What is an epicenter?

To find the scientists an epicenter, they need readingof at least three seismographs in the region. They use data from each seismograph to determine how far it was from an epicenter when an earthquake occurred, and this data is used to find a place on the ground above the hypocentre. Computer programs are available today, although historically it can be done with a compass and map, drawing circles around the location of each seismograph and searching for a point where the circles intersect.

When the earthquake information is published, the data usually includes an epicenter. The earthquake maps, regularly updated in geologically active regions, show all earthquakes WHICHs have appeared in the period set and points to the location of each epicenter for the comfort of people who consult maps. Patterns on the map of the earthquake can also reveal trends that may be important, such as increased activity along a particular error.

Knowledge of Epicentre's location can also be important for trying to help disasters because they say to people where they should concentrate withvou energy. It can also be valuable when trying to predict the tsunami and shocks that may be followed by earthquakes and threats to workers and citizens.
