A measure of the degree to which an earthquake is felt by the people and the amount of damage caused.
what is intensity?
These are the three types of seismic waves.
What are s-waves, p-waves and surface waves?
This is the area underground where the seismic waves of an earthquake originate.
a crack in the earths surface where tectonic plates slide.

Scale measuring the intensity, effects, and observations of an earthquake. The scale goes from 1 to 10
what is the Mercalli Scale?
a mountain that produces magma, lava, and ash and is formed by cracks in the Earth's surface. these can occur in any place where there is a deep crack.
