    The 1877 Iquique earthquake occurred at 21:16 local time on 9 May (0:59 on 10 May UTC). It had a magnitude of 8.5 on the surface wave magnitude scale. It has also been estimated to be a 9 magnitude earthquake. It had a maximum felt intensity of XI (Extreme) on the Mercalli intensity scale and triggered a devastating tsunami. A total of 2,541 people died, mainly in Peru and what is now northernmost Chile, with some deaths also reported from Hawaii and Japan.
  • Russia - Kamchatka Earthquake

    Russia - Kamchatka Earthquake
    Three earthquakes, which occurred off the coast of Kamchatka Peninsula in far eastern Russia in 1737, 1923 and 1952, were megathrust earthquakes and caused tsunamis. They occurred where the Pacific Plate subducts under the Okhotsk Plate at the Kuril-Kamchatka Trench. The depth of the trench at the point of the earthquakes is 7,000–7,500 meters. Northern Kamchatka lies at the western end of the Bering fault, between the Pacific Plate and North American Plate, or the Bering plate.
  • Indonesia - Banda Sea Earthquake

    Indonesia - Banda Sea Earthquake
    The 1938 Banda Sea earthquake occurred in the Banda Sea region on February 1, 1938, and was the ninth largest earthquake in the 20th century. It had an estimated magnitude of 8.5 on the Moment magnitude scale, and intensities as high as VII (very strong). It generated Tsunamis of up to 1.5 metres, but no human lives appear to have been lost.
  • Alaska - Aleutian Islands Earthquake

    Alaska - Aleutian Islands Earthquake
    The 1946 Aleutian Islands earthquake was an earthquake near the Aleutian Islands, Alaska on April 1, 1946. It was followed by a Pacific-wide tsunami. The earthquake was a magnitude 8.6 (originally rated 7.8 but later revised), with its epicenter at 52.8°N, 163.5°W, and focal depth of 25 km. It resulted in 165 casualties (159 people on Hawaii and six in Alaska) and over $26 million in damages. Multiple destructive waves at heights ranging from 45–130 ft occurred.
  • India/China - Assam/Tibet Earthquake

    India/China - Assam/Tibet Earthquake
    The 1950 Assam – Tibet earthquake, also known as the Assam earthquake or Medog earthquake, occurred on August 15, 1950, and had a magnitude of 8.6. The epicentre was actually located near Rima, Tibet. The earthquake was destructive in both Assam and Tibet, and 1,526 people were killed. It was the 9th largest earthquake of the 20th century. It is also the largest known earthquake to have not been caused by an oceanic subduction. Instead, this quake was caused by two continental plates converging.
