arrival time-travel time
Seismologists determine an earthquake's starting time by analyzing data from multiple seismic stations that record the seismic waves generated by the earthquake. By comparing the arrival times of these waves at different stations, seismologists can triangulate the earthquake's epicenter and calculate the origin time. This information is crucial for understanding the earthquake's characteristics and for issuing timely warnings and alerts.
The origin of an earthquake is called the hypocenter or focus. This is the point underground where the earthquake rupture begins.
The point of origin of an Earthquake within the earth is known as the hypocentre. It can also be called the focus.Directly above this on the surface is the earthquake's epicenter.
The point on the earth's surface closest to the origin of an earthquake is called the epicenter. This is where the seismic waves generated by the earthquake first reach the surface.

The Great East Japan Earthquake, also known as the 2011 Tohoku earthquake, occurred at 2:46 PM JST on March 11, 2011. The earthquake triggered a powerful tsunami that struck the east coast of Japan shortly after.
Focus
The point of origin of an earthquake is called the hypocentre or focus. The epicenter is the point on the surface directly above the focus.
To find the lagtime of an earthquake, subtract the origin time of the earthquake from the arrival time of the seismic waves at a specific location. This lagtime represents the delay between the earthquake occurrence and the arrival of seismic waves at that location. The lagtime is a crucial parameter for determining the distance of the earthquake epicenter from the recording station.
The origin of an earthquake is called the hypocenter or focus. This is the point within the Earth where the earthquake begins and energy is released.
