The magnitude of the earthquake was between 8.5-9.0 M. The estimated death toll was an estimated 50,000 to 90,000 people. It caused a tsunami that reached across the Atlantic. Went as far as Brazil. It triggered modern disaster science, it was the first to be studied. -
The magnitude of the volcano was VEI of 6. The estimated death toll was 36,000 to 40,000 people. The island partially disappeared and later regrew, a volcano emerged. It dramatically affected the global climate. Global temp dropped about 1.2 degrees C (2.2 degrees F). -
The magnitude of the Earthquake was 8.6M. The estimated death toll was 165 people. It sparked the first Pacific-wide tsunami warning system in 1949. It affected areas far beyond Alaska and Hawaii, reached the Philippines and South America. -
The magnitude of the earthquake was 9.5M. The estimated death toll was 1,000 to 6,000. It was the most powerful earthquake ever recorded. It also generated a massive Pacific-wide tsunami, reaching New Zealand. -
The magnitude of the earthquake was 9.2M. The estimated death toll was 131. It changed the river directions and fish habitats. It reshaped Alaska's landscape dramatically. -
The magnitude of the earthquake was 7.7M. The estimated death toll was 230 to 240. It caused a major oil spill - not from sea, but from land. It momentarily slowed down Earth's rotation - ever so slightly. -
The magnitude of the earthquake was 7.0 - 7.1M. The estimated death toll was 2,200 to 2,500. Some quakes there caused volcanoes to "wake up." Deadly tsunamis triggered by submarine landslide, rather than earthquake slip. -
The magnitude of the earthquake was 9.1-9.3M. The estimated death toll was 230,000 to 280,000. It made the entire Earth shake like a bell, seismic waves rippled around the planet for weeks. Animals sensed the disaster before the humans. -
The magnitude of the earthquake was 8.1M. The estimated death toll was 189 to 200. Two nearly simultaneous earthquakes rather than a single one happened. It intensified the sea-level rise. -
The magnitude of the earthquake was 8.8M. The estimated death toll was 525 to 600. A lake disappeared and another was born. It helped scientists confirm global seismic wave behavior. -
The magnitude of the earthquake was 9.0M. The estimated death toll was 15,899. It caused the Fukushima nuclear disaster. It moved Japan's landmass closer to North America. -
The magnitude of the earthquake was 7.5M. The estimated death toll was 4,340. A soil liquefaction swallowed an entire neighborhood, or neighborhoods. The Palu-Koro fault had unusually complex rupture behavior.
