The 28 September 2018 magnitude 7.5 Palu, Indonesia earthquake (0.178°S, 119.840°E, depth 13 km) occurred at 1002 UTC. The major earthquake triggered catastrophic liquefaction, landslides, and a near-field tsunami that resulted in direct damage, impact, economic loss, and loss of life.
Since 1933, 31 tsunamis have been observed in Crescent City. Four of those caused damage, and one of them, in March 1964, remains the “largest and most destructive recorded tsunami to ever strike the United States Pacific Coast,” according to the University of Southern California’s Tsunami Research Center.
The West Coast states of Washington, Oregon, and California have experienced tsunamis from as far away as Alaska, South America, Japan, and Russia. The most damaging on record is the tsunami caused by the 1964 Great Alaska earthquake.
Where do tsunamis most often occur in the world? Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones.
The 2020 Aegean Sea earthquake, also known as the Samos–İzmir earthquake, occurred on 30 October 2020, with a moment magnitude of 7.0, about 14 km (8.7 mi) northeast of the Greek island of Samos.

You can’t surf a tsunami because it doesn’t have a face. … On the contrary, a tsunami wave approaching land is more like a wall of whitewater. It doesn’t stack up cleanly into a breaking wave; only a portion of the wave is able to stack up tall.
As our experiments demonstrated, it can be concluded that when people are engulfed within tsunami waves, PFDs will provide them with a higher chance of survival because they will remain on the surface of tsunami waves and are still able to breathe.
IF YOU ARE UNDER A TSUNAMI WARNING:
GROUND SHAKING, a LOUD OCEAN ROAR, or the WATER RECEDING UNUSUALLY FAR exposing the sea floor are all nature’s warnings that a tsunami may be coming. If you observe any of these warning signs, immediately walk to higher ground or inland.
The first megatsunami to be documented in detail in Indonesia remains one of the largest tsunamis on record.
Here is a report on other “minor” deadly tsunamis occurred in the last 10 years:
Should a tsunami occur and you cannot get to higher ground, stay inside where you are protected from the water. It’s best to be on the landward side of the house, away from windows. Often tsunamis occur in multiple waves that can occur minutes apart, but also as much as one hour apart.
In a total of 25 tidal waves classified as a tsunami since 142 a total of 5,010 people died in Greece. Compared to other countries, Tsunamis therefore occur more often than average, but still moderate. The strongest tidal wave registered in Greece so far reached a height of 30 meters.
In some places a tsunami may cause the sea to rise vertically only a few inches or feet. In other places tsunamis have been known to surge vertically as high as 100 feet (30 meters). Most tsunamis cause the sea to rise no more than 10 feet (3 meters).
Tsunamis have no names, at least not yet. Nor do earthquakes or floods. … The system of naming of Atlantic cyclones (known as hurricanes or typhoons), is a fairly old practice, but giving names to cyclones that originate in the northern Indian Ocean and affect South Asian countries began only at the turn of this century.
Yangtze River Floods, China.
In the period between July and August 1931, China suffered excessive rainfall which, in conjunction with the spring snowmelt in the mountains, led to floods along the Yangtze River which led to what is considered to be the deadliest natural disaster in world history.
The 10 most significant natural disasters worldwide by death toll from 1980 to 2019
Characteristic | Death toll |
---|---|
Earthquake, tsunami (Thailand*, December 26, 2004) | 220,000 |
Earthquake (Haiti, January 12, 2010) | 159,000 |
Cyclone Nargis, storm surge (Myanmar, May 2-5, 2008) | 140,000 |
– No such event – a mega tsunami – has occurred in either the Atlantic or Pacific oceans in recorded history. NONE. – The colossal collapses of Krakatau or Santorin (the two most similar known happenings) generated catastrophic waves in the immediate area but hazardous waves did not propagate to distant shores.
