Incoming! Then Outgoing! Waves Generated by Russian Meteor Recorded Crossing the U.S.
Network of stations with seismometers and air pressure sensors detected the blast waves
The National Science Foundation said:
The National Science Foundation- (NSF) supported stations are used to study earthquakes and the Earth's deep interior.
While thousands of earthquakes around the globe are recorded by seismometers in these stations--part of the permanent Global Seismographic Network (GSN) and EarthScope's temporary Transportable Array (TA)--signals from large meteor impacts are far less common.
The meteor explosion near Chelyabinsk on Feb. 15, 2013, generated ground motions and air pressure waves in the atmosphere. The stations picked up the signals with seismometers and air pressure sensors
