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
- 6
- Epicentral distance
- 8.1 – 41.3km
- Mean velocity, P wave
- 6.6km/s
- Mean velocity, S wave
- 3.1km/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 8.3 km. P wave: 6 measurements, root-mean-square deviation 0.90 s. S wave: 5 measurements, root-mean-square deviation 0.39 s.
