What Happened
A 7.7-magnitude earthquake struck northern Japan on April 20, 2026, prompting tsunami alerts for waves up to three meters. An 80-centimeter wave hit Kuji port in Iwate, but no major damage occurred. Viral videos showed massive 2011 tsunami waves engulfing Ishinomaki neighborhoods, falsely captioned as current events; reverse image searches trace them to March 11, 2011, post-9.0 quake footage.
Why You Should Care
It trains you to spot recycled panic porn so you don't fall for the next viral lie during real disasters.
📚 The Basics
A reverse image search uses key frames from a photo or video to find matches across the web, revealing originals and dates. Tsunami alerts warn of incoming waves after quakes, based on magnitude and location; Japan's system is world-class due to frequent seismic activity. The 2011 Tohoku quake was 9.0 magnitude, generating 10-meter waves that killed 18,500 and melted Fukushima reactors—way deadlier than routine tremors.
🧠 Look Smart At Dinner
Say This
Social media's recycling 2011 Fukushima footage for every Japan quake shows how disaster porn never dies.
Context
Japan gets over 1,500 quakes yearly, so old clips from the 9.0 Tohoku event resurface constantly, fooling billions of views.
Avoid Saying
'Social media spreads fake news fast' — that's obvious; specify it's the same 13-year-old tsunami clip dusted off for profit clicks.
