North Korea Nuclear Test - Recorded in Flagstaff

I've attached a couple of seismograms recording the North Korea nuclear test this past weekend. The top was recorded at the seismic station WUAZ, located just outside of Flagstaff, AZ. The bottom is a figure made by Andy Frassetto overlaying the 2016 and 2017 tests. Earthquake seismology plays an important role in understanding these tests and assessing the yield of the explosions. Further, these images demonstrate the sensitivity of seismic instruments in detecting these types of tests. The station in Flagstaff is ~6000 miles from North Korea. More information on the test and Andy's original figure are available here: ds.iris.edu/ds/nodes/dmc/specialevents/2017/09/03/2017-north-korean-nuclear-test/
