Method and apparatus for seismic tornado detection |
摘要 |
A tornado warning system having means for monitoring seismic waves of a predetermined frequency range including long-period seismic waves and short-period seismic waves. The seismic waves are associated with and produced in the ground as a result of an approaching tornado. The warning system comprises means for detecting the seismic waves including the long-period seismic waves and the short-period seismic waves and for providing an electrical output indicative thereof. Circuit means are provided for processing the electrical output to provide an output signal indicative of the long-period seismic waves and the short-period seismic waves. Alarm means are provided for receiving the output signal from the circuit means to generate an alarm to warn of the presence of a tornado.
