The focal depth of an earthquake is how far beneath the earth's surface the hypo-center of the earthquake.Because of its location in the Indian ocean, however, its focal depth is measured as 30 kilometers below mean sea level, rather than being measured at the seabed.
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.
The tsunami of December 26, 2004 occured in the Indian Ocean and impacted several nations including Indonesia, Thailand, Sri Lanka, India, The Maldives, and Somalia, killing over 230,000 people.
The zero on the vertical axis for earthquake depth vs latitude graph indicates that there is no earthquake occurring at the Earth's surface (0 km depth) at the extreme latitude ends (poles). This is due to the way earthquakes are recorded by seismometers, typically located on the Earth's surface. As earthquakes cannot happen at the exact poles, the graph reflects this by showing a zero depth at the top of the vertical axis.
No, the depth of focus of an earthquake does not directly determine its intensity. The intensity of an earthquake is primarily influenced by the earthquake's magnitude and the distance between the epicenter and populated areas. The depth of focus mainly affects the distribution of seismic waves and can influence the shaking intensity experienced at the surface.

The depth of Lake Toba is 505m (1,666 feet). It is also 100 kilometres long and 30 kilometres wide and located in the middle of the northern par of Sumatra.
i think it was this earthquake..Valdivia, Chile1960 Valdivia earthquake it had 6,000 causalities and was 33km in depth
The hypocentre (the point within the Earth where the rupture actually occurred) of the January 2010 earthquake was located at a depth of 13 km below the surface.
