Krasheninnikov is a caldera-type volcano located in Russia, positioned at coordinates 54.596° N, 160.27° E with an elevation of 1,816 meters. Operating within a subduction zone and continental crust tectonic setting exceeding 25 km in thickness, the volcano has a documented history featuring 32 confirmed eruptions cataloged in the Smithsonian Global Volcanism Program records.
According to the official structured record, the earliest recorded eruption began around 8050 BCE, utilizing uncalibrated radiocarbon isotopic evidence. The historical record spans millennia across various centuries before and after the common era, involving activity areas such as the southern cone, southern outer flank fissures, and northern outer flank fissures.
Eruption History and Magnitude
The confirmed eruptions at Krasheninnikov vary in scale and explosivity. Among the recorded events, the largest known Volcanic Explosivity Index (VEI) reaches 4.0. For instance, a confirmed eruption on the northern cone with a start date around 150 BCE was recorded with a VEI of 4.0, determined via calibrated radiocarbon isotopic evidence.
Other notable examples from the representative records include an eruption on the northern outer flank fissure starting around 5250 BCE and an earlier event on the southern cone and southern outer flank fissure starting around 8050 BCE. More recently, an eruption began on August 2, 2025, and concluded on March 25, 2026, with a recorded VEI of 3.0 based on reported observations.
Summary of Activity Scope
The Smithsonian Global Volcanism Program profile for Krasheninnikov reports a total of 32 confirmed eruptions. The timeline of these events covers a broad temporal distribution from the earliest recorded year of 8050 BCE through the latest recorded eruption period ending in March 2026. Out of the total confirmed eruptions, 9 episodes contain recorded Volcanic Explosivity Index (VEI) observations.
