Oblique collision between the Caribbean plate and the Bahama Banks has lead an eastward migration of the northern Caribbean plate boundary by successive southward jumps of major strike‐slip faults. The Septentrional‐Oriente Fault zone (SOFZ) defines the present‐day northern Caribbean plate boundary accommodating most of the eastward escape of the Caribbean plate. Here, we reevaluate the complex history of the SOFZ along the Windward Passage area between the easternmost region of Cuba and the northwest of Haiti. Based on seismic reflection and swath‐bathymetric data set we interpret the structure and tectonic pattern of the Windward Passage. The tectono‐sedimentary framework of this large strait shows contrasting patterns of deformation linked to a complex polyphase tectonic history of dominantly strike‐slip faulting. SOFZ segments offset the seismic units and yield key markers of displacement along the fault system. Our study provides structural and stratigraphic insights into the relative timing of deformation along the Windward Passage and presents new elements that constrain the southeastward jump of the north Caribbean plate boundary to its present‐day position. We propose dates for the identified seismic units based on the correlation of offshore deformation phases recorded in the Windward Passage sedimentary cover with major paleogeographic reorganization episodes described onland (Late Eocene, Late Oligocene, Middle Miocene and Late Pliocene). By restoring the offset of the seismic units, we demonstrate that at least ∼80 km of left‐lateral motion has occurred on the SOFZ, and that the SOFZ has been active since the Pliocene.
The literature regarding attacks in Networked Control Systems (NCS) indicates that covert and accurate attacks must be designed based on an accurate knowledge about the model of the attacked system. In this context, the literature on NCS presents the Passive System Identification attack as a metaheuristic-based tool to provide the attacker with the required system models. However, the scientific literature does not report countermeasures to mitigate the identification process performed by such passive metaheuristic-based attack. In this sense, this work proposes the use of a randomly switching controller as a countermeasure for the Passive System Identification attack, in case of failure of other conventional security mechanisms -such as encryption, network segmentation and firewall policies. This novel countermeasure aims to hinder the identification of the controller, so that the model obtained by the attacker is imprecise or ambiguous, in such a way that the attacker hesitates to launch covert or model-dependent attacks against the NCS. The simulation results indicate that this countermeasure is capable to mitigate the mentioned attack at the same time that it performs a satisfactory plant control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
