Liu, J. (author), Draganov, D.S. (author), Ghose, R. (author)High-resolution reflection seismics is a powerful tool that can provide the required resolution for subsurface imaging and monitoring in urban settings. Shallow seismic reflection data acquired in soil-covered sites are often contaminated by source-coherent surface waves and other linear moveout noises (LMON) that might be caused by, e.g.,...journal article 2018

Harmankaya, U (author), Kaslilar, A. (author), Wapenaar, C.P.A. (author), Draganov, D.S. (author)Unexpected geological structures can cause safety and economic risks during underground excavation. Therefore, predicting possible geological threats while drilling a tunnel is important for operational safety and for preventing expensive standstills. Subsurface information for tunneling is provided by exploratory wells and by surface...journal article 2018

Draganov, D.S. (author), Hunziker, J.W. (author), Heller, H.K.J. (author), Gutkowski, Karin (author), Marte, Fernando (author)Artworks are an inseparable part of the cultural heritage of societies and provide us with a unique look at cultural developments through time and space. For the best possible conservation, it is paramount to know the constituent materials, condition, and construction techniques of the objects (e.g. painting on wood, fresco, sculpture). Such...journal article 2018

Casas, Augusto (author), Mikesell, D (author), Draganov, D.S. (author), Lepore, Simone (author), Badi, Gabriela (author), Franco, Luis (author), Gomez, Martin (author)We applied the seismic interferometry technique to characterize the subsurface velocities of the Planchón-Peteroa Volcanic Complex, Argentina-Chile, down to a depth of about 350 m. Ambient seismic noise data were recorded by an array of six stations deployed in the eastern flank of the current active volcano of this volcanic complex—the Peteroa....journal article 2018

(author)We present the results of adapting seismic interferometry (SI) for reflection imaging in mineral exploration. We use a unique dataset of one-month ambient-noise recordings acquired with large-N array (~1000 receivers) deployed in a regular grid (50 m receiver interval, 200 m line interval) directly above the known mineralisation and underground...conference paper 2018

Cheraghi, Saeid (author), White, Donald J. (author), Draganov, D.S. (author), Bellefleur, Gilles (author), Craven, James A. (author), Roberts, Brian (author)Seismic reflection interferometry has recently been tested in a few resource-exploration applications. We have evaluated passive seismic interferometry results for data from the Aquistore CO<sub>2</sub> storage site, Saskatchewan, Canada, with the objective of testing the method's ability to image the subsurface geology and its potential for...journal article 2017

(author)Obtaining new seismic responses from existing recordings is generally referred to as seismic interferometry (SI). Conventionally, the SI responses are retrieved by simple crosscorrelation of recordings made by separate receivers: one of the receivers acts as a ‘virtual source’ whose response is retrieved at the other receivers.When SI is applied...journal article 2017

(author)The knowledge of the distribution of leachate and gas in a municipal landfill is of vital importance to the landfill operators performing improved landfill treatments and for environmental protection and efficient biogas extraction. We have explored the potential of using the velocity fields of seismic S- and P-waves to delineate the wet and...journal article 2016

Nishitsuji, Y. (author), Minato, S. (author), Boullenger, B. (author), Gomez, M (author), Wapenaar, C.P.A. (author), Draganov, D.S. (author)We have developed an application of passive seismic interferometry (SI) using P-wave coda of local earthquakes for the purpose of crustal-scale reflection imaging. We processed the reflection gathers retrieved from SI following a standard seismic processing in exploration seismology. We applied SI to the P-wave coda using crosscorrelation,...journal article 2016

Nishitsuji, Y. (author), Ruigrok, E (author), Gomez, M (author), Wapenaar, C.P.A. (author), Draganov, D.S. (author)Obtaining detailed images of aseismic parts of subducting slabs remains a large challenge for understanding slab dynamics. Hypocenter mapping cannot be used for the purpose due to the absence of seismicity, whereas the use of receiver functions might be compromised by the presence of melt. Global tomography can be used to identify the presence...journal article 2016

Kaslilar, A. (author), Harmankaya, U. (author), Wapenaar, C.P.A. (author), Draganov, D.S. (author)Inspired by a technique called seismic interferometry, we estimate the location of a scatterer using scattered waves. We isolate the scattered wavefield and evaluate the result of correlating scattered waves at different receiver locations. The cross-correlation eliminates the travel path between a source and a scatterer, making the estimation...conference paper 2015
