Low-pass philtre
Earth science; Seismology
Philtres a signal to remove frequencies above a given frequency, passes only the low frequencies.
High-pass philtre
Earth science; Seismology
Philtres a signal to remove frequencies below a given frequency, passes only the high frequencies.
Band-pass philtre
Earth science; Seismology
Philtres signal to retain only those frequencies within the required range, e.g. 5-40 Hz.
Tectonic earthquakes
Earth science; Seismology
Earthquakes resulting from sudden release of energy stored by major deformation of the Earth.
