A big quake from 1,389km away and 10km depth that took about three minutes to reach us and lasted at least six minutes (in the Mole Valley, at least). It was accompanied by many, many aftershocks and at least a couple of significant pre-shocks. Of these, only 4 quakes above M4.5 have been observable on our seismometer. The recording is bandpass filtered between 1 and 8 Hz.
