Earthquakes happen when plates within the Earth suddenly shift or break under stress, sending shock waves rippling.
There are about 500,000 earthquakes every year worldwide.

Japan is the most seismically active country in the world
It is made up of 4 main islands and several thousand smaller islands which lie at the junction of three tectonic plates 10

22. Tsunamis
2004 Indian Ocean Tsunami- One of the most devastating natural disasters of modern times
Killed more than 225,000 people in 11 countries
Caused by an earthquake
Produced waves up to 100 feet high
Took anywhere from fifteen minutes to seven hours (for Somalia) to reach the various coastlines.
No longer works:

23. Warning Signs Tsunamis
On Maikhao beach in northern Thailand, a 10-year-old British tourist had studied tsunami in geography class at school and recognized the warning signs of the receding ocean and frothing bubbles. She and her parents warned others on the beach, which was evacuated safely.
This picture is of people who were curious when the waves retreated and they went to investigate.
The individuals have realized that it is a tsunami and are attempting to retreat, however, it is much too late for them.
Experts say that “a receding ocean may give people as much as five minutes’ warning to escape to high ground” (National Geographic)
