Study Warns of Potential Mega-Tsunami Threatening US Coast
Imagine a giant wall of water, much bigger than any wave you've seen, rushing towards the coast.
Scientists are worried about this happening because of earthquakes in the ocean.
They've studied a specific area in the Pacific Northwest, and found it could cause a huge wave, called a mega-tsunami, if a big earthquake hits.
This wave could be hundreds of feet tall and travel far inland, potentially wiping out cities.
The scientists warn there's a chance this could happen, so it's important to be prepared.
This kind of disaster would be sudden, giving little time to react, so it's very dangerous.
A study highlights the threat of a mega-tsunami potentially hitting the US coastline.
The Cascadia Subduction Zone is identified as a high-risk area for a triggering earthquake.
Researchers warn of a 15% chance of a magnitude 8.0 earthquake in the next 50 years.
The worst-hit areas could include cities in Washington, Oregon, and California.
Mega-tsunamis can reach hundreds or even thousands of feet high and travel miles inland.
