Fault-Structure-Based Active Fault Diagnosis: A Geometric Observer Approach

open access: yesEnergies, 2020
Fault diagnosis techniques can be classified into passive and active types. Passive approaches only utilize the original input and output signals of the system.

Active faults and related Late Quaternary deformation along the Northwestern Himalayan Frontal Zone, India

open access: yesAnnals of Geophysics, 2003
Numerous newly-identified traces of active faults in the Himalayan foothill zone along the HFF around Chandigarh, in Pinjore Dun, along the piedmont zone of the Lower Siwalik hill front and within the Lower Tertiary hill range reveal the ...

Joint Interpretation of Geophysical Results and Geological Observations for Detecting Buried Active Faults: The Case of the “Il Lago” Plain (Pettoranello del Molise, Italy)

open access: yesRemote Sensing, 2021
We report a geophysical study across an active normal fault in the Southern Apennines. The surveyed area is the “Il Lago” Plain (Pettoranello del Molise), at the foot of Mt. Patalecchia (Molise Apennines, Southern Italy), a small tectonic basin filled by

The Relationship of Small Earthquakes to Strain Accumulation Along Major Faults in Southern California [PDF]

open access: yes, 1983
Fault-plane solutions for recent small (ML ≤ 4.6) earthquakes in the central Transverse Ranges, California, were determined using an azimuthally-varying crustal model.

A large unknown historical earthquake in the Abruzzi region (Central Italy): combination of geological and historical data

open access: yesAnnals of Geophysics, 1995
The combination of paleoseismological and historical investigation can be used to obtain a complete knowledge of past earthquakes. In Italy the 1000 year-long record of historical earthquakes provides an opportunity to compare data from the catalogue ...

Fault tolerant control based on active fault diagnosis [PDF]

open access: yesProceedings of the 2005, American Control Conference, 2005., 2005
An active fault diagnosis (AFD) method is considered in this paper in connection with a fault tolerant control (FTC) architecture based on the YJBK parameterization of all stabilizing controllers. The architecture consists of a fault diagnosis (FD) part and a controller reconfiguration (CR) part. The FTC architecture can be applied for additive faults,

Structural Characteristics and Formation Mechanism of the Earth Fissures as a Geohazard in Birjand, Iran

open access: yesApplied Sciences, 2022
Earth fissure structures are a common type of geohazard associated with geotechnical surface ruptures that can occur almost anywhere on the ground surface due to a variety of different mechanisms, and in most cases, these hazardous cracks have resulted ...

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

open access: yes, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.
