Tsunamis are severe oceanic storms that cause extreme devastation. They are a series of waves that can be miles long, up to 100 feet high, and can travel at 400 miles per hour. They are caused by significant and sudden disturbances of the sea’s surface. Volcanic eruptions, landslides, earthquakes can trigger a tsunami. A massive wall of water will wash ashore, and there is very little time or warning for those who live in the communities nearby. The series of waves can last for hours, and massive flooding adds to the problem. If you find yourself in a tsunami, get to high ground, keep calm, do not drive, and follow instructions from local officials.

The passage gives useful tips to keep people safe if they are caught in a tsunami. Which idea would help give residents more time to prepare before the storm arrives?

• Houses above sea-level

• Better flotation devices

• Early warning alert system

• Stronger roofs
