The LAV-600 also features low observability by minimizing of infrared, acoustic and seismic signatures.

Twenty-one thousand tons makes a significant seismic signature.

The motion did not trigger an earthquake and was only detectable as silent, non-earthquake seismic signatures.

Moreover, the scientists found that its seismic signature matched those of known earthquakes in the region.

Recent research showed that these impacts against the opposite valley sides produced the seismic signatures interpreted as earthquakes.

Tornadoes also produce a detectable seismic signature, and research continues on isolating it and understanding the process.

The survivability is further enhanced from low observable technology to minimize levels of thermal, seismic and audio signatures, and minimal radar return.

The resulting data is used to locate the epicentre, and distinguish between the seismic signatures of an underground nuclear explosion and an earthquake.

In contrast, scientists say the distinctive seismic signature of the event clearly makes it natural in origin.

A travel time anomaly contains the seismic signature of buried inhomogeneities within the proximity of the ray path that connects two surface locations.
