A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, [1] but are a worldwide natural phenomenon.
The two "mega-disasters" of the 2004 Indian Ocean tsunami and Hurricane Katrina in 2005 inspired the series and provided a reference point for many of the episodes. [1] Excepting only two shows devoted to man-made disasters , the threats explored can be divided into three general categories: meteorological , geological , and cosmic hazards.
The 1935 Labor Day hurricane was the most intense hurricane to make landfall on the country, having struck the Florida Keys with a pressure of 892 mbar.It was one of only seven hurricanes to move ashore as a Category 5 hurricane on the Saffir–Simpson hurricane scale; the others were "Okeechobee" in 1928, Karen in 1962, Camille in 1969, Andrew in 1992, Michael in 2018, and Yutu in 2018, which ...
A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.

The 1674 Ambon earthquake occurred on February 17 between 19:30 and 20:00 local time in the Maluku Islands. The resulting tsunami reached heights of up to 100 metres (330 ft) on Ambon Island killing over 2,000 individuals. It was the first detailed documentation of a tsunami in Indonesia and the largest ever recorded in the country. [1]
The 1867 Virgin Islands earthquake and tsunami occurred on November 18, at 14.45 in the Anegada Passage about 20 km southwest of Saint Thomas, Danish West Indies (now U.S. Virgin Islands). The M s 7.5 earthquake came just 20 days after the devastating San Narciso Hurricane in the same region.
Record ocean warmth during the hurricane season due to climate change made major Hurricanes Helene and Milton stronger, adding 16 to 24 mph respectively, according to the study from the non-profit ...
Most of the casualties and damage were caused by a tsunami affecting the west coasts of Nicaragua and Costa Rica, and it was one of three tsunamis to occur within a span of six months. [8] Runup heights were measured shortly after the earthquake [10] and reached heights of up to 9.9 meters, though the average height was 3 to 8 meters.
