Realtime data from the OSU BPR/Tilt instrument at MARS
Examples of earthquake signals detected by the Nano-BPR sensor:
In the plots below, one hour of Nano-BPR data are shown in 10-minute segments on the x-axis with a variable scale in mm on the y-axis. Each 10-minute segment of the Nano-BPR data has been crudely "de-tided" by simply subtracting out the average linear trend for that time interval. The black arrows show the origin time of selected earthquakes and are followed within minutes by vertical ground motion at the MARS site, detected by the Nano-BPR. The earthquakes below are from Honshu Japan, southern California, the Mariana trench, Chile, Alaska and Ecuador and are all magnitude 5.4 - 9.0.
The Japan Honshu recording is different as it shows the tsunami signal arriving in addition to the actual earthquake.
