Reaction of the geomagnetic field to the destruction of meteors in Yakutia (Vilyuysk) (on March 4, 2014 21:29 UT; 64.3°N, 123.1°E) and Khakassia (Sayanogorsk) (on December 6, 2016 11:37 UT; 52.9°N, 91.4°E) and the behavior of the geomagnetic field in the control days on March 7-8, 2014 and on December 4, 2016 according to the data of the magnetic observatory "Irkutsk" of the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Science (52.23°N, 104.25°E) were considered. The analysis of variations of the geomagnetic field components has shown that flights and explosions of the meteors were followed by emergence of geomagnetic disturbances near the magnetic observatory. Speeds of their propagation from places of the meteor explosions to the magnetic observatory were estimated. Possible mechanisms of influence of the explosions on the geomagnetic field are considered.
