where was the largest destructive tsunami ever recorded
List of historical tsunamis The deadliest tsunami in recorded history was the 2004 Indian Ocean tsunami, which killed almost 230,000 people in eleven countries. The 365 CE Mediterranean tsunami's death toll may have been much higher.[citation needed]
2011 Tōhoku earthquake and tsunami The earthquake took place at 14:46 JST (UTC 05:46) around 67 km (42 mi) from the nearest point on Japan's coastline, and initial estimates indicated the tsunami would have taken 10 to 30 minutes to reach the areas first affected, and then areas farther north and south based on the geography of the coastline.[127][128] Just over an hour after the earthquake at 15:55 JST, a tsunami was observed flooding Sendai Airport, which is located near the coast of Miyagi Prefecture,[129][130] with waves sweeping away cars and planes and flooding various buildings as they traveled inland.[131][132] The impact of the tsunami in and around Sendai Airport was filmed by an NHK News helicopter, showing a number of vehicles on local roads trying to escape the approaching wave and being engulfed by it.[133] A 4-metre-high (13 ft) tsunami hit Iwate Prefecture.[134] Wakabayashi Ward in Sendai was also particularly hard hit.[135] At least 101 designated tsunami evacuation sites were hit by the wave.[136]
