0 depth is the surface of the earth,and increasing depth is downwards
what is the maximum depth of a deep-focus earthquake
There is no way to answer this. The magnitude of an earthquake does not correlate with its depth.
The distribution of earthquake with regard to the location and depth of focus can be best explained with tectonics.
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.
Earthquakes occurring at a depth of less than 70 km are classified as 'shallow-focus' earthquakes, while those with a focal-depth between 70 and 300 km are commonly termed 'mid-focus' or 'intermediate-depth' earthquake.

To convert measured depth to true vertical depth, first write down the measured depth. You will have to map an X, Y, Z point from that calculation, as well as using the azimuth and inclination.

The 2010 Chilean earthquake first hit just off the coast of Chile 325 km SW of Santiago at the depth of 59.4 km at 06:34 UTC. More accurately it occurred Latitude -35.83 and Longitude -72.67.
what is horizantal and vertical prototyping
Vertial Speed is final depth minus intitial depth divided by time
