This graph is based on the earthquake log for RaspberryShake 4D RD29A located in Chino Hills, Ca. I have only started to log keep a detailed log 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. New quakes will be posted as soon as possible. (Full log here). Whats is the Core Shadow Zone? |
