The depth of an earthquake, or hypocenter, is typically determined using data from seismic waves recorded by seismographs. When an earthquake occurs, it generates primary (P) and secondary (S) waves that travel through the Earth at different speeds. By analyzing the time difference between the arrival of these waves at multiple seismic stations, scientists can triangulate the location and depth of the earthquake's origin. This method, known as triangulation or seismic wave analysis, provides a precise estimate of the hypocenter's depth.

What is also known as the 'focus' - the place underground where an earthquake originates?

The point underground where an earthquake originates is known as the hypocenter or the focus. This is the specific location within the Earth's crust where the seismic energy is released, leading to the generation of seismic waves that cause the earthquake.


Where is Point in earth where earthquakes start?

Within the Earth, the focal point of the energy released in an earthquake is called the hypocentre or focus. This is where an earthquake actually begins. The place on the Earth's surface directly above this point is known as the epicentre.


What is the origin of an earthquake under the surface of earth called?

This is known as the focus or hypocentre of an earthquake.


Where was the epicentre and hypocentre of the earthquake in Haiti on January 12 2010?

The earthquake's epicentre (the point on the surface directly above the earthquake rupture zone) was 25 km WSW of the Haitian capital city, Port-Au-Prince. According to the US Geological Survey the exact co-ordinates were 18.457°N, 72.533°W. The hypocentre (the point within the Earth where the rupture actually occurred) was located at a depth of 13 km below the surface. Please see the related links and question.


How deep was the focus of the Haiti earthquake?

Assuming that you are referring to the earthquake that occured in January 2010, the focus or hypocentre (the point within the Earth where the rupture actually occurred) was located at a depth of 13 km below the surface. Please see the related question for further information.

What is the depth of focus of an earthquake whose magnitude is 7.2 below sea level?

The depth of focus of an earthquake with a magnitude of 7.2 can range from 10 to 700 kilometers below the surface of the Earth. At this depth, the earthquake originates within the crust or upper mantle, releasing energy that can cause significant shaking and damage near the surface.
