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).
What tectonic plates caused the 2004 tsunami?
On 26 December 2004 a tsunami occurred in the Indian Ocean. It was the result of the Indio-Australian Plate subducting below the Eurasian Plate. It was caused by an earthquake measuring more than magnitude 9.
Which of these was caused by the earthquake that struck in the Indian Ocean in 2004?
the Indian Ocean tsunami of 2004
This quake caused the Indian Ocean tsunami of 2004, which reached out across the Indian Ocean, devastating coastal areas with waves that in some places reached a height of 30 feet (9 metres) or more when they hit the shoreline.

A series of massive tsunami waves grew up to 30 m (100 ft) high once heading inland, after being created by the underwater seismic activity offshore.
Did anyone survive the 2004 tsunami?
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.

What are the 3 major causes of tsunamis?
What are the causes of tsunamis?
- Earthquakes. It can be generated by movements along fault zones associated with plate boundaries.
- Landslides. A landslide that occurs along the coast can force large amounts of water into the sea, disturbing the water and generate a tsunami.
- Volcanic Eruption.
- Extraterrestrial Collision.
Why was there no warning for the 2004 tsunami?
A spokesman for the disaster agency said the warning was canceled after the waves made land. Unconfirmed reports also claimed that sirens did not sound in some areas because they were left without power due to the initial earthquake and did not have a secondary source of energy.
Can dogs sense tsunami?
Humans can’t hear infrasound—the lowest key on a piano is about the lowest tone the human ear can detect. But many animals—dogs, elephants, giraffes, hippos, tigers, pigeons, even cassowaries—can hear infrasound waves.
Can birds sense a tsunami?
Scientists believe it is the birds’ ability to hear infrasound — low-frequency sounds inaudible to humans — that allows the birds to sense storms and tsunamis coming.
What was the cause of tsunami?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Has the US ever had a tsunami?
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.
What’s the tallest tsunami ever recorded?
1,720 foot
In fact, the largest tsunami wave ever recorded broke on a cool July night in 1958 and only claimed five lives. A 1,720 foot tsunami towered over Lituya Bay, a quiet fjord in Alaska, after an earthquake rumbled 13 miles away.
Who is responsible for tsunami?
Most tsunamis are caused by earthquakes on converging tectonic plate boundaries. According to the Global Historical Tsunami Database, since 1900, over 80% of likely tsunamis were generated by earthquakes.
What’s the biggest tsunami ever?
1958 Lituya Bay earthquake and megatsunamiTsunami / Biggest
Lituya Bay, Alaska, July 9, 1958
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.
What’s the worst tsunami ever?

Elephants. Scientists have long known about elephants’ response to death. When a living elephant comes in contact with a dead elephant, it usually falls silent and often spends several minutes investigating the body with its trunk and feet.
What happens to ocean animals during a tsunami?
Some marine animals probably won’t even notice that anything out of the ordinary happened. Others will be killed quickly and painlessly by the force of the tsunami. Still others will die later as a result of habitat destruction or water-quality issues caused by the tsunami’s passage.
What happens to animals during tsunami?
How do tsunamis affect the life of fish and marine animals? Tsunami currents increase strongly in shallow water where weaker corals can be broken by the force of the tsunami. Fish and marine animals are sometimes stranded on the land after they are carried by the currents to shore.
Why so few animals were killed in the tsunami?
Very few animals were killed in the tsunami. Perhaps they feel the tremor much before humans do. Secondly, the animals have sixth sense. Some experts also believe that animals have an acute sense of hearing that helps them to hear or feel the earth’s vibration.
