seismic waves造句怎么写

Scientists study the Earth and natural disasters through the science of seismology –how seismic waves move through the Earth –and seismometers are their most important tool.

Scientists assign a magnitude rating to earthquakes based on the strength and duration of their seismic waves.

A seismograph produces wavy lines that reflect the size of seismic waves passing beneath it.

This estimation relied on seismological techniques measuring the first seismic waves recorded, a method that lends itself to underestimation when a quake exceeds a magnitude of 8.5.
