April 1, 1946: The April Fools tsunami, triggered by an earthquake in Alaska, killed 159 people, mostly in Hawaii. July 9, 1958: Regarded as the largest recorded in modern times, the tsunami in Lituya Bay, Alaska was caused by a landslide triggered by an 8.3 magnitude earthquake.
After the 2004 Tsunami, Thailand created a tsunami evacuation system with alarm towers along the coast, plus radio, television, and text message warnings and clearly marked evacuation routes in densely populated areas. The April 2012 tsunami warning triggered by an earthquake in Indonesia was an excellent test of the system. Though ultimately there was no massive tsunami, at least in Thailand all potentially affected areas were evacuated quickly.
