Overview

• The Japan Meteorological Agency revised the magnitude to 8.8, triggering tsunami alerts across Japan, the US, Canada and Latin American Pacific coasts before warnings were canceled after waves proved minor and no casualties occurred.
• Chile is keeping an active alert in 13 of its 16 regions from Arica y Parinacota to Los Lagos, while Peru continues to close 15 northern ports as a precaution.
• Mexico, though issuing no active warnings this time, underscores its coastal vulnerability identified by UNAM in seven Pacific coast states.
• Early-warning systems operated by JMA, UNGRD, Senapred and other agencies enabled the evacuation of 2,700 people in the Kuril Islands and preemptive port closures that mitigated risks.
• Seabed topography in the Pacific Ring of Fire limited recorded tsunami heights to under four meters in the Kurils and 1.3 meters in Japan, according to experts.
