The Great East Japan Earthquake of 2011 was the most powerful earthquake in recorded history in Japan, and it’s the fourth most powerful earthquake ever recorded in the world since modern-day record-keeping began in 1900.
What’s nearly unbelievable is how long this earthquake lasts. The resulting powerful tsunami waves reached heights of an estimated 40.5 meters (133 feet) in Miyako in Tōhoku’s Iwate Prefecture. In the Sendai area, the waves traveled at 435 miles per hour for up to six miles inland.
