Earthquake frequency spectra are determined by fault rupture velocity, slip displacement, and rock friction
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
Geophysical studies and stochastic fault simulations confirm that earthquake frequency spectra and ground motion are governed by source properties such as rupture velocity, slip distribution, and fault friction.
