• A magnitude-6.8 aftershock struck off the Kuril Islands early Sunday, underscoring the region’s ongoing seismic unrest.
• This activity follows days after nearby Klyuchevskoy’s eruption and the July 30 magnitude-8.8 quake that triggered tsunami warnings across the Pacific.
• Tsunami waves inundated Severo-Kurilsk’s port, submerging a fishing plant but causing no reported casualties.
• No populated areas have recorded ashfall, and emergency teams remain on standby along Kamchatka’s coastline.
