Love wave
en.wikipedia.org...
~
Description:
The particle motion of a Love wave forms a horizontal line perpendicular to the direction of propagation (i.e. are transverse waves). Moving deeper into the material, motion can decrease to a "node" and then alternately increase and decrease as one examines deeper layers of particles.
Each year the southern California area has about 10,000 earthquakes. Most of them are so small that they are not felt. Only several hundred are greater than magnitude 3.0, and only about 15-20 are greater than magnitude 4.0. If there is a large earthquake, however, the aftershock sequence will produce many more earthquakes of all magnitudes for many months.

CWC STS2 mass positions offset at 6.8V, re-centered.
This station is flagged with additional issues in seinetwatch.
Red warning for clock quality (can see below that its stuck at Q=1)
I'll see if I can restart the clock. If it was yellow we could let it go, but not in this case.
Also a red flag for sequence errors.
Thanks.
Alberto

Yes Ellen,
The STS2 at this site mass positions are offset by 6.8V. above this sensor's range of 5V.
This station yellow warning was superceded by a red warning of clock quality in the SeisnetWatch,
therefore I did not see it in this morning's round of mass re-centering.
So your user is 100% right.
I'll proceed to re-center this STS-2 sensor immediately, and send a notification.
Thanks,
Alberto
