Lisbon Earthquake Portugal
the earthquake almost totally destroyed Lisbon and adjoining areas. Seismologists today estimate the Lisbon earthquake had a magnitude in the range 8.5–9.0 on the moment magnitude scale, with its epicenter in the Atlantic Ocean about 120 miles west southwest of Cape St. Vincent. Estimates place the death toll in Lisbon alone between 10,000 and 100,000 people, making it one of the deadliest earthquakes in history. -
Krakatoa Eruption (Java/Sumatra)
over 70% of the island and its surrounding archipelago were destroyed as it collapsed into a caldera.The 1883 eruption was one of the deadliest and most destructive volcanic events in recorded history. At least 36,417 deaths are attributed to the eruption and the tsunamis it created. Significant additional effects were also felt around the world in the days and weeks after the volcano's eruption. -
Aleutian Earthquake (Alaska)
The shock had a moment magnitude of 8.6 and a maximum Mercalli intensity of VI (Strong). It resulted in 165–173 casualties and over $26 million in damage. The seafloor along the fault was elevated, triggering a Pacific-wide tsunami with multiple destructive waves at heights ranging from 45–130 ft. -
Great Chilean Earthquake (Chile)
Great Chilean earthquake of 22 May is the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale. It occurred in the afternoon, and lasted approximately 10 minutes. Over 1000 to 7000 people died -
Good Friday Earthquake (Alaska)
a mega thrust earthquake struck Alaska, The quake had a moment magnitude of 9.2, making it the second most powerful earthquake ever recorded. The initial quake and subsequent underwater landslides caused numerous tsunamis, which inflicted heavy damage on the coastal towns of Valdez, Whittier, Seward, and Kodiak. Over 139 people died. -
Hokkaido Earthquake (Japan)
It had a magnitude of 7.7 on the moment magnitude scale and a maximum felt intensity of VIII (Severe) on the Mercalli intensity scale. It triggered a major tsunami that caused deaths on Hokkaidō and in southeastern Russia, with a total of 230 fatalities recorded. The island of Okushiri was hardest hit, with 165 casualties from the earthquake, the tsunami and a large landslide. -
Papua New Guinea Quake
had a moment magnitude of 7.0 and a maximum Mercalli intensity of VIII (Severe). The event occurred on a reverse fault near the north coast region of Papua New Guinea, 25 kilometers (16 mi) from the coast near Aitape, and caused a large undersea landslide which caused a tsunami that hit the coast, killing between at least 2,183 and 2,700 people and injuring thousands. -
Sumatra Earthquake
an undersea earthquake with a magnitude of 9.1 struck off the coast of the Indonesian island of Sumatra. Over the next seven hours, a tsunami a series of immense ocean waves triggered by the quake reached out across the Indian Ocean, devastating coastal areas as far away as East Africa. Some locations reported that the waves had reached a height of 30 feet or more when they hit the shoreline.The tsunami killed at least 225,000 people across a dozen countries -
Samoa Earthquake
The submarine earthquake occurred in an extensional environment and had a moment magnitude of 8.1 and a maximum Mercalli intensity of VI. 189 died in this earthquake. -
Chile Earthquake
having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. 525 people died. -
Tohoku Earthquake
a magnitude 9.0–9.1 undersea megathrust earthquake off the coast of Japan. over 15,896 deaths, 6,157 injured, 2,537 people missing.
