QUICK SUMMARY:
H1 has been unlocked for 6 hours due to a large earthquake and an elevated uSeism.
Initial attempts to lock are failing at locking ALS.
The microSeism isn't as high as it was yesterday so perhaps we can get H1 locked today, But the Primary microSeism looks higher than it was yesteday.
