Pletser et al. performed a seismic-refraction survey on Devon Island with the goal of assessing the feasibility of astronauts carrying out such operations on Mars to detect subsurface water. We demonstrate that the seismic analysis is fundamentally flawed. The survey performed in this test will likely bear little resemblance to future crewed geophysical surface operations, and better methods ex...

The period of vibration is a fundamental parameter in the force-based design of structures as this parameter defines the spectral acceleration and thus the base shear force to which the building should be designed. This paper takes a critical look at the way in which seismic design codes around the world have allowed the designer to estimate the period of vibration for use in both linear static...

Masonry structures are complex systems that require a thorough and detailed knowledge and information regarding their behaviour under seismic excitations. Appropriate modelling of a masonry structure is a prerequisite for a reliable earthquake resistant design or assessment. However, modelling a real structure to a robust quantitative (mathematical) representation is a very difficult, complex a...

Ice stratigraphy from deep-penetrating radar data collected during the 2002 US International Trans-Antarctic Scientific Expedition (US-ITASE) traverse shows evidence of a significant erosion surface and drift-filled basin related to a previously undiscovered 1400m subglacial mountain between Hercules Dome (878420 S, 1088W) and South Pole. The 3MHz radar profile crosses three subglacial mountain...

An appropriate velocity model from well logs is a key issue in the processing and interpretation of seismic data. In deep borehole located central part Polish Outer Carpathians, sonic measurements were inadequate for purposes due to poor quality data gaps logging. Multiple regression (MR) modified Faust equation proposed log. MR estimated P-wave slowness as dependent variable on basis sets vari...

Bottom simulating reflections (BSRs) interpreted in seismic data are one of the most used indicators for presence gas hydrates. In numerous hydrate provinces, including Hikurangi margin, east New Zealand, distinct and anomalous gaps reflectivity punctuate otherwise continuous BSRs. We undertake a stratigraphic structural interpretation dense grid two-dimensional reflection to investigate possib...

We discuss three approaches to seismic interferometry and compare their underlying assumptions. In the first approach the reflection response is reconstructed by cross-correlating the responses of many uncorrelated noise sources. In the second approach a depth image is obtained from the response of a single source, recorded by many receivers. In the third approach the Green’s function is recons...

This work uses high-quality reprocessed 2D data, tied to borehole information, address the development of North Atlantic Jurassic seaways on continental margin West Iberia. The seismic data reveal full thickness Mesozoic syn-rift strata filling deep-offshore basins in this latter region. Tectonic subsidence resulted separation seaway into distal and proximal sectors. As a result, backstripped c...
