A table for expedite location of deep earthquake foci
Main Article Content
Abstract
The expedite methods so far known for the location of deep earthquake foci and based on data from a single station can not be applied when the epicentral distance is short. In view of this consideration, a new method free from such limitation, and based on P, S and ScS phases and in tables prepared for such purpose, is proposed.
