Seismic Radiation From Simple Models of Earthquakes

We review some basic features of shear wave generation and energy balance for a 2D antiplane rupture. We first study the energy balance for a flat fault, and for a fault that contains a single localized kink. We determine an exact expression for the partition between strain energy flow released from the elastic medium surrounding the fault, radiated energy flow and energy release rate. This bal...

Analogue earthquakes and seismic cycles: experimental modelling across timescales

Relocating a Cluster of Earthquakes Using a Single Seismic Station

Coda waves arise from scattering to form the later arriving components of a seismogram. Coda-wave interferometry (CWI) is an emerging tool for constraining earthquake source properties from the interference pattern of coda waves between nearby events. A new earthquake location algorithm is derived which relies on coda-wave-based probabilistic estimates of earthquake separation. The algorithm ca...
