DYNAMICS OF ERUPTIONS OF GROT GEYSER (VALLEY OF GEYSERS, KAMCHATKA) IN 2024

The paper presents the results of visual and instrumental observations of eruptions of the Grot geyser carried out in 2024 in the Valley of Geysers (Kamchatka). It was found that the eruption regime of Grot Geyser has changed significantly: Grot Geyser has turned from an irregularly erupting geyser into a relatively regular geyser with an interval between eruptions of 10.4 hours in the winter low season, a break during the most intense flood, and subsequent resumption of geyser activity with an interval of 24 hours. The eruption volume of Grot geyser is estimated at ≈70 m using the chloride-tracer method.
