• Tonga, with low-lying terrain, evacuated as a precaution; no casualties occurred.
• Similarities noted with the 1952 Kamchatka earthquake (magnitude 9.0, 18-meter tsunami).
• Japan’s Kuji Port recorded the highest tsunami wave at 1 meter, mirroring 1952 data.

Summary
A magnitude 8.7 earthquake struck near Russia’s Kamchatka Peninsula on July 30, generating tsunami waves up to 4 meters. Coastal areas, including Severo-Kurilsk, experienced three waves, with residents safely evacuated. No fatalities have been reported, though structural damage assessments remain ongoing. The event bears similarities to the 1952 Kamchatka earthquake, which caused devastating 18-meter tsunamis. Japan’s Kuji Port recorded the highest wave at 1 meter, consistent with historical data. Tsunami effects have reached as far as Hawaii and Tonga, prompting evacuations but no injuries. Experts attribute the prolonged impact to the earthquake’s scale, tsunami direction, and Earth’s rotation. The Japan Meteorological Agency warns of continued elevated tsunami activity for at least another day. Complex seabed conditions near Kamchatka further challenge accurate predictions.
