just a few additions to keysersoze's answer:
- "effective blast radius", i.e.
the distance from the explosion at which a submarine will suffer probably fatal damage for US airborne depth charges was as follows: ca. 14 m for 325 lb bombs (explosive charge: 100 kg of TNT) and 17 m for 650 lb bombs (211 kg of TNT). Source: TM 9-1980 Bombs for Aircraft, 1944.
- the effective radius of underwater explosions depends essentially on explosive charge's type and weight, on explosion's depth, and on the max shock pressure that structures exposed to the explosion can sustain. Some interesting articles on the subject:

Explosive charges of British and US depth charges (also reported by keysersoze) can be found on navweaps:

Please note that all the calculations and graphs reported in the first two links are referred to TNT. For other explosives, you should convert their weight into
TNT equivalents. Conversion factors for the most common WWII explosives can be found on Wikipedia and elsewhere on the web.
Sorry for the late reply
