The Hunga Tonga – Hunga Ha’apai volcano erupted on January 15, 2022, and produced the strongest atmospheric blast ever recorded on modern instruments. It also generated a tsunami that affected the entire Pacific Ocean, and was recorded in parts of the Atlantic Ocean and Mediterranean Sea.

What caused the Tonga tsunami in 2022?
A volcanic eruption in Tonga on 15 January 2022 surprised scientists by triggering two types of tsunamis: “classic” tsunamis caused by the displacement of large volumes of water, and meteotsunamis caused by fast-moving pressure disturbances in the atmosphere.

Can tsunami reach 100 feet?
When they strike land, most tsunamis are less than 10 feet high, but in extreme cases, they can exceed 100 feet near their source. A tsunami may come onshore like a fast-rising flood or a wall of turbulent water, and a large tsunami can flood low-lying coastal areas more than a mile inland.
How do you survive a tsunami?
Tsunamis
- If caused by an earthquake, Drop, Cover, then Hold On to protect yourself from the earthquake first.
- Get to high ground as far inland as possible.

- Listen to emergency information and alerts.
- Evacuate: DO NOT wait!
Can you swim in a tsunami?
If caught by a tsunami wave, it is better not to swim, but rather to grab a floating object and allow the current to carry you. Tsunamis retain their energy, meaning they can travel across entire oceans with limited energy loss.

Is Yellowstone going to erupt?
Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.
What is the biggest tsunami on record?
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.
How many tsunamis happen a year?
twice per
According to the Global Historical Tsunami Database, tsunamis that cause damage or deaths near their source occur approximately twice per year. Tsunamis that cause damage or deaths on distant shores (more than 1,000 kilometers, 620 miles, away) occur about twice per decade. 1.6 Where do tsunamis happen?

What are 3 signs a tsunami is coming?
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.
Can you survive a tsunami in a plane?
Tsunamis, on land, can reach over 100 feet tall. They’re a giant flood that can move miles inland and can wash buildings away. A plane would start bobbing in the water like a cork (because of their design) before crashing into a building and crumpling like a piece of paper. Anyone on board will die.
