Scientists are still piecing together exactly how earthquakes trigger tsunamis—those massive, destructive waves. While they know factors like the quake’s depth and the seafloor’s movement play a role, predicting which earthquakes will spawn tsunamis remains tricky. The article also breaks down practical steps to take if a tsunami warning hits, because when seconds count, knowing what to do could save lives.

Editor’s Note: Tsunamis are rare but devastating, and understanding their triggers—or lack thereof—helps communities prepare better. This isn’t just science for science’s sake; it’s about giving people real-world tools to react when danger strikes. Plus, with climate change intensifying natural disasters, grasping these mechanics feels more urgent than ever.

A massive magnitude 8.8 earthquake struck off Russia’s eastern coast, raising fears of a devastating tsunami for tens of millions. But despite its size—one of the strongest ever recorded—it caused surprisingly little damage. Experts point to the quake’s depth, location, and swift tsunami warnings as key reasons the disaster was averted.

Editor’s Note: This story is a rare bit of good news in the world of seismic events. It highlights how preparedness, geography, and sheer luck can turn a potential catastrophe into a near-miss—and why understanding these factors matters for future disaster response. It’s a reminder that not all earthquakes are created equal, even when they’re record-breakers.

NBC News correspondent Morgan Chesky finds himself in an emotionally charged situation as he reports on the catastrophic flash floods that struck his own hometown in Texas Hill Country over the July 4th holiday. It’s a rare and deeply personal assignment for Chesky, who must balance professional detachment with the raw reality of seeing his community in crisis.

Editor’s Note: This isn’t just another disaster story—it’s a poignant reminder of how climate extremes are hitting closer to home, literally, for those covering them. Chesky’s personal connection adds a layer of humanity to the reporting, making the devastation feel more immediate and relatable. For viewers, it underscores how no one is truly insulated from extreme weather, even the people who usually document it for a living.
