The Parascientific Pressure sensor located at our Fraser Delta site caught the oceanic signal of the local 6.3 earthquake of September 9, 2011 (12:41 PDT). The pressure sensor is located on a bottom mounted platform and samples at a rate of ~700 ms. The background trend is the rising tide, on which is superimposed the surface pressure signature of tsunami like waves “sloshing” about in the Strait of Georgia. The signal also shows up in other pressure sensors at this and our other Strait of Georgia locations, but because of the fast sample rate, this sensor shows enhanced variability.
