Comparing Technology, Part 4: the BIG(er) guy won from Bolivia

WATCH the Earth move LIVE

Station E1TX has two seismographs – an EQ-1 Educational Vertical Seismograph (sold by Ward’s) – and a less expensive, “plug-and-play” Raspberry Shake. While it may be assumed that the RS is not as technologically advance as the EQ-1, we have observed in the Magnitude 6.8 earthquake detected low (teleseismic) frequencies more often with greater amplitudes than it’s counterpart (the EQ-1).  This very deep event, >560kms, occurred on 04/02/2018 at 13:40hrs UTC.

Below: Shown is a screenshot comparing the EQ-1 seismogram with an extracted seismogram from the Raspberry Shake.  Very intriguing!  To note, the epicentral distance is 59.5 pol deg and the focal depth is 564kms.
