Epicenter effects
The closer the focus of an earthquake is to the surface, the more damage to structures (buildings) it causes.
Measuring Earthquake methods
Mascalli scale being what we feel and richter scale 1 to 10.
What is Aftershock
Aftershock is an earthquake that occurs after a previous earthquake.
Where do earthquakes occur.
along plate boundaries.
What are the strongest version of earthquake.
The strongest earthquakes occur near convergent boundaries.
What are shallow earthquakes
Shallow earthquakes occur along divergent and transform-fault boundaries.
what are seismometers
Earthquakes are measing device which detect and plot earthquake vibrations.
