Another large earthquake recorded on our seismometer overnight, this time from Southern Qinghai in China, with a magnitude of 6.9. In common with the a few earthquakes we have recorded recently, because one of the nodal planes of the source (which I’m guessing to be the fault plane at the minute) is directed towards us here at Keele, the P-wave is nodal so we don’t see it well (it should arrive at about 40 seconds past midnight on the 14th here). We do, however, see the S-wave and the Love and Rayleigh wave trains quite well.
More details from the USGS here.
Recorded as part of the UK School Seismology Project.
