Overview

• On July 30, a magnitude 8.8 earthquake struck beneath the seabed off Russia’s Kamchatka Peninsula.
• Tsunami warnings were issued across the Pacific, including Mexico, before being downgraded or canceled once sea levels stabilized.
• Some Pacific coastlines saw only minor flooding with no reports of widespread inundation.
• Authorities and geoscientists are conducting ongoing evaluations of structural damage to assess the quake’s full impact on buildings and infrastructure.
• Experts warn that complex tsunami wave behavior complicates forecasting and point to gaps in global early-warning networks as a persistent vulnerability.
