Abstract
The geophysical effects of a fire in Moscow on December 09, 2022, which, along with open combustion, was accompanied by an explosion of containers with combustible materials, are analyzed. The results of instrumental observations have shown that during the maximum combustion period, not only acoustic signals, but also variations in the electric field intensity are clearly recorded at a distance of ~ 25 km. At the same distances, the fire caused changes in the wind rose. During the maximum development of the fire, geomagnetic disturbances were recorded at a distance of ~ 90 km from the fire source, which is explained by the effect of internal gravitational waves on the ionosphere, resulting from the formation of a powerful vertical flow of heated material.
