An 8.8-magnitude earthquake off Russia’s far eastern coast has led to widespread tsunami warnings across the Pacific. In Hawaii, traffic jams and sirens signalled urgent evacuations. Social media was flooded with real-time updates from locals, including videos of gridlock and blaring alarms. Japan, Alaska, and California are also on high alert. Emergency authorities are warning of repeated waves and have urged people to reach higher ground. Ports, airports and highways are being cleared as a precaution.
