There is, however, a significant difference in their locations with respect to the coast, and, hence, with respect to the strongly coupled plate interface. The 15 June 1999 Tehuacán earthquake (H ∼60 km; Mw = 7.0) was located about 200 km inland from the coast (Singh et al., 1999) and in this sense was a typical intraplate event in the subducted slab. The Oaxaca earthquake of 30 September 1999 (H ∼45 km; Mw =... You do not have access to this content, please speak to your institutional administrator if you feel you should have access.
