  After an explosive eruption of the Hunga Tonga volcano on January 15, 2022,
disturbances were observed at a distance of about 12000km in Northern Tien Shan
among the variations of the atmosphere pressure, of telluric current, and of
the Doppler frequency shift of ionospheric signal. At 16:00:55UTC a pulse of
atmospheric pressure was detected there with a peak amplitude of 1.3hPa and
propagation speed of 0.3056km/s, equal to the velocity of Lamb wave. In the
variations of the Doppler frequency shift, the disturbances of two types were
registered on the 3212km and 2969km long inclined radio-paths, one of which
arose as a response to the passage of a Lamb wave (0.3059km/s) through the
reflection point of radio wave, and another as reaction to the acoustic-gravity
wave (0.2602km/s). Two successive perturbations were also detected in the
records of telluric current at the arrival times of the Lamb and
acoustic-gravity waves into the registration point. According to the parameters
of the Lamb wave, an energy transfer into the atmosphere at the explosion of
the Hunga Tonga volcano was roughly estimated as 2000Mt of TNT equivalent.
