RaspberryShake-4D RD29A Earthquake Log Summary

Live Stream from RasbperryShake 4D Seismograph
(RD29A) in Chino Hills


This is a summary of the earthquakes that have been detected by RaspberryShake-4D RD29A located in Chino Hills, Ca. (Full log here). Rows with bold lettering triggered the alarm on the live stream.

If the Ratio (Current signal level/Average signal level for the past 20 seconds) is more than 4 for more than 1.5 seconds, the alarm is triggered. The larger the Ratio, the larger the seismic signal that first arrived at the seismograph.

Rows in non-bold italics did not trigger the alarm, but were recorded by the RaspberryShake. I have only started to log non-alarm quakes since 7/21/20. So, the log before this date is incomplete (My RaspberryShake 4D came online in October 2017).

Additions to the logs are not automated. So, new quakes will be posted as soon as possible.
