A: Hey! Did you hear about that earthquake near Russia? It was pretty big, right?
B: No! Really? What happened?
A: Yeah! Japanese researchers studied it. They think huge earthquakes, like magnitude 9 ones, might happen more often than we thought!
B: Wow! Like, shorter time between them?
A: Exactly! They looked at the 2025 earthquake and compared it to one from 1952. They happened in almost the same place.
B: That’s scary! What did they find?
A: They think something called "overshoot" happened. It’s when the earthquake slips more than it should.
B: Overshoot? What does that mean?
A: It means the earthquake released strain that hadn't been released from the last big one! Like it caught up.
B: So, does this mean another big one could happen near Japan?
A: Potentially! The researchers said it could happen along the Nankai Trough and other areas.
B: Oh no! Should we be worried?
A: Professor Yagi said we shouldn't let our guard down. It could happen anytime. We need to be prepared!
B: Okay, good point. Maybe I’ll check my emergency kit. Thanks for the heads up!

Summary
Japanese researchers found a large earthquake near Russia may indicate that magnitude 9+ earthquakes could occur more frequently than previously thought. The study suggests "overshoot" – strain buildup from past events – could trigger future quakes, potentially near Japan’s Nankai Trough.
