Assoc. Prof. Dr. Panya Jarusiri from the Department of Geology, Faculty of Science, Chulalongkorn University, confirmed to the ASTV Manager Online science desk that Phuket would not sink under the waves any time soon. The island sits on a base of solid stone that has lasted for more than 100 million years and is more than strong enough to withstand earthquakes. The series of rapid aftershocks is simply a natural post-earthquake phenomenon, and their shallow depths are the reason why people on the surface are feeling the tremors.
