2004 Indian Ocean earthquake and tsunami / Number of deaths

Waves as high as 30 feet (9 metres) struck the eastern coasts of India and Sri Lanka—some 750 miles (1,200 km) away—and traveled more than 1,800 miles (3,000 km) to East Africa. The final death toll was at least 225,000, mostly in Indonesia, Thailand, India, and Sri Lanka.

The tsunami from the 2004 M=9.1 Sumatra-Andaman earthquake was primarily caused by vertical displacement of the seafloor, in response to slip on the inter-plate thrust fault (see Tectonics section above).

However, the tsunami that followed killed more people than any other tsunami in recorded history, with 227,898 dead or missing in 14 countries across the Indian Ocean.

26, 2004, when a 9.1 magnitude earthquake off the Indonesian coast sent tidal wave speeding toward Indonesia, Thailand, Malaysia and Sri Lanka. It killed more than 230,000 people, including Wong. But Lang survived. She blacked out not long after the water hit, she said.

Notable people killed in the 2004 Asian tsunami: Jane Attenborough, 49, British arts administrator, daughter of actor Richard Attenborough. Troy Broadbridge, 24, Australian Football League player (Melbourne). Kristina Fröjmark, 47, Swedish reality TV star.

Deadliest Tsunami in History

On December 26, 2004, an extremely powerful earthquake occurred off the coast of the Indonesian island of Sumatra in the Indian Ocean.

Which part of the world is worst affected by tsunami? ›

Unlike the Pacific Ocean, which is wired for tsunami alerts by the United Nations Intergovernmental Oceanographic Commission, the Indian Ocean is largely devoid of comparable sensor technologies that detect earthquakes and issue tsunami warnings to affected countries.

One of the important programmes was the resettlement programme and infrastructure rehabilitation. During this period, seven tsunami escape buildings were also constructed. Four of the buildings were constructed in Banda Aceh, and one building was developed in each of West Aceh, Aceh Jaya, and Bireuen.

In Indonesia's Aceh province in Northern Sumatra, waves reached 167 feet (51 meters) and caused flooding up to three miles (five kilometers) inland. Animation of how the tsunami moved around the Indian Ocean.

Yet, the devastation caused by the 2004 tsunami (like most other tsunamis) could have been greatly reduced in many of the thirteen countries that were hit, particularly in those countries farther from the earthquake epicentre and subject to less massive tsunamis.

Unicef officials estimate that of the 30,000 people killed by the tsunamis in Sri Lanka, at least 10,000 were children. At the same time, Sri Lankan officials say the tsunamis created only about 200 orphans. Martin Dawes, a Unicef spokesman, said he believed that the number of children who had died would rise.

ANCHORAGE, Alaska (KTUU) - Alaska is home to the largest tsunami ever recorded. The 1,720-foot wave hit the tall banks of Lituya Bay in Southeast Alaska in 1958. There were two people who were in the bay who died, and four survived.

Excessive rainfall over central China in July and August of 1931 triggered the most deadly natural disaster in world history — the Central China floods of 1931. The Yangtze River overtopped its banks as spring snowmelt mingled with the over 24 inches (600 millimeters) of rain that fell during the month of July alone.

Tsunamis can occur any time of year, day or night. To escape a tsunami, go as high and as far as you can – ideally to a spot 100 feet above sea level or 2 miles away.

Comparing the Japan 2011 tsunami and the Tonga 2022 tsunami

By the time it got to California it was much smaller; however, it was still three times larger than what we experienced on January 15, 2022.

NUMBERS, NOT NAMES

However, 10 years after the one of the most devastating humanitarian disasters in recorded history, about 400 unclaimed bodies – 369 of them still unidentified – rest in metal coffins, marked with coded numbers.

A powerful lesson about survival — and more. On December 26, 2004, a tsunami in the Indian Ocean killed about 230,000 people, while virtually no animals died. They fled to higher ground before the water arrived.

Over 570,000 people were displaced and 179,000 buildings and homes destroyed in Indonesia as the wave swallowed large parts of the coastline. Massive reconstruction aid in Banda Aceh has since rebuilt a new city on top of the ruins.

Felipe Pomar, a big wave surfer from Peru, claims to have surfed a tsunami that struck the coast of Punta Hermosa, Peru, in 1974. He says the wave he rode during the tsunami did have a face, and he was able to turn on it.

Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees. Remarkably, only two fatalities occurred.

Waves from the devastating December 2004 tsunami were recorded along the Atlantic coast of North America, reports a new study published in Geophysical Research Letters.

Large tsunamis have occurred in the United States and will undoubtedly occur again. Significant earthquakes around the Pacific rim have generated tsunamis that struck Hawaii, Alaska, and the U.S. west coast.

The 1964 tsunami caused damage and loss of life across the Pacific. The Pacific Tsunami Warning Center indicates that the 1964 tsunami was the most disastrous tsunami to hit the U.S. West Coast.

Indonesia suffered the most deaths (167,540), followed by Sri Lanka (35,322), India (16,269), Thailand (8,212), Somalia (289), Maldives (108), Malaysia (75), Myanmar (61) and Tanzania (13).

Can a boat survive a tsunami? ›

Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor. But, do not risk your life and attempt to motor your boat into deep water if it is too close to wave arrival time.

If a vessel is hit by a tsunami near shore in shallow water, it will be shattered to pieces. Tsunamis can also be brutal to all sorts of life forms underwater. A diver, for instance, will hardly survive a tsunami because he will be caught by violent spinning currents.

Indonesia – 77 Tsunamis

The country has a total of 77 tsunamis on record. One of the most unforgettable ones was the tsunami triggered by the 2004 earthquake in Sumatra, Indonesia, on December 26. The tsunami was primarily responsible for the death of over 200,000 people, and property losses reached 10 billion dollars.

Hawaii: High to Very High

Hawaii has a long history of damaging tsunamis. Its tsunami record includes events caused by earthquakes both near and far.

On December 26 2004, waves triggered by a massive earthquake slammed into the coastlines of countries ringing the Indian Ocean. The death toll was enormous. Worldwide, it is estimated that about 230,000 people died that day.

There was no advanced tsunami warning system in the Indian Ocean. Nevertheless, PTWC staff did what they could to warn nations of the danger, including working with the U.S. State Department to alert nations in East Africa well in advance of the tsunami's arrival, possible saving thousands of lives.

When the Indian Ocean tsunami struck on Dec. 26, 2004, no one saw the massive waves coming. Authorities in Indonesia, where a 9.1 magnitude quake sparked the tsunami, weren't able to send out an alert because the country's sensor system had been hit by lightning.

Natural tsunami warnings include strong or long earthquakes, a loud roar (like a train or an airplane) from the ocean, and unusual ocean behavior. The ocean could look like a fast-rising flood or a wall of water. Or, it could drain away suddenly, showing the ocean floor, reefs and fish like a very low, low tide.

Within five years, individuals were back in homes they owned, often on their original land, in communities with new schools and in many cases improved infrastructure.

Who helped the people in the 2004 tsunami? ›

UNICEF was on the ground in the affected region at the time of the tsunami disaster and went to work immediately to provide lifesaving humanitarian relief to the survivors. Teams were mobilized in eight countries — Indonesia, Thailand, Myanmar, Malaysia, Sri Lanka, the Maldives, India and Somalia.

In wake of the disaster, Australia, India, Japan and the United States formed a coalition to coordinate aid efforts to streamline immediate assistance. However, at the Jakarta Summit on 6 January 2005, the coalition transferred responsibilities to the United Nations.

If no maps or signs are available, go to an area 100 feet above sea level or two miles inland, away from the coast. If you cannot get this far, go as high as possible. Every foot inland or upwards can make a difference. You may hear that a Tsunami Warning has been issued.

When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. However, tsunamis can surge up to 10 miles inland.

Drawback can be a warning that a tsunami is approaching the shoreline but the problem is that the time between the sea water receding and the full tsunami moving in is usually only seconds or, at best, a few minutes.

Why did so many people die on December 26, 2004? Dense coastal populations combined with a lack of tsunami-warning infrastructure came together to produce this horrific result.

Slow Water: Forests, ditches, slopes, or berms can slow down waves and filter out debris. The success of this method depends on correctly estimating the force of the tsunami. 3. Steering: Water can be steered to strategically placed angled walls, ditches and paved roads.

Measured in lives lost, this makes it one of the 10 worst earthquakes in recorded history, as well as the single worst tsunami in history. The worst affected countries were India, Indonesia, Malaysia, Maldives, Myanmar, Sri Lanka, Seychelles, Thailand and Somalia.

Hawaii: High to Very High

Hawaii has a long history of damaging tsunamis. Its tsunami record includes events caused by earthquakes both near and far. Significant tsunamis were produced locally in 1868 and 1975, but the majority of Hawaii's destructive tsunamis were produced by distant subduction zone earthquakes.

Tsunamigenic zones that threaten the Indian Coast have been identified, and they are the fault region off Sumatra, North Andaman, Car Nicobar in the Bay of Bengal and the Makran fault in the Arabian sea (Fig.

Which regions in India are prone to tsunami? ›

Answer: The government has compiled a list of tsunami-prone regions along India's eastern coast. Puri, Kakinada, Machilipatnam, Nizampatnam-Vetapalem, Chennai, Cuddalore-Pondicherry, Rameshwaram, Thoothukudi, Alappuzha-Chavara, Kochi are just a few of them.

The largest number of earthquakes occur around the rim of the Pacific Ocean associated with a series of volcanoes and deep-ocean trenches known as the "Ring of Fire". As a result, the largest source region for tsunamis is in the Pacific Ocean with 71% of all occurrences.

Large tsunamis have occurred in the United States and will undoubtedly occur again. Significant earthquakes around the Pacific rim have generated tsunamis that struck Hawaii, Alaska, and the U.S. west coast.

ANCHORAGE, Alaska (KTUU) - Alaska is home to the largest tsunami ever recorded. The 1,720-foot wave hit the tall banks of Lituya Bay in Southeast Alaska in 1958. There were two people who were in the bay who died, and four survived.

You should know that tsunamis aren't common in India due to several geographical factors that inhibit them. However, India isn't immune to tsunamis. Past records show the tsunami-affected areas in India that suffered a major blow. These tsunamis originated in the Indian Ocean.

The east and west coasts of India and the island regions are likely to be affected by Tsunamis generated mainly by subduction zone related earthquakes from the two potential source regions, viz., the Andaman-Nicobar-Sumatra Island Arc and the Makran subduction zone north of Arabian Sea.

The IS code assigns a zone factor of 0.10 for Zone 2. It is the zone with low chances of having earthquakes. Cities like Bangalore, Hyderabad, Coromandel coast and Tiruchirappalli are in this zone.

There is no season for tsunamis. A tsunami can happen any time, any season, and during any weather.

The time between waves ranges from five minutes to two hours. The first wave to reach the shore may not be the largest or the most damaging. It is not possible to predict how long a tsunami will last, how many waves there will be, or how much time there will be between waves.

What does a tsunami look like in real life? ›

They more likely resemble a very rapidly rising tide with the cycle occurring in just 5 to 60 minutes instead of 12 hours with potentially much greater height. Occasionally, tsunamis can form walls of water (known as tsunami bores) but tsunamis normally have the appearance of a fast-rising and fast-receding flood.
