TXESP continues researching the answer, if any, to the question “How well can the Raspberry Shake seismograph **detect earthquakes** and provide high quality data comparable to other educational and research-quality seismographs?”
Example: a magnitude M3.1 Earthquake occurred near Monahans, Texas on September 6, 2019 at 15:55 hrs UTC. Two of three Raspberry Shake seismographs recorded ground motion at 2.2 pol deg away (Station R70B6), 2.4 polar deg away (Station R376A) and 6.6 pol deg away (Station RAD87). Note that each seismogram has a 1.0 Hz LP filter applied.
Compare how well each seismograph detected (or not detected) this small event.
