This paper discusses apparent anelastic (combination of intrinsic and scattering) attenuation
of 5% damped response spectral accelerations (SA) associated with the geometric …

Empirical models of geometrical‐, Q‐, t‐star, and kappa‐type attenuation of seismic waves
and ground‐motion prediction equations (GMPEs) are viewed as cases of a common …

Many observations of seismic waves from local earthquakes are interpreted in terms of the
frequency-dependent quality factor Q\left (f\right)= Q_ 0 f^ η Q f= Q 0 f η, where η is often …

In a companion article, argued that construction of distance‐and frequency‐dependent
models for seismic‐wave amplitudes should include four general elements:(1) a sufficiently …

The M w 7.5 earthquake that struck central Papua New Guinea in 2018 was the largest
event ever recorded in the region with modern seismic instruments. The ground motions …

Seismic codas are usually characterized by the values of coda Q (Q c). However,
interpretation of this quantity is often tricky because of its frequency dependence and acute …

This dissertation addresses several important aspects of observational earthquake
seismology: 1) methods for data management and processing large datasets, 2) analysis of …

Anelasticity and heterogeneity in the Earth decreases the energy and modifies the dominant
frequency of seismic wavetrains as they travel through the Earth. These phenomena are …
