// Phenomenon Tsunami
Tsunamis threaten the coasts and beaches all over the world. They occur in all oceans and seas, including the Mediterranean, the Atlantic, the Indian, the Pacific and in large lakes. About 10% of all tsunamis reach the beaches of the Mediterranean Sea.

Before the earthquake
The Indo-Australian plate is slowly pushing itself under the Eurasian plate with unimaginable force. The plates get caught and tensions build up in the rock.

// The formation of a tsunami
During the earthquake
The enormous tension at the edge of the Eurasian plate is becoming too great. The edge of the plate loosens and snaps back into its original position. The tensions, which have often built up over the years, are discharged in a sudden, jerky movement. These movements can then be felt as earthquakes.

After the earthquake
The sea floor has moved a few meters upwards. The water masses that are above the edge of the plate are displaced in a very short time. The resulting tsunami spreads in all directions in a circle.
We would like to equip you with the knowledge to recognize the early warning signs of a tsunami and understand how tsunamis develop. In this section of the web site we therefore make some information about the tsunami phenomenon available to you.
