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.

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. Depth not determined: hypocenter placed at the surface for the calculation. P wave: 5 measurements, root-mean-square deviation 0.14 s. S wave: 4 measurements, root-mean-square deviation 0.23 s.
