Exotic Events

Exotic Seismic Events are things that are recorded on seismic instruments but are not earthquakes.  Natural events can include landslides, avalanches, floods, or meteors.  Man-made events include explosions, sonic-booms or football fans.  For a general review of such events see our exotic event blog page.

Below is a referenced list of such events recorded at the PNSN with either a blog entry or some write-up giving interesting details.  This list is ordered from most recent (top) to oldest. Those marked with the text, "TO BE ADDED" are known to have seismic records but no web report of them has yet been generated.
