Description
Geyser Vladimir is located at the lower part of high, steep and loose slope and very close to geyser Andrey and has V-shaped eruption jet. It was discovered in 2016 by Alexander and Marina Belousov to the right of geyser Andrey (named after A.V. Leonov, the author of the Kronotsky Nature Reserve Geyser Catalog) and proposed to name the new geyser Vladimir in honor of Vladimir Leonidovich Leonov (1950–2016), an employee of the Institute of Volcanology, who made a great contribution to the study of the geology of Kamchatka, including Valley of Geysers, and father of A.V. Leonov (Belousovs, 2017, 2020).  During observations of these closely located geysers, it turned out that their channels are connected to each other. Vladimir's eruption always begins at the end of Andrey's eruption, and after the end of Vladimir's eruption, Andrey's activity pauses for about 30 minutes, after which it resumes as usual, then before the next Vladimir eruption, 4-6 Andrey eruptions occur, and at the end of Andrey's last eruption, bubbling begins in Vladimir's griffin, turning into fountaining.  Vladimir's activity in 2016-2017 was unstable with the fountaining period 1-5,5 hours. Later, Vladimir became a stable geyser with period of 30-60 min and duration of eruptions 1-1.5 min. On May 3, 2023, a small snow-mud avalanche came down from the slope above onto these geysers. On May 4, both geysers were covered with a snow-mud mass, streams from above flowed into the geysers, the water in their channels was muddy, the geysers did not erupt. On May 5, Andrey was already working in the usual mode. On the evening of May 5, Vladimir erupted for the first time in 3 days, itthis eruption was 30 seconds longer than usual. On May 6, Vladimir was already working in the usual mode (Belousovs, report 2023). In 2024, its period was 20-40 min.
