The distribution of earthquake with regard to the location and depth of focus can be best explained with tectonics.
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 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.
0 depth is the surface of the earth,and increasing depth is downwards
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.

The location for the magnitude 9.0 earthquake in Japan on March 11, 2011 was 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, Tōhoku, near Sendai at a depth of 32 kilometers (20 miles).

i think it was this earthquake..Valdivia, Chile1960 Valdivia earthquake it had 6,000 causalities and was 33km in depth
