The phenomena of hydrothermal explosions are known enough in world practice of development of geothermal deposits. By the example of hydrothermal explosion near a borehole reinjection Mutnovskaya GeoES the mechanism of the process and his morphological attributes is considered. Value of application of the data of kinetic temperature of the thermal channels sensor ASTER received at processing for the spatial and time analysis of hydrothermal explosions is marked. Considered explosion is multievent which is response of the hydrothermal reservoir to superfluous pressure.
