{{Main|Valley of Geysers}}

The Valley of Geysers ({{langx|ru|Долина гейзеров}}), located in the [[Kamchatka Peninsula]] of [[Russia]], is the second-largest concentration of geysers in the world. The area was discovered and explored by [[Tatyana Ustinova]] in 1941. There are about 200 geysers in the area, along with many hot-water springs and perpetual spouters. The area was formed by vigorous [[volcano|volcanic]] activity. The peculiar way of eruptions is an important feature of these geysers. Most of the geysers erupt at angles, and only very few have the geyser cones that exist at many other of the world's geyser fields.<ref name="uweb" /> On 3 June 2007, a massive [[mudflow]] influenced two-thirds of the valley.<ref name="NG">{{cite news |first=Aalok |last=Mehta |title=Photo in the News: Russia's Valley of the Geysers Lost in Landslide |url=http://news.nationalgeographic.com/news/2007/06/070605-geyser-valley.html |archive-url=https://web.archive.org/web/20070617203837/http://news.nationalgeographic.com/news/2007/06/070605-geyser-valley.html |url-status=dead |archive-date=17 June 2007 |work=[[National Geographic Society|National Geographic]] |date=16 April 2008 |access-date=7 June 2007}}</ref> It was then reported that a thermal lake was forming above the valley.<ref>{{cite news |first=Luke |last=Harding |title=Mudslide fully changes terrain in Kamchatka's Valley of Geysers |url=https://www.theguardian.com/russia/article/0,,2095579,00.html |work=[[The Guardian]] |date=5 June 2007 |access-date=16 April 2008}}</ref> Four of the eight thermal areas in the valley were covered by the landslide or by the lake.<ref>{{cite report|last=Leonov|first=AV|title=Katalog osnovnykh ob'ektov v Doline Geizerov (Kronotskii zapovednik, Kamchatka)|lang=ru|trans-title=A Catalog of Main Features in the Geyser Valley, Kronotskii Reserve, Kamchatka)|year=2012|url=http://www.kscnet.ru/ivs/lggp/cat/catalogue-2012.pdf }}</ref> [[Velikan Geyser]], one of the field's largest, was not buried in the slide: the slide shortened its period of eruption from 379 minutes before the slide to 339 minutes after (through 2010).<ref name=Kiryukhin>{{cite journal|last1=Kiryukhin|first1=AV|last2=Rychkova|first2=TV|last3=Dubinina|first3=EO|title=An analysis of hydrogeological behavior in the Geyser Valley, Kronotskii nature reserve, Kamchatka after the disaster of June 3, 2007|journal=J.
