NSF is also reporting that it took out one of the lightning rod towers. It'll be interesting to see how much damage the pad and ground equipment sustained.

It was very likely the largest explosion in Florida spaceflight history. Considerably larger than when SpaceX blew up AMOS-6 in 2016, and that required a full rebuild of the pad infrastructure over 18 months.

I'm wondering about how it compares to AMOS-6. New glen is bigger than Falcon 9 & uses fully cryogenic propellant, so there would be definitively more energy involved.

On the other hand a lot of the damage on the Falcon pad was IIRC due to burning kerosene getting everywhere on the pad & melting everything.

In this case I would expect all the liquid oxygen and methane to either be involved in the explosion or quickly vaporize, possibly resulting in a different damage pattern on the pad.

I don’t believe they were using cryogenic propellant in the first stage yet. They were preparing for it just before this.
