Earthquake Report: 5.3 in Guatamala, Lockloss on L1 & Then H1
-
EQ seen on USGS & Terramon after lockloss at 3:38utc (L1 also dropped a few minutes earlier), but NOTHING showed up on BLRMS until 3:48utc (very odd!) & didn't see huge signal on tidal striptool...so was hesitant to mark this as an EQ, but it finally showed up on BLRMS.

Magnitude: 5.3
-
Location: Guatamala
-
Starting time of event: Pretty much the H1 lockloss was when I noticed it and saw that it was already on USGS/Terramon
-
Lock status? L1 dropped out of lock followed by H1 a few minutes later.
This was a low magnitude but relatively close event which implies higher frequency ground motion. You can see a spike in the 0.3-1 Hz blrms at the lockloss time. I suspect that is what caused the lockloss.
