This teleseism is a M 6.3 which occurred near the coast of Guerrero,Mexico approximately 3000 km southeast of MOBB. The velocity data has been 0.03-0.12 Hz BP filtered to enhance the earthquake signal. Note that all three components recorded the event but the N-component has a higher background noise level than do the other two components.
