摘要

The United States will be hit by a major earthquake causing hundreds of fatalities within my lifetime. Whether it will be in 20 years, 2 years, or tomorrow, we do not know. Such an event will prompt the country to implement a public earthquake early-warning system, giving people seconds or minutes to prepare for the shaking. Rather than waiting until the next big quake galvanizes political action, I believe that we must build an alert system now. Earthquake early-warning technology is proven. Japan leads the way. When the magnitude-9 Tohoku-Oki earthquake hit the northeast of the country in March 2011, an automatic warning was issued within seconds. Trains stopped, students took shelter under desks, sensitive manufacturing equipment was paused and hazardous chemicals were isolated. Lives and money were saved. China, Taiwan, Mexico, Turkey and Romania also issue earthquake alerts.
