Popis:	A unique atmospheric wave was recorded by a monostatic sound detection and ranging sodar system operating at Vapi, India 20.37° N, 72.90° E, on 25 January 2001 prior to the Bhuj, India, earthquake that jolted India on 26 January 2001. This precursory wave was the largest amplitude 480 m and lowest frequency wave 70.02 μHz ever recorded at 25 sodar operational sites in India/Maitri, Antarctica, in the past 30 years. It appears to be an Acoustic Gravity Wave AGW propagating in the lower atmosphere, and this precursory signature may support the hypothesis of AGW generation prior to a major earthquake.
