It is one of the memories that some wish they had never experienced. It killed more than 230,000 people, including 95 French people, destroyed the coasts of 13 countries and left thousands destitute. Fifteen years have passed and yet no one has forgotten the 2004 tsunami on the coasts of the Indian Ocean. December 26, 2004, 9:30 a.m. Hundreds of tourists lounge by the swimming pools of luxury hotels in Thailand. Some are having breakfast, others are finishing getting ready before going on an excursion. They are far from imagining that in a few minutes, nothing will remain of these heavenly places. Deep in the ocean, a cataclysm is brewing.
