At 00:42:03 UTC  Verbals announced an incoming 5.5M Earthquake from Tonga.
At 00:56:16:UTC H1 dropped from Observing due to a SQZr Unlock that was very likely caused by the increased ground motion.
We went back to Observing at 01:01:39 UTC after the SQZ Man relocked itself.
I did put the OPS mode into earthquake for that moment.
At 01:02:10 UTC Earthquake mode was activated.
