This 8 minute video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different places. Magnitudes are based on a logarithmic scale (base 10). What ...

according to Ground Motion Visualization. Seismic stations from South Florida to Maine picked up the ever-so-brief movement, data shows. “Once the earthquake waves are far enough away from the ...

Soon a little bit of foam rubber along the crack (the fault) will break and the two pieces will suddenly slip past each other. That sudden breaking of the foam rubber is the earthquake. That's what ...

"Those are important projects that have collected ground motion records gathered from extensive recordings of earthquakes from stations all over the world," Pretell said. "Our project benefited ...

The system uses ground-motion sensors to detect earthquakes that have already started and estimates their size, location, and impact. When it detects a significant magnitude, the system issues a ...
