But to improve the resolution of current seismic tomographic models, seismologists need to take into account the full complexity of wave propagation using numerical simulations, known as full-waveform inversion, says Ebru Bozdag, assistant professor in the Geophysics Department at the Colorado School of Mines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Earthquakes do more than buckle streets and topple buildings.
