Krasheninnikov Volcano Latest News

The Nasa-ISRO Nisar satellite recently captured detailed radar views of Russia’s Krasheninnikov volcano as lava spread across Kamchatka.

About Krasheninnikov Volcano

• It is an active stratovolcano located in the Eastern Kamchatka Peninsula, Russia.
  • The Kamchatka Peninsula lies along the Pacific “Ring of Fire.”
  • There are 114 volcanoes on the Kamchatka Peninsula that have erupted during the Holocene Epoch (approximately 12,000 years ago to the present).
• The summit of the volcano reaches an elevation of 1,856 meters and lies within a collapse-originated caldera measuring 9 by 11 kilometers, dating back to 39,000 years ago. 
• The volcanic complex consists of two adjacent main stratovolcano cones. 
• The southern cone is crowned by a crater approximately 800 to 900 meters in diameter, while the northern cone is younger and exhibits a telescopic structure. 
• Within the northern cone, smaller craters measuring 800 meters in diameter and lava cones have formed. 
• The sides of both cones are covered with ejecta. 
• Volcanic Activity:
• Its last eruption took place about 400 or 600 years ago.
• 2025 Eruption: Krasheninnikov volcano erupted on 2 August 2025, three days after a nearby magnitude 8.8 earthquake. Ash emissions reached an altitude of 20,000 ft.

Key Facts about NISAR Mission

• NISAR (NASA-ISRO Synthetic Aperture Radar) is a joint Earth observation satellite mission between NASA and ISRO.
• It is a satellite equipped with advanced radar instruments for Earth observation.
• It was successfully launched on July 30, 2025, by ISRO’s GSLV-F16 rocket from the Satish Dhawan Space Centre in Sriharikota, India.  
• It marks the first-ever collaboration of its kind between India and the United States in radar-based Earth monitoring from space.
• NISAR maps the entire Earth’s surface every 12 days, enabling high-frequency, precise, and repeat observations.
• It is the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet’s surface less than a centimeter across.  
• NISAR will monitor earthquakes, volcanic activity, land deformation, and environmental changes, providing critical data for hazard assessment, disaster response, and resource management.
