What is a

A tsunami is characterized by waves
resulting from the displacement of a

typically occurring in oceans or
large lakes. This phenomenon can be
triggered by various events,
including earthquakes, volcanic
eruptions, and underwater explosions.

warnings via apps, SMS, or local systems. • Follow warinings:
• Educate & Prepare: Understand local stay updated with the help of official
risks, create an evacuation plan, and channels (News,TV and Radio)
practice drills. • Evacuate immediately:
• Set Communication Channels: Ensure Head to higher ground and avoid waiting
multiple ways of receiving info (radio, • stay connected:
apps, social media) and share family Inform family members and use social

10 fun facts about tsunamis:
1. Tsunami means "harbor wave" in Japanese, where "tsu" means harbor and
"nami" means wave.
2. Tsunamis are not just big waves but a series of waves that can last for hours,
with the first wave not always being the largest.
3.Tsunamis can travel across oceans at speeds up to 500-600 miles per hour
(800-970 km/h), as fast as a commercial jet.
4.Most tsunamis are caused by underwater earthquakes, but they can also be
triggered by volcanic eruptions, landslides, or even asteroid impacts.
5.The largest tsunami ever recorded was in 1958, caused by a landslide in Alaska,
and reached a height of 1,720 feet (524 meters).
6.Tsunamis in deep water are barely noticeable because their wave height is often just
a few feet, but they can grow massive when they reach shallow coastal areas.
7.Tsunamis can strike with little warning, though signs like a sudden retreat of the
ocean can sometimes give a clue that one is coming.
8The word "tidal wave" is a misnomer, as tsunamis are unrelated to tides and are
caused by seismic activity, not the moon’s gravitational pull.
9.Tsunamis can travel across entire oceans, and a tsunami generated in one part of the
world can reach distant coasts hours later.
10.Tsunamis can cause destruction far inland, as the waves can surge miles inland,
devastating coastal areas and ecosystems.

Tsunamis are very dangerous disasters but that does
not mean we cannot fight against it. If right measures
are taken than the they can be combated.
