevation using laser (LIDAR) to study how earthquakes change landforms. Using this technique, seismologists can pinpoint the places where the crust was broken and the data thus obtained could be used to estimate the probability of earthquakes in certain areas.
If this technique could be applied in regions with high risk of producing earthquakes, workers could find out if there is a tendency of occurrence of earthquakes in the near future. Population and local authorities would have the time to prepare to face event.
Researchers have made very precise topographic images of a seismic zones in Mexico, before and after a major earthquake (7.2 magnitude earthquake degrees from the He-Cucapah Mayor of April 4, 2010), which caused a rift in the earth’s crust length of 120 km.
The region was mapped using a lidar system, which sends a series of laser beams to the ground, with uneven surface which can be measured with precision of centimeters. In only three days, could be thus achieved a 3D topographic map of a surface area of 360 square kilometers. The experts then compared the data obtained with another set of data previously collected in 2006 with the help of lidar systems, noting changes, arrangement of faults and the occurrence of cracks in the crust here extracting conclusions on the likelihood of further earthquakes in the future .
