Lots of sporadic noise in the record. Some noise looks like earthquakes. Very long distances (>70 km) require an event window which extends at least 20 seconds beyond the event. Likely PmP joining Pg ~1330. PmP > is seen. Also first arrival becomes weak for a few km's before strengthening again at greater distance. Pn not visible with 2-16 filter Picks beyond 1410 are very weak but appear with lpf:6 Hz. |
