Concetti Chiave
- An earthquake is the movement of the Earth's surface, originating from a focus point inside the Earth.
- The epicentre is the surface point directly above the earthquake's focus.
- Earthquakes can cause significant damage to infrastructure and contribute to land pollution.
- Underwater earthquakes can lead to tsunamis, which are giant tidal waves.
- The effects of earthquakes are measured using the Richter scale and the Mercalli scale.
Earthquake
Earthquake is the movement of the earth's surface. It occur on two points: the point inside the Earth where an earthquake begins is called the focus. The point on the surface directly above the focus is called the epicentre.
Earthquakes can cause damage to buildings, bridges, and roads. Earthquakes, in fact, are a natural disasters and a cause of land pollution.
When an earthquake occurs in the sea, it can cause a tsunami. it is a giant tidal wave or series of waves.
The effects of the earthquakes are based on two scale: the Richter scale and the Mercalli scale.
The Richter scale is based on a mathematical study by Richter Charles. He was a pioneer in seismological research.
