March 11, 2011: Tohoku, Japan Earthquake and Tsunami
Large tsunamis, like the one produced by the magnitude 9.0 Tohoku, Japan earthquake on March 11, 2011, can travel across oceans and cause damage on distant shores. In Japan, the earthquake and tsunami displaced more than 500,000 people, caused approximately $232 billion (2015$) in damage and resulted in a nuclear accident. Most of the 18,482 deaths were attributed to the tsunami. Outside Japan there was very little loss of life due to warnings and evacuations, but in the U.S. there was more than $91 million in damage and one death.

March 27, 1964: Great Alaska Earthquake and Tsunamis
NOAA’s National Tsunami Warning Center was established because of the tsunamis produced by the March 27, 1964 earthquake in Alaska’s Prince William Sound. This is the largest recorded earthquake in U.S. history (Mw 9.2) and the second largest in world history. The tsunamis devastated coastal communities in Alaska and caused approximately $1 billion (2015$) in damage along the west coasts of the United States and Canada and in Hawaii. More than 130 people died in Alaska, Oregon and California due to the earthquake and tsunamis. http://ntwc.arh.noaa.gov/ https://youtu.be/Lac4Zs_CIdw

April 1, 1946: Unimak Island, Alaska Earthquake and Tsunami
NOAA’s Pacific Tsunami Warning Center is largely a result of the tsunami produced by the Mw 8.6 earthquake off Alaska’s Aleutian Islands on April 1, 1946. The tsunami was observed throughout the Pacific. Most of the 167 lives lost and $317 million (2015$) in damage were in Hawaii where wave heights reached 56 feet. http://ptwc.weather.gov/ https://youtu.be/gcaR7tDKlq8

April 3, 1868: Hawaii Earthquake and Tsunami
NOAA’s Global Historical Tsunami Database has information about tsunami events from 2000 BC to the present. Today in tsunami history, April 3, 1868, a large earthquake off the island of Hawaii generated a tsunami that washed away 108 homes and drowned 47 people on the island.

May 22, 1960: Puerto Montt, Valdivia, Chile Earthquake and Tsunami
Most tsunamis are caused by large undersea earthquakes like the one that struck off the coast of southern Chile on May 22, 1960. This quake, the largest ever recorded (Mw 9.5) produced a tsunami that was observed around the world. Devastation was greatest in Chile where loss of life may have exceeded 5,000. Lives were also lost in Japan (139), Hawaii (61), the Philippines (21), and California (2). Worldwide, damage was estimated at $8 billion (2015$). https://youtu.be/mLKNv6a1EbE
