The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks for the term that describes the point of origin of an earthquake. 2. **Identifying the Options**: The options provided are: - Seismic focus - Epicentre - Tectonic fault - Tectonic gap 3. **Analyzing Each Option**: - **Seismic focus**: This is the exact point inside the Earth's crust where the earthquake originates. It is also referred to as the hypocentre. - **Epicentre**: This is the point on the Earth's surface that is directly above the seismic focus. It is not the origin but rather the location on the surface above it. - **Tectonic fault**: This refers to fractures in the Earth's crust where movement has occurred. It is related to earthquakes but does not specifically denote the origin of an earthquake. - **Tectonic gap**: This term refers to areas where there has been little or no seismic activity, often found at divergent boundaries. It does not indicate the point of origin of an earthquake. 4. **Selecting the Correct Answer**: Based on the definitions, the correct answer is **seismic focus**, as it is the specific point where the earthquake begins. 5. **Conclusion**: Therefore, the point of origin of an earthquake is called the **seismic focus**. ---

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?
