Abstract:

Receiver function method, which is often used to obtain the information from the subsurface in the crust and mantle of the Earth, is a very useful geophysical prospecting tool. Data from one station KIP deployed in Hawaii area were processed by using the P-wave receiver function technique. We analyzed the characteristics of radial and tangential receiver functions, and committed the time-depth conversion for the radial receiver function to obtain the information from 410 km discontinuity. Results show that there is obvious laterally heterogeneity in southwest and northwest of station KIP, and the 410 km discontinuity becomes shallower with the depth of about 390 km which may be the response of a hot melt matter beneath the KIP station.

Key words: receiver function, laterally heterogeneous property, Oahu island, Hawaii area
