Overview

• Seismic stations have recorded more than 65 aftershocks since the July 30 magnitude 8.8 earthquake, including a 6.8 tremor on August 3 that shook the region.
• The Russian Emergency Ministry issued an orange aviation hazard code as ash plumes continue to rise above 6,000 meters and drift eastward over the Pacific.
• Officials confirm no populated areas or visitor sites lie in the ash cloud’s trajectory, minimizing immediate public risk.
• Researchers link the volcano’s sudden reactivation to energy injection into magmatic centers following the megathrust earthquake days earlier.
• Kamchatka’s location at the Pacific–North American plate boundary sustains around 30 active volcanoes, underscoring the region’s persistent geologic volatility.
