Tsunamis have been some of the most devastating natural disasters in history, causing massive loss of life and property. This article the data of the top dangerous tsunamis over the last 300 years, detailing the year and month they occurred, the affected country, the ocean involved, the earthquake’s magnitude on the Richter scale, the number of casualties, and the reason behind the tsunami.

Significant events include the 1700 Cascadia Subduction Zone earthquake causing an orphan tsunami in Japan, the 1755 Lisbon earthquake leading to a catastrophic tsunami in Portugal, and the notorious 1883 Krakatoa eruption in Indonesia. Other notable tsunamis include the 1960 Valdivia earthquake in Chile, the most powerful recorded earthquake at a magnitude of 9.5, and the 2004 Indian Ocean earthquake, which claimed over 230,000 lives across multiple countries. More recent events include the 2011 Tohoku earthquake in Japan, resulting in nearly 16,000 deaths, and the 2018 Sulawesi earthquake in Indonesia. Please note that some numbers of casualties are approximate values.

For more detailed information on these and other tsunamis, various online resources such as the US Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), and the International Tsunami Information Center (ITIC) offer comprehensive data and analyses. These sources provide invaluable insights into the history, causes, and impacts of tsunamis worldwide.
