6.2 Geometry of the observation
The Indian Ocean tsunami-induced TIPs were analyzed using the TIPs
obtained at 870 thousand IPPs formed by all the GPS stations covering
the Indian ocean from 40o E to 130oE and 50o S to 50o N (Fig. 3).
Similarly, Nepal earthquake near-field CIP analysis was carried out at
950 thousand IPPs over the Himalayan region from 80o E
to 92o E and 25o N to
31o N (Fig. 4).
