SUMMARY
December 26 marks 15 years since a 9.1 magnitude quake off the coast of Indonesia's Aceh province triggered a tsunami that killed more than 230,000 people in Indonesia, Sri Lanka, India, Thailand and nine other countries. When the quake opened a faultline deep beneath the Indian Ocean, it triggered a wave as high as 17.4 meters (57 feet), wiping some communities off the map in seconds.
