Mutnovsky (Russia): Recorded Eruptions and Historical Activity

Overview of Mutnovsky Volcano

Mutnovsky is a complex volcano located in Russia at coordinates 52.449 latitude and 158.196 longitude. It reaches an elevation of 2,288 meters and sits in a subduction zone setting on continental crust thicker than 25 kilometers. According to records maintained by the Smithsonian Global Volcanism Program, Mutnovsky has 45 confirmed volcanic eruptions spanning from 7550 BCE through 2000 CE.

Historical Activity and Evidence Methods

The eruption history of Mutnovsky is documented through both pre-historical geological methods and modern observational tracking. Ancient eruptions, including events dated to 7550 BCE, 4550 BCE, and 750 CE, were identified through tephrochronological correlation. Recorded activity increased in frequency during recent centuries, with 5 confirmed eruptions in the 19th century CE and 13 confirmed eruptions in the 20th century CE. A reported observation documented an eruption beginning on July 5, 1917, while hydrophonic observations recorded the volcano's latest confirmed event on June 30, 2000.

Explosivity and Event Scale

Explosive strength across Mutnovsky's documented history is classified using the Volcanic Explosivity Index (VEI). Among all 45 confirmed eruptions, the maximum recorded magnitude reached VEI 3.0. Eruptions reaching VEI 3.0 include the event in 750 CE and the July 5, 1917 event. Smaller explosive events have also occurred, such as the June 30, 2000 eruption, which recorded a VEI of 1.0.
