List of tsunamis

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, but are a worldwide natural phenomenon. They are possible wherever large bodies of water are found, including inland lakes, where they can be caused by landslides and glacier calving. Very small tsunamis, non-destructive and undetectable without specialized equipment, occur frequently as a result of minor earthquakes and other events. Around 1600 BC, the eruption of Thira devastated Aegean sites including Akrotiri (prehistoric city). Some Minoan sites in eastern Crete may have been damaged by ensuing tsunamis. The oldest recorded tsunami occurred in 479 BC. It destroyed a Persian army that was attacking the town of Potidaea in Greece. As early as 426 BC, the Greek historian Thucydides inquired in his book History of the Peloponnesian War (3.89.1–6) about the causes of tsunamis. He argued that such events could only be explained as a consequence of ocean earthquakes, and could see no other possible causes.

Impact event
Description
An astronomical object between 37 and 58 kilometres (23 and 36 mi) wide traveling at 20 kilometres per second (12 mi/s) struck the Earth east of what is now Johannesburg, South Africa, near South Africa's border with Eswatini, in what was then an Archean ocean that covered most of the planet, creating a crater about 500 kilometres (300 mi) wide. The impact generated a megatsunami that probably extended to a depth of thousands of metres beneath the surface of the ocean and rose to the height of a skyscraper when it reached shorelines.

Description
An asteroid 10 kilometres (6 mi) in diameter struck the Earth, generating a megatsunami with an initial wave height of 1,500 metres (5,000 ft) which struck coastlines in the Gulf of Mexico with waves 100 metres (300 ft) tall and reached heights of up to 14 metres (46 ft) in the North Atlantic and South Pacific. The impact also triggered giant landslides and slumps which produced additional megatsunamis of various sizes in the region, and seismic waves from it caused seiches of 10 to 100 metres (30 to 300 ft) in height in an inland sea at Tanis, 3,000 kilometres (2,000 mi) away.

This tsunami also devastated many large cities in what is now Libya and Tunisia. The anniversary of the disaster was still commemorated annually in the late sixth century in Alexandria as a "day of horror." Researchers at the University of Cambridge recently carbon dated corals off the coast of Crete that were raised 10 metres (30 ft) and out of the water during the earthquake, indicating that the tsunami was generated by an earthquake on a pronounced fault in the Hellenic Trench. Scientists estimate that such an uplift is likely to only occur once every 5,000 years; however, the other segments of the fault could slip on a similar scale every 800 years or so.

Description
Tens of thousands of Portuguese people who survived the Great Lisbon earthquake on 1 November 1755 were killed by a tsunami 40 minutes later. Many fled to the coast, an area safe from fires and debris during aftershocks. These people watched the sea recede, revealing a seabed littered with lost cargo and shipwrecks. The tsunami then struck with a maximum height of 15 metres (49 ft), traveling inland. The earthquake, tsunami, and fires killed 40,000 to 50,000 people. Historical records of early navigators such as Vasco da Gama were lost, and among the destroyed buildings were most of Portugal's examples of Manueline architecture. Eighteenth-century Europeans struggled to understand the disaster within religious and rational belief systems, and Enlightenment philosophers, notably Voltaire, wrote about the event. The philosophical concept of the sublime, as described by Immanuel Kant was inspired by attempts to understand the enormity of the Lisbon earthquake and tsunami. The tsunami took just over 4 hours to travel over 1,000 miles (1,600 km) to Cornwall in the United Kingdom. An account by Arnold Boscowitz claimed "great loss of life." It also struck Galway, Ireland, and caused heavy damage to the Spanish Arch section of the city wall.

Tsunamis were the main cause of death in the worst volcanic disaster in Japanese history, an eruption of Mount Unzen, Hizen Province (Nagasaki Prefecture), Kyushu, Japan. Towards the end of 1791, a series of earthquakes on the western flank of Mount Unzen moved towards Fugen-dake, one of the peaks of Mount Unzen. In February 1792, Fugen-dake erupted, starting two months of lava flows. The earthquakes continued, approaching the city of Shimabara. On the night of 21 May 1792, two major earthquakes preceded the collapse of the eastern flank of Mount Unzen's Mayuyama dome. An avalanche swept across Shimabara and Ariake Bay, causing a tsunami. The tsunami hit Higo Province (Kumamoto Prefecture) along Ariake Bay before recovering. Of the estimated 15,000 deaths, around 5,000 are believed to have died from the landslide, around 5,000 from the tsunami in Higo Province, and around 5,000 from the tsunami that returned to Shimabara. The waves reached a height of 100 m (300 ft), making it a small megatsunami.

1700 Cascadia earthquake
Earthquake
On 26 January 1700, the Cascadia earthquake, with an estimated magnitude of 9.0, ruptured the Cascadia subduction zone (C SZ) from Vancouver Island to California, and triggered a massive tsunami recorded in Japan and by the oral traditions of indigenous peoples of the Pacific Northwest. The wave caught the Japanese off guard, not knowing its origin, and was explained in the book, The Orphan Tsunami.

1703 Genroku earthquake
Earthquake
On 31 December 1703, an 8.2 magnitude earthquake struck Edo. A tsunami up to 11.7 metres (38 ft) high was recorded along the coast of the Kantō Region. Official reports put the death toll of the earthquake disaster at 5,233 people, but some estimates put it as high as 200,000.

1707 Hōei earthquake
Earthquake
On 28 October 1707, during the Hōei era, an 8.4 magnitude earthquake and tsunami up to 10 metres (30 ft) high hit Tosa Province (Kōchi Prefecture). More than 29,000 houses were destroyed, causing around 30,000 deaths. In Tosa, 11,170 houses were razed to the ground, and 18,441 people drowned. Some 700 drowned and 603 houses were razed to the ground in Osaka. The hot springs of Yunomine, Kii (Tanabe, Wakayama), Sanji, Ryujin, Kii (Tanabe, Wakayama) Kanayana (Shirahama, Wakayama) and Dōgo, Iyo (Matsuyama, Ehime) stopped flowing.

1737 Kamchatka earthquake
Earthquake
On 17 October 1737, a 9.0-9.3 MW earthquake in the Pacific Ocean off the southeastern coast of the Kamchatka Peninsula generated a tsunami. The tsunami reached a height of 30 metres (100 ft) in Avacha Bay, and elsewhere on the peninsula's coast waves of 6.3 metres (21 ft) and 63 metres (207 ft) were reported and evidence of a run-up height of 70 metres (200 ft) was found on one ridge. In the northern Kuril Islands, the wave was 20 metres (70 ft) tall, while on Amchitka in the Aleutian Islands it reached 12 to 16 metres (39 to 52 ft).

1755
Lisbon, Portugal
1755 Lisbon earthquake
Earthquake
Tens of thousands of Portuguese people who survived the Great Lisbon earthquake on 1 November 1755 were killed by a tsunami 40 minutes later. Many fled to the coast, an area safe from fires and debris during aftershocks. These people watched the sea recede, revealing a seabed littered with lost cargo and shipwrecks. The tsunami then struck with a maximum height of 15 metres (49 ft), traveling inland. The earthquake, tsunami, and fires killed 40,000 to 50,000 people. Historical records of early navigators such as Vasco da Gama were lost, and among the destroyed buildings were most of Portugal's examples of Manueline architecture. Eighteenth-century Europeans struggled to understand the disaster within religious and rational belief systems, and Enlightenment philosophers, notably Voltaire, wrote about the event. The philosophical concept of the sublime, as described by Immanuel Kant was inspired by attempts to understand the enormity of the Lisbon earthquake and tsunami. The tsunami took just over 4 hours to travel over 1,000 miles (1,600 km) to Cornwall in the United Kingdom. An account by Arnold Boscowitz claimed "great loss of life." It also struck Galway, Ireland, and caused heavy damage to the Spanish Arch section of the city wall.

Lisbon, Portugal
1761 Lisbon earthquake
Earthquake
More than five years after the 1755 earthquake, on 31 March 1761, another event with an estimated magnitude of 8.5 shook the Iberian Peninsula. It generated a tsunami up to 2.4 metres (7.9 ft) at Lisbon. In Cornwall, the tsunami reached more than 1 metre (3 ft) in height. The details of this earthquake are largely unknown, censored by the Portuguese government to prevent panic.

1771 Great Yaeyama Tsunami
Earthquake
An underwater earthquake with an estimated magnitude of 7.4 occurred near the Yaeyama Islands in the former Ryūkyū Kingdom (present day Okinawa, Japan) on 24 April 1771 at about 08:00. The earthquake is not believed to have directly caused any deaths, but the resulting tsunami killed an estimated 12,000 people. Advance estimates at Ishigaki Island range from 30 to 85.4 metres (100 to 280 ft). The tsunami was followed by malaria epidemics and crop failures. It took 148 years for the population to return to pre-tsunami levels.
1781
Pingtung, Taiwan
In April or May 1781, according to Taiwan County records, in Jiadong, Pingtung, a 3-metre (10 ft) wave hit the city. Fish and shrimp rampaged wildly on the shore and nearby fishing villages were wiped out. However, no earthquake was reported. A different source claims that a 30-metre (100 ft) wave also hit Tainan. One possibility is a misrecording of the date, corresponding to the Great Yaeyama event mentioned above.
1783
Calabria, Italy
1783 Calabrian earthquakes
Earthquake
The earthquake was the second of a sequence of five shocks that shook Calabria between 5 February and 28 March 1783. The citizens of Scilla spent the night after the first earthquake on the beach, where they were washed away by the tsunami, causing 1,500 deaths. The tsunami was caused by the collapse of Monte Paci into the sea, near the city. Estimated deaths from earthquake and tsunami are 32,000 to 50,000.
1792
Kyūshū, Japan
1792 Unzen earthquake and tsunami
Volcanic processes
Tsunamis were the main cause of death in the worst volcanic disaster in Japanese history, an eruption of Mount Unzen, Hizen Province (Nagasaki Prefecture), Kyushu, Japan. Towards the end of 1791, a series of earthquakes on the western flank of Mount Unzen moved towards Fugen-dake, one of the peaks of Mount Unzen. In February 1792, Fugen-dake erupted, starting two months of lava flows. The earthquakes continued, approaching the city of Shimabara. On the night of 21 May 1792, two major earthquakes preceded the collapse of the eastern flank of Mount Unzen's Mayuyama dome. An avalanche swept across Shimabara and Ariake Bay, causing a tsunami. The tsunami hit Higo Province (Kumamoto Prefecture) along Ariake Bay before recovering. Of the estimated 15,000 deaths, around 5,000 are believed to have died from the landslide, around 5,000 from the tsunami in Higo Province, and around 5,000 from the tsunami that returned to Shimabara. The waves reached a height of 100 m (300 ft), making it a small megatsunami.
1793

Volcanic eruption
The volcano on the island of Krakatoa in the Dutch East-Indies (present-day Indonesia) exploded on 27 August 1883, partially emptying its subterranean magma chamber, causing much of the land and seabed to collapse onto it. The collapse generated a series of large tsunami waves, some more than 40 metres (130 ft) above sea level. Tsunami waves were observed throughout the Indian Ocean, the Pacific Ocean, and as far away as the west coast of the United States and South America. On the opposing coasts of Java and Sumatra flooding from the sea reached many miles inland and caused such loss of life that one area was never resettled, reverting to jungle and is now the Ujung Kulon Nature Reserve.

Residents of these islands were completely caught off guard by the onset of the tsunami due to the inability to broadcast any warnings from the destroyed poles at the Scotch Cap Light on Unimak Island in Alaska. The tsunami is known as the Hawaii April Fools' Day Tsunami because it happened on 1 April and many people thought it was an April Fool's Day prank. The result was the creation of a tsunami warning system known as the Pacific Tsunami Warning Center (PTWC), established in 1949 for the countries of Oceania.

The wave reached Kauai, Hawaii, 4+1⁄2 hours after the quake, and Hilo, Hawaii, almost 5 hours later. Residents of these islands were completely caught off guard by the onset of the tsunami due to the inability to broadcast any warnings from the destroyed poles at the Scotch Cap Light on Unimak Island in Alaska. The tsunami is known as the Hawaii April Fools' Day Tsunami because it happened on 1 April and many people thought it was an April Fool's Day prank. The result was the creation of a tsunami warning system known as the Pacific Tsunami Warning Center (PTWC), established in 1949 for the countries of Oceania.

Earthquake
The Nankai earthquake of 21 December 1946 had a magnitude of 8.4 and occurred at 04:19 (local time) to the southwestern Japan in the Nankai Trough. This event was one of the Nankai megathrust earthquakes, periodic earthquakes observed off the southern coast of the Kii Peninsula and Shikoku, Japan, every 100 to 150 years. The subsequent tsunami leveled 1451 houses and caused 1500 deaths in Japan, and was observed on tide gauges in California, Hawaii, and Peru. The coastal cities of Kushimoto and Kainan on the Kii Peninsula were particularly hard hit. The earthquake caused more than 1400 deaths, with the tsunami being the main cause.

The impact in the waters of Gilbert Inlet generated a local tsunami that crashed against the southwest coast and swept the spur separating Gilbert Inlet from the main Lituya Bay. The wave continued through Lituya Bay, over La Chaussee Spit and into the Gulf of Alaska. The force of the wave removed all trees and vegetation from a height of 1,720 feet (520 m) above sea level. This is the highest wave ever recorded. The scale of this wave was much larger than ordinary tsunamis, eventually leading to the new category of megatsunamis.

At 262 metres (860 ft), it was one of the tallest dams in the world. On 9 October 1963 a landslide of some 260,000,000 cubic metres (340,000,000 cu yd) of forest, dirt, and rock fell into the reservoir at speeds of up to 110 km/h (68 mph). The resulting water displacement caused 50,000,000 cubic metres (65,000,000 cu yd) of water to overflow the dam in a megatsunami wave 250 metres (820 ft) high. The resulting flood destroyed the villages of Longarone, Pirago, Rivalta, Villanova, and Faè, killing 1,450 people. Almost 2,000 people perished in total.

However, on Okushiri, a small island near the epicenter, some waves reaching 30 metres (98 ft) hit two to five minutes after the earthquake. Despite being surrounded by tsunami barriers, Aonae, a town on a low-lying peninsula, was hit over the next hour by 13 waves over two metres (6 ft 7 in) high that came from multiple directions, including waves that bounced off Hokkaido. Of the 250 people killed as a result of the earthquake, 197 were victims of the tsunami that hit Okushiri; the waves also caused deaths in Hokkaido. While many residents, recalling the May 1983 tsunami (see above), survived by evacuating on foot, many others underestimated how soon the waves would arrive (the 1983 tsunami took 17 minutes to hit Okushiri) and died trying to evacuate by car.

Valdivia, Chile, and Pacific Ocean
1960 Valdivia earthquake or Great Chilean earthquake
Earthquake
The magnitude 9.5 earthquake of 22 May 1960, the largest earthquake ever recorded, generated one of the most destructive tsunamis of the 20th century. The tsunami spread across the Pacific Ocean, with waves measuring up to 25 metres (82 ft) high in places. The first tsunami wave hit Hilo, Hawaii, approximately 15 hours after its origin. The highest wave at Hilo Bay was measured at around 10.7 m (35 ft). 61 people died, allegedly due to people not heeding the warning sirens. Nearly 22 hours after the earthquake, waves up to 3 metres (10 ft) above high tide hit the coast of Sanriku in Japan, killing 142 people. Up to 6,000 people died in total worldwide from the earthquake and tsunami.

The Vajont Dam as seen from Longarone on 25 September 2012, showing the top 60 to 70 metres (197 to 230 ft). The 200–250-metre (656–820-foot) megatsunami would have obscured virtually all of the sky in this picture. The Vajont Dam was completed in 1961 under Monte Toc, 100 km (62 mi) north of Venice, Italy. At 262 metres (860 ft), it was one of the tallest dams in the world. On 9 October 1963 a landslide of some 260,000,000 cubic metres (340,000,000 cu yd) of forest, dirt, and rock fell into the reservoir at speeds of up to 110 km/h (68 mph). The resulting water displacement caused 50,000,000 cubic metres (65,000,000 cu yd) of water to overflow the dam in a megatsunami wave 250 metres (820 ft) high. The resulting flood destroyed the villages of Longarone, Pirago, Rivalta, Villanova, and Faè, killing 1,450 people. Almost 2,000 people perished in total.

On 21 November 2000, a 90,000,000-cubic-metre (120,000,000 cu yd) landslide with a mass of 260,000,000 tons fell from an elevation of 1,000 to 1,400 metres (3,300 to 4,600 ft) at Paatuut on the Nuussuaq Peninsula on the west coast of Greenland, reaching a speed of 140 kilometres per hour (87 mph). About 30,000,000 cubic metres (39,000,000 cu yd) of material with a mass of 87,000,000 tons entered Sullorsuaq Strait (known in Danish as Vaigat Strait), generating a megatsunami. The wave had a run-up height of 50 metres (160 ft) near the landslide and 28 metres (92 ft) at Qullissat, the site of an abandoned settlement across the strait on Disko Island, 20 kilometres (11 nmi; 12 mi) away, where it inundated the coast as far as 100 metres (300 ft) inland. Refracted energy from the tsunami created a wave with a run-up height of 3 metres (10 ft) that destroyed boats at the closest populated village, Saqqaq, on the southwestern coast of the Nuussuaq Peninsula 40 kilometres (25 mi) from the landslide.

Animation showing the tsunami radiation from the 1,600 km (1,000 mi) rupture The 2004 Indian Ocean earthquake (moment magnitude 9.1–9.3) triggered a series of tsunamis on 26 December 2004 that devastated coastlines surrounding the Indian Ocean, killing an estimated 227,898 people (167,540 in Indonesia alone), making it the deadliest tsunami and one of the deadliest natural disasters in recorded history. The earthquake was the second largest earthquake in recorded history. The initial surge was measured at a height of approximately 33 meters (108 ft), making it one of the largest earthquake-generated tsunamis in recorded history. The tsunami killed people from the immediate vicinity of the earthquake in Indonesia, Thailand, and the northwest coast of Malaysia, to thousands of miles away in Bangladesh, India, Sri Lanka, the Maldives, and as far afield as Somalia, Kenya, and Tanzania. This tsunami that crossed the Indian Ocean is an example of a teletsunami, which travels great distances across the open ocean, and an ocean-wide tsunami. It became known as the "Boxing Day Tsunami" because it hit on Boxing Day (26 December). Unlike the Pacific Ocean, there was no organized warning service covering the Indian Ocean. This was due in part to the absence of major tsunamis since August 1883 (the Krakatoa eruption, see above). In light of the 2004 Indian Ocean tsunami, UNESCO and other world bodies called for an international tsunami monitoring system.

Starting at 350 metres (1,150 ft) above water height, it caused a tsunami 20 to 30 metres (70 to 100 ft) high through the caldera and potentially larger at localized impact points. Thanks to the late hour, there were no tourists present; however, search and rescue personnel noted a cloud of steam rising from the volcano, apparently geothermal steam released by the landslide. It is not known if geothermal activity played a role in the landslide. The landslide involved a total of 30 to 50 million cubic metres (39 to 65 million cubic yards) of material, which raised the water level in the caldera by 1 to 2 metres (3 to 7 ft).

On 30 July 2025, a magnitude 8.8 earthquake struck off the eastern coast of the Kamchatka Peninsula and triggered tsunami warnings across the Pacific.. Waves with estimated heights of 15 to 19 metres (49 to 62 ft) struck unpopulated sections of the Kamchatka coastline, though in populated areas waves were limited to 5 to 6 metres (16 to 20 ft).

Tracy Arm, Alaska, United States
2025 Tracy Arm landslide and tsunami
Landslide
On 10 August 2025, a landslide with a volume of at least 100,000,000 cubic metres (130,000,000 cubic yards) occurred near the terminus of South Sawyer Glacier in Tracy Arm, a fjord in Southeast Alaska. Some or most of the landslide entered the waters of Tracy Arm, triggering a tsunami with a run-up on the opposite shore of 470 to 500 metres (1,542 to 1,640 ft) and of at least 30 metres (98 ft) on nearby Sawyer Island. The tsunami damaged tents and kayaks at a camping site on Harbour Island at the mouth of Tracy Arm, where tsunami waves reached an estimated height of 3.0 to 4.6 metres (10 to 15 ft) and water rose to at least 7.6 metres (25 ft) above the high tide line. A gauge at Juneau, Alaska, 80 miles (129 km) from the landslide, recorded tsunami waves with a maximum height of 36 centimetres (14 in).
