Some false reports are circulating that Mt. Rainier is suddenly showing seismic tremor activity β€” this is not true. The signal being referenced is actually radio interference, most likely due to rime ice buildup on the antenna of one of our seismic stations.

I was on that giant GW170817 paper and think I personally may have been responsible for the change to have it only include the first three authors--I literally sent in a COA in 2019 with 5000 authors in it.
