Seen on multiple nodes managed by different institutions, feeding back to the CERI / Midwest USGS official charts across the region… what can only be described as low end vibrations, over a VERY large area.
NOT to be confused with earthquakes elsewhere around the planet, this is something I have not seen before over such a wide area.
Did the sensor network undergo some kind of damage? Is there some kind of interference happening? Is this a REAL detection of low frequency vibrations occurring?
Time will tell on this…
Here is the main link .. .click on CERI, SLU, or any of the other ‘nodes’.. then select 11/30/2012 (most current charts).. and then compare to a few days or weeks, or months ago by clicking back through the charts (listed by date):
use these links here to monitor earthquake activity nationally, and internationally:
