Abstract We document the arrival of seismic energy in the core shadow zone up to large distances beyond 150° more than 100 s prior to the core phases. Numerical simulations of the energy transport in an established heterogeneity model show that scat

We present SeisMIC, a fast, versatile, and adaptable open-source software to estimate seismic velocity changes from ambient seismic noise. SeisMIC includes a broad set of tools and functions to facilitate end-to-end processing of ambient noise data,

We explore the ambient noise wave field recorded on different optical fibers interrogated during distributed acoustic sensing (DAS) campaigns in Iceland and Germany. DAS is a relatively new technology that allows for measurements of acoustic strain s

Mt. St. Helens is an explosively erupting volcano located in close vicinity to major metropolitan centres on the US Westcoast. In recent history, Mt. St. Helens erupted twice, in 2004 and 1980, causing more than 50 fatalities and over one billion USD

The basis of all serious efforts to reduce greenhouse gas emissions is an inventory of the emissions caused by the various activities of an organisation. The Greenhouse Gas Protocol provides the guideline for establishing such an inventory. The Germa

In rocks and concrete, dynamic excitation leads to a fast softening of the material, followed by a slower recovery process where the material recovers part of its initial stiffness as a logarithmic function of time. This requires us to exit the conve

Seismic energy that follows the theoretical arrival time of the Pdiff phase is usually regarded as Pdiff coda. This implies its generation by scattering of diffracted P-waves. Such waves can theoretically be observed in the core shadow from 100° up

We investigate the flow field and deformation in the mantle wedge and subslab mantle beneath the Kuril-Kamchatka subduction zone using seismological data from a recently deployed seismic network around the Klyuchevskoy Volcanic Group (KVG) complement

Earthquakes introduce long-lasting transient mechanical damage in the subsurface that can take years to recover to a new elastic steady-state. The associated transient perturbation of the elastic moduli can cause postseismic hazards such as enhanced

SUMMARYGround shaking induced by earthquakes often introduces transient changes in seismic velocity monitored with ambient noise. These changes are usually attributed to relaxation behaviour following the coseismic damage in the subsurface and are of
