Using Seismographs in Florida, South Carolina to Detect Hurricane Dorian

Can #hurricanes be detected by #seismographs? Let’s watch three seismographs across Florida and South Carolina as #HurricaneDorian gets closer to the US Southeast Coast.  Because seismograph stations are impacted by internet outages, local weather conditions, re-calibration and mechanical failures, #TXESP is observing three seismographs simultaneously.  They are located in #Nokomis, FL (#IRIS Station #BCFL), Disney’s Wilderness Preservation near #Orlando (#IU Station DWPF) FL, and in New Hope, SC (#US Station #NHSC).  We can begin to see the effect of Dorian’s approach on the recorded seismograms ….note the increase in “noise” on the 2nd seismogram images at each location.  This is actually detecting the increase in ground motion (called microseisms).  This amplified motion is created by the ocean waves from the hurricane which beat on the ocean shore.
