“ChattingWith” Prof. Maurizio Fedi & Dott. Gianluca Gabbriellini – NEW TRENDS OF INTERPRETATION FOR POTENTIAL FIELDS

Potential fields are passive methods. They are based on the measurement of the Earth’s natural gravimetric and magnetic fields. In gravimetry, geophysicists measure the vertical component of the gravitational acceleration vector with great precision. In the case of magnetism, it is possible to measure the three components of the magnetic field vector or, more commonly, a single component called the total field. It refers to the direction of the main field that originates in the liquid outer core of the Earth…

The past is the key to the future: what we have done and we are planning to do

I membri della University of Naples Federico II SEG Student Chapter, sono lieti di invitarvi al webinar “The past is the key to the future: what we have done and we are planning to do”.

Durante l’evento, il nuovo board della SEG Student Chapter illustrerà tutte le attività che sono state svolte nel biennio 2019/2020 ed i progetti relativi a questo nuovo anno. In particolare, una parte del webinar sarà dedicata alla presentazione dei risultati preliminari relativi alle indagini geofisiche condotte durante il corso “SEG Geophysics Field Camp in Southern Italy 2020”.

EAGE E-Lecture: Virtual Seismology: monitoring the subsurface with virtual sources and recivers by Kees Wapenaar

This E-Lecture introduces virtual seismology: monitoring the subsurface with virtual sources and receivers, which is a new methodology to create virtual sources and virtual receivers in the subsurface from reflection measurements at the earth’s surface. Unlike in seismic interferometry, no physical instrument (receiver or source) is needed at the position of the virtual source or receiver. Moreover, no detailed knowledge of the subsurface parameters and structures is required: a smooth velocity model suffices. Yet, the responses to the virtual sources, observed by the virtual receivers, fully account for multiple scattering. This method is not only useful for reflection imaging but is has also large potential for monitoring induced seismicity, characterizing the source properties and forecasting the response to potential future induced earthquakes. This will be demonstrated with numerical models and preliminary real-data results.​
