Point of origin of earthquake is called

Which of the following statements relating to earthquakes is/are correct? 1.The point of origin of an earthquake is called the epicenter. 2.The lines joining the places which were affected by earthquake at the same point of time are called homoseismal lines. Select the correct answer using the code given below.

With reference to earthquakes, which of the following statements are correct? 1. Earthquakes largely occur along the converging plate boundaries. 2. Point of origin of earthquake in lithosphere is knonw as focus/hypocentre. 3. Intensity of earthquake decreases with distance from the epicentre. 4. Epicentre of earthquake always remains over continents only. Select the correct answer using the code given below.

The point on the surface of the earth vertically above the point of origin of the earthquake is

Earthquakes generate sound waves inside the earth. In case of the earth, both transverse (S) and longitudinal (P) waves can propagate. Typically, the speed of S waves is about 4.5 km s^-1 and that of P waves is 8.0 km s^(-1) . A seismograph records both P and S waves from an earthquake. this difference helps us to find the distanec of the point of origin of the earthquake. this point is called the epicenter. Q. if at the location of a seismograph the P waevs arrive 2 minute earlier, the distance of the epicenter from the location of the seismograph is

The reading of the time lag between the arrival of S and P waves gives us the distance of the epicenter from the location of a seismograph. the readings of what minimum number of seismographs would be necessary to pinpoint the location of an epicenter?

If only 2 seismograph readings are available, how may probable locations of an epicentre could be detected?
