Figure 2 - Velocity Recorded at PAS

Figure 2. a) North-south component of velocity recorded at PAS. AS1 occurred 62s after the mainshock and is distinct from mainshock coda at high frequencies. The relative amplitudes of both events indicates that AS1 is Mw6.0. b) North-south component of velocity recorded at PAS for AS2 (January 17, 1994 23:33 UTC) approximately 11 hours after the mainshock. Moment tensor analysis revealed that this event was Mw6.0.
