When an earthquake first takes place, it is known as the main event. However, there may be a series of smaller earthquakes that could occur after the main one. These smaller earthquakes are known as the aftershocks and are capable of inflicting further damage. The aftershock is just as unpredictable as the main one. Showing the different Tectonic Plates How are earthquakes measured?
However, they are able to measure the magnitude of an earthquake or the amount of energy that is released from the earth when an earthquake takes place. Seismometers are used to record the seismic waves generated by an earthquake.
Seismologists are then able to use these recordings to determine where the earthquake was located and how strong it was. Seismic waves may also be used to map the interior of the earth. The Mercalli Intensity Scale is used to categorize the levels of shaking observed during an earthquake.

Building codes are guides used to ensuring that structures can withstand the effects of earthquakes and hurricanes. Building structures according to building codes would ensure the integrity of the structure. Not building structures on the correct type of foundation. Some soil types are more susceptible to ground movements than others. The soil type of the land upon which a structure is to be erected, would dictate the type of foundation the building should have; be it a shallow or deep foundation.
