The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Klyuchevskoy volcano (also spelled Kliuchevsky, Klyuchevskaya) is Kamchatka's highest and one of the world's most active volcanoes.
Klyuchevskoy is located in a remote area of the Kamchatka peninsula. It has a large active crater with frequent strombolian and lava fountain eruptions.
Klyuchevskoy volcano (Kamchatka): new strombolian-type eruption

Ash emission from Klyuchevskoy volcano last evening (KVERT webcam)
The activity of the volcano has again increased into a new eruptive phase. KVERT raised the Aviation Color Code to orange.
After more than a month of relative calm, with only degassing and sporadic weak ash emissions, the volcano began a more sustained phase of strombolian activity shortly after midnight (local time) between yesterday and today (1-2 March). So far, this activity has been accompanied by mild to moderate ash emissions, but no lava flow (as typical for most eruptions at the volcano). This could change quickly if the effusion rate increases.
The most recent eruptive phase from Klyuchevskoy took place between April-November last year and was characterized by both lava flows and mild to moderate explosive activity at the summit, at fluctuating intensity. It was followed by a period with sporadic weak ash emissions followed during December and January, showing that the activity at the volcano never really stopped completely.
Kliuchevskoi is Kamchatka's highest and most active volcano. Since its origin about 6000 years ago, the beautifully symmetrical, 4835-m-high basaltic stratovolcano has produced frequent moderate-volume explosive and effusive eruptions without major periods of inactivity. Kliuchevskoi rises above a saddle NE of sharp-peaked Kamen volcano and lies SE of the broad Ushkovsky massif. More than 100 flank eruptions have occurred at Kliuchevskoi during the past roughly 3000 years, with most lateral craters and cones occurring along radial fissures between the unconfined NE-to-SE flanks of the conical volcano between 500 m and 3600 m elevation. The morphology of its 700-m-wide summit crater has been frequently modified by historical eruptions, which have been recorded since the late-17th century. Historical eruptions have originated primarily from the summit crater, but have also included numerous major explosive and effusive eruptions from flank craters.
Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
