Modelling Seismic Wave Propagation for Geophysical Imaging

Joint Use of Seismic and Electromagnetic Methods in Geophysical Surveys

Multi-channel Analysis of Surface Waves (MASW) is a seismic wave propagation method which involves the measurement of Rayleigh waves propagating along the surface of a medium. The method is non-intrusive, fast and practical and it has been successfully utilized for the in-situ evaluation of shear modulus and layer thicknesses of soils and, more recently, pavement systems. The method is also wid...

Unsupervised Learning for Geophysical Data Exploration

Unsupervised learning techniques provide a way to investigating scientific data based on automated generation of statistical models that describe the data. Because they do not incorporate a priori information, they can be used as an unbiased method to separate data into distinct types. Thus they can be used as an objective method by which to separate data into previously known classes or to fin...

An electromagnetic system for planetary geophysical exploration

The paper presents a study, carried out in the context of TESEO project (Sistema di prospezione TDEM per l’ESplorazione gEOfisica dei pianeti), for the design of a TDEM (Time Domain Electromagnetic Method) system suitable for planetary subsurface exploration. The TDEM technique has been selected since it is based on the parameter of electrical conductivity, which is generally capable of discrim...

Geophysical investigations and modeling of seismic response for a seismic microzoning study in Caracas, Venezuela

One of the most important natural hazards that threatens Caracas, the capital city of Venezuela, is the seismic hazard, due to its location in the plate boundary zone between the South America and the Caribbean plates. There is historic evidence for several destructive earthquakes in Caracas since 1641, being the most recent one the 1967 Caracas earthquake. This magnitude 6.5 earthquake which o...
