Explain the 'how' and 'when' of tsunamis by discussing how tsunamis are created and that unfortunately tsunamis can occur at any time. Then explain the 'who' and 'where' of tsunamis by defining what hydrologists and oceanographers do and where tsunamis occur, namely most often in the Ring of Fire. Discuss what to do if you find yourself in a tsunami by discussing what to do before, during, and after a tsunami. First, find out if you are in a high-risk area and sign up for local alerts if you are. You should also know the difference between a tsunami warning and a tsunami watch. During a tsunami, you might feel an earthquake and should drop, cover, and hold. Ask students why you might feel an earthquake. Discuss the signs of a tsunami. After a tsunami, you should be aware of aftershocks, listen to local authorities, and only return home when it is safe to do so. Also, check everything carefully as the water could have damaged or broken many things. Have students fill in the blanks with words from the word bank. Then ask students to draw a line to match the preparation to something you should do before, during, or after a tsunami. Finally, ask them to spin the wheel and give an action they should do before, during, or after a tsunami.
