Infrasonic waves in the ionosphere generated by a weak earthquake
Original language description
A computer code has been developed to simulate the generation of infrasonic waves (frequencies considered <= 80 Hz) by a weak earthquake (magnitude similar to 3.6), their propagation through the atmosphere and their effects in the ionosphere. We provideestimates of the perturbations in the ionosphere at the height (similar to 160 km) where waves at the sounding frequency (3.59 MHz) of a continuous Doppler radar reflect. We have found that the pressure perturbation is 5.79 x 10(-7) Pa (0.26% of the ambient value), the temperature perturbation is 0.088 K (0.015% of the ambient value) and the electron density perturbation is 2 x 10(8) m(-3) (0.12% of the ambient value). The characteristic perturbation is found to be a bipolar pulse lasting similar to 25s, and the maximum Doppler shift is found to be similar to 0.08 Hz, which is too small to be detected by the Doppler radar at the time of the earthquake.
