Name the difference between epicenter and hypocenter

You can name the difference between a epi- and a hypocentre.

Earthquakes start in the Earth’s crust. The deepest point is called the hypocentre. The point on the Earth’s surface right above the hypocentre is called the epicentre. That is where you feel the worst tremors.

C4.2: The Great East Japan Disaster

On Friday 11 March 2011, the north-east of Japan was hit by a heavy earthquake. The quake caused a tsunami that claimed many victims and caused a lot of damage.

How do a tsunami occur?

It starts with a seaquake

Earth plates slide past each other. Because this is difficult, the tension between the plates is built up. If there is too much tension, the plates will shoot to discharge the tension.

You can name how the Richter scale works.

"Scale for measuring the force of an earthquake."
