7.3 Earthquake from the Aleutians
- 20:43:00 UTC I saw the OTR station on picket-fence start seeing some motion
- 20:43:08 UTC Verbal warned of an incoming nearby earthquake from Canada
- 20:43:10 UTC Earthquake mode activated
- 20:43:25 UTC I opened up ISI_CONFIG and saw it was a 7.3 and decided click the big red "VERY LARGE EQ" button for the first time
- This ended up tripping the ISI on HAM7 & 8 and the OPO in HAM7.
- 20:45 - 48 UTC The S wave peaked and tripped HAM1 ISI and BS ISI ST1 & 2
- The R wave came through a few minutes later
