Implication

Seismological analysis reveals shorter Pn travel times from a surface explosion across European recording stations, suggesting potential increases in near-distance wave velocity.

Key Points

To evaluate seismic wave travel times and velocities generated by the Burton-on-Trent surface explosion against standard travel-time tables.
Analyzed seismic wave arrival times recorded across four British and six continental European seismological stations.
Compared observed Pn and Sg wave arrivals to standard 1940 travel tables and prior observations from the Oppau explosion.
Pn travel times at approximately 8° distance for a surface focus were 3.9 ± 1.3 seconds shorter than predictions from the 1940 tables.
Upper-layer thickness reductions could not explain the travel-time anomaly, pointing instead to a potential increase in Pn wave velocity at short distances.
Sg waves were satisfactorily recorded, indicating that low velocities recorded during the Oppau explosion reflected ordinary measurement errors rather than wave misidentification.
