I noticed there was a small Mag 4.0
earthquake 89km off the coast of
Ferndale, CA this morning. Here is the vertical component from PB.B046..EHZ., located in Petrolia, CA.
USGS looks to have this located on the Mendocino Fracture Zone, which is a common historical location, but I was surprised when looking at the
different seismographs, that the motion seemed to have the highest amplitude in the vertical direction. I thought it would have been much larger in
the E-W direction.
