Fossils, rock fractures and erosion are all evidence of changes in land forms. Scientists are now using satellite data also to provide further evidence of land changes on the Earth.
According to the Science Daily, scientists have been able to use satellite data to detect the changes in the earth's surface caused by a massive earthquake. Research shows a clearer picture of how the earth changed after the December, 2004 Sumatra-Andaman earthquake, the 9.1-magnitude temblor in the Indian Ocean which caused a deadly tsunami killing nearly 230,000 and displacing more than 1 million people.
