Inventor Jerry Paros posed for a photograph for an article in the publication Nature about his invention -- an ultra precise quartz sensor that could contribute to an early-warning system designed to detect shifts in the sea floor that cause tsunamis.

Tsunamis are caused primarily by earthquakes that occur in the seafloor, since rapid shifts in elevation can generate waves that cross oceans in a matter of several hours. In 2011, a massive tsunami hit northern Japan following a magnitude 9.0 earthquake off the coast, resulting in the meltdown of nuclear reactors at the Fukashima Daiichi Nuclear Power Plant.
