The latest Medford m4.1 had a lot of recordings. This is the latest one.
This reads 3 cm/s PGV with an Intensity of 4. I was quite impressed with all the instruments surrounding this earthquake. If they have a notion to do it, they can now determine directivity, and correlate Intensity with PGV. They won't though.
I would now like Mr. Mysterious to instrument buildings in Tulsa and OK City. We must show that all existing engineering assumptions are wrong. :)
