Location map
- Epicentre
- Station that recorded the event
Arrival times at the stations
Each station first records the P wave, the fastest, then the S wave. The farther a station is from the epicentre, the later the waves reach it and the wider the gap between the two.
- Stations
- 13
- Epicentral distance
- 4.5 – 119.1km
- Mean velocity, P wave
- 10.5km/s
- Mean velocity, S wave
- 4.6km/s
- P wave
- S wave
- Curve fitted to the measurements
Notes and method
Curves: travel time of a direct wave in a homogeneous medium. The velocity of each wave and an origin-time shift, common to both, are fitted to the measurements by least squares. Hypocenter at a depth of 11.4 km. P wave: 12 measurements, root-mean-square deviation 2.38 s. S wave: 13 measurements, root-mean-square deviation 4.41 s.
