On the Potential of 3D Transdimensional Surface Wave Tomography for Geothermal Prospecting of the Reykjanes Peninsula

Rahimi Dalkhani, A. (author), Zhang, Xin (author), Weemstra, C. (author)

Seismic travel time tomography using surface waves is an effective tool for three-dimensional crustal imaging. Historically, these surface waves are the result of active seismic sources or earthquakes. More recently, however, surface waves retrieved through the application of seismic interferometry have also been exploited. Conventionally, two...

Green’s function representations for Marchenko imaging without up/down decomposition

Wapenaar, C.P.A. (author), Snieder, Roel (author), de Ridder, Sjoerd (author), Slob, E.C. (author)

Marchenko methods are based on integral representations which express Green’s functions for virtual sources and/or receivers in the subsurface in terms of the reflection response at the surface. An underlying assumption is that inside the medium the wave field can be decomposed into downgoing and upgoing waves and that evanescent waves can be...

2D body-wave seismic interferometry as a tool for reconnaissance studies and optimization of passive reflection seismic surveys in hardrock environments

Chamarczuk, Michał (author), Malinowski, Michał (author), Draganov, D.S. (author)

Despite the unrivalled spatial resolution and depth penetration of active-source seismic methods used for mineral exploration in hardrock environment, economic and environmental restrictions (e.g., source permitting) may preclude its full-scale application. In such a case, 2D passive reflection seismics can be considered a cost-effective way...

Monitoring changes inside subsurface layers using non-physical reflections retrieved from seismic interferometry

Shirmohammadi, F. (author), Draganov, D.S. (author), Wapenaar, C.P.A. (author)

Seismic interferometry (SI) is a principle for retrieving responses between two receivers using cross-correlation. After the retrieval, one of the receivers acts as a virtual seismic source whose response is retrieved at the second receiver. Correct response retrieval relies on assumptions, among other, of a lossless medium being illuminated...

The Marchenko method for evanescent waves

Wapenaar, C.P.A. (author)

With the Marchenko method, Green’s functions in the subsurface can be retrieved from seismic reflection data at the surface. State-of-the-art Marchenko methods work well for propagating waves but break down for evanescent waves. This paper discusses a first step towards extending the Marchenko method for evanescent waves and analyses its...

Systematic recovery of instrumental timing and phase errors using interferometric surface-waves retrieved from large-N seismic arrays

Weemstra, C. (author), De Laat, Janneke I. (author), Verdel, Arie (author), Smets, P.S.M. (author)

Instrumental timing and phase errors are a notorious problem in seismic data acquisition and processing. These can be frequency independent, for example due to clock drift, but may also be frequency dependent, for example due to imperfectly known instrument responses. A technique is presented that allows both types of errors to be recovered...

Shallow crustal imaging using distant, high-magnitude earthquakes

van IJsseldijk, J.E. (author), Ruigrok, Elmer (author), Verdel, Arie (author), Weemstra, C. (author)

Global phases, viz. seismic phases that travel through the Earth?s core, can be used to locally image the crust by means of seismic interferometry. This method is known as Global Phase Seismic Interferometry (GloPSI). Traditionally, GloPSI retrieves low-frequency information (up to 1 Hz). Recent studies, however, suggest that there is high...
