A group velocity of seismic love surface wave and lithosphere structure in Antarctic Peninsula
This paper is based on the surface wave seismogram of South Sandwich Island earthquake (Ms = 6.4) recorded by Antarctic General Bernardo O'Higgins Station. We computed a group velocity dispersion of Love surface wave and obtained lithosphere structure by using the method of the matched-filter f...

This paper is based on the surface wave seismogram of South Sandwich Island earthquake (Ms = 6.4) recorded by Antarctic General Bernardo O'Higgins Station. We computed a group velocity dispersion of Love surface wave and obtained lithosphere structure by using the method of the matched-filter frequency-time analysis and grid dispersion inversion. Our result shows that crust structure below Antarctic Peninsula may be divided into three layers and their thickness are respectively 5km, 8km and 10km. Upper mantle velocity is 5.32 km/s and gradually changes into 5.11 - 4.9 km/s below 53 km. The minimum velocity is 4.8 km/s. It can be referred that Antarctic mantle is also of layered structure. |
