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
- 10.3 – 41.5km
- Mean velocity, P wave
- 4.9km/s
- Mean velocity, S wave
- 2.9km/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 6.1 km. P wave: 6 measurements, root-mean-square deviation 0.40 s. S wave: 4 measurements, root-mean-square deviation 0.28 s.
