SCALE EFFECT IN SEISMOTECTONICS

Геодинамика и тектонофизика, 2015
This publication consolidates and analyses experimental data in a wide range of scales in seismotectonics and geo­mechanics, from a micro-size seismic event (an earthquake focus of a few centimetres) to a mega earthquake.

The moment method for the seismic inverse problem

, 2020
We propose a new mathematical moment technique for the inverse problem of wave propagation in an inhomogenous (half-space) medium in the acoustical wave field Born approximation by using the analytical regulariazation scheme of the theory of quantum fields .

Seismic anisotropy in siliciclastic reservoir rocks [PDF]

, 2006
The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

Relationship between moment rate of short-term slow slip events and moment rate of tectonic tremors in a frequency range of 1–10 Hz

Earth, Planets and Space
Simultaneous activations of slow slip events (SSEs) and tectonic tremors are observed along subduction zones, and collectively referred to as episodic tremor and slip (ETS).

Seismic data reconstruction method using generative adversarial network based on moment reconstruction error constraint

Science Progress
The seismic data acquired are usually spatially undersampled due to the constraints of the field acquisition environment. However, the removal of multiple waves, offsets, and inversions requires high regularity and integrity of seismic data.

Definition of seismic and tsunami hazard scenarios by exploiting EU-India Grid e-infrastructures [PDF]

, 2012
Seismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude.

Displacement based seismic design of steel moment resisting frame structures (DiSTEEL)

, 2015
The DiSTEEL research project has developed a set of practical performance-based design guidelines for steel moment-resisting frame structures by developing both a direct displacement-based design (DBD) procedure and performance criteria applicable to ...

Seismic Response of Shield Tunnel with Double-Layer Lining

Applied Sciences
A shield tunnel is an assembly structure composed of connecting bolts and segments, generally considered to have good seismic performance. However, there is still a possibility of damage occurring in shield tunnels under strong seismic action. Therefore,

Seismic Moment-Felt Area Relation for Seismic Hazard Scenario Characterization.

, 2008
A macroseismic approach for the determination of the seismic moment of historical earthquakes is proposed, aimed at a correlation of the damage scenario to the size of the earthquake through a seismic moment-felt area ...
