On 7/31, six small <= M3.0 quakes ocurred on the Mendocino NF near Rocky Basin Creek. All within hours of each other. The last cluster was 7/24-7/25. Total of 12 tremors so far. I don’t know of mapped nearby faults. Fascinating. Here’s the 7/31 M3.0 quake from my @raspishake. RaspberryShake RS 20210731 20210731 MNF Rocky Ridge Quakes
