Draw the location of the epicenter of an earthquake in Carmona, Silang,GMA Cavite if the hypothetical distance of epicenter in Carmona is 300 Km,Silang is 200km, and GMA is 200km

Respuesta :

The kinematics and geometry can locate the point where the earthquake occurs: Point of interception of the three circles

The earthquakes occur due to a sudden movement of two tectonic plates, this movement produces longitudinal and transverse waves with different speeds, called S and P waves. The speed of the waves is constant, so we can use the uniform kinematic movement relationship

           v = d / t

Where v is the speed of the wave, d is the distance and t is the time.

The speed of the two types of waves is known, they depend on the material and type of wave varies between 4 and 7 km / S, the time is measured in the seismometers, for which we can calculate the distance.

For a seismometer, the calculated distance corresponds to a circle, so to locate the epicenter of the earthquake we must have a minimum of three earthquakes, the point of intersection of the circles is the place of occurrence of the event, see the attachment for a diagram of the process.

In conclusion, with kinematics and geometry we can locate where the earthquake occurs: Point of interception of the three circles
