Article
The role of seafloor roughness on the seismogenic behavior of subduction zones has been increasingly addressed over the past years, although their exact relationship remains unclear. Do subducting features like seamounts, fracture zones, or submarine ridges act as barriers, preventing ruptures from propagating, or do they initiate megathrust earthq...
Article
We have developed a new approach to characterize the seafloor roughness seaward of the trenches, as a proxy for estimating the roughness of the subduction interface. We consider that abrupt elevation changes over given wavelengths play a larger role in the seismogenic behavior of the subduction interface than the amplitude of bathymetric variations...
Article
Full-text available
The roughness of the subduction interface is thought to influence seismogenic behavior in subduction zones, but a detailed understanding of how such roughness affects the state of stress along the subduction megathrust is still debated. Here, we use seismotectonic analogue models to investigate the effect of subduction interface roughness on seismi...
Article
Full-text available
The Lesser Antilles subduction zone is a challenging region when it comes to unraveling its seismogenic behavior. Over the last century, the subduction megathrust has been seismically quiet, with no large thrust event recorded, which raises the question whether this subduction zone is able to produce large interplate earthquakes or not. However, tw...
Article
Full-text available
Geological estimates of vertical motions in the central part of the Lesser Antilles show subsidence on timescales ranging from 125.000 to 100 years, which has been interpreted to be caused by interseismic locking along the subduction megathrust. However, horizontal GNSS velocities show that the Lesser Antilles subduction interface is currently buil...
Preprint
Science's success and effect measures are built on a system that prioritizes citations and impact factors. These measurements are inaccurate and biased against already under-represented groups, and they fail to convey the range of individuals' significant scientific contributions, especially open science. We argue for a transition in this out-of-da...
Article
Full-text available
The 700‐km‐long Chaman fault (CF) marks the western edge of the plate boundary between India and Eurasia. Although global plate models predict 2.3–3.6 cm/yr left‐lateral motion between both plates, the fault is known to have hosted few earthquakes in historical times. Recent geodetic measurements attested the presence of aseismic slip locally. To d...

Chapter
The interface between the downgoing- and overriding plates in subduction zones can host very large earthquakes, depending on the characteristics of the subduction zone. One parameter that is thought to play a role in tuning this seismogenic behavior is the subduction interface roughness. The size and distribution of bathymetric features on the inte...

Full-text available
Tsunamigenic earthquakes pose a large hazard in subduction zones, but it is currently unclear in which - if any - tectonic setting they preferentially occur. We compile the Subduction Nature & Interconnected Tsunamigenic earthquake Characteristics (SNITCH) database with parameters on the geodynamics, megathrust seismicity, and tsunami characteristi...

Data
Data are available through the EPOS data repository. This dataset contains digital image correlation (DIC) data of eight seismotectonic analogue experiments that were performed at the Laboratory of Experimental Tectonics (LET), Univ. Rome Tre, to investigate the effect of subduction interface roughness on the seismogenic behaviour of the megathrus...
Thesis
Full-text available
Subduction zones are known for their very large earthquakes, with observed magnitudes up to MW 9.6, and are therefore studied extensively by the scientific community. The impact of such events on societies can be immense, as demonstrated by the recent MW 9.1 Tohoku (2011), MW 8.8 Maule (2010) and MW 9.2 Sumatra (2004) earthquakes, which occurred in...
Thesis
Most mega-earthquakes (i.e. earthquakes with Mw ≥ 8.5) occur along subduction mega-thrusts, the interfaces between the subducting - and the overriding plates in convergent margins. These events may have catastrophic impact on human societies due to their destructive potential. For this reason being able to predict the timing and size of these earth...
Poster
Full-text available
We have developed an experimental approach to complement numerical modeling techniques used to analyze available geological and geophysical observations and measurements of subduction earthquakes such as the 2004 Sumatra-Andaman or the 2011 Tohoku earthquakes. Main goal is to validate a kinematically and mechanically first-order scaled analogue mod...
Article
Understanding the behavior of enigmatic geomagnetic traits such as the Levant intensity high is currently challenged by a lack of full vector records of regional variations in the geomagnetic field. Here we apply the recently proposed multi-method paleointensity approach to a suite of 19 lavas from the Canary Islands dating between ∼4000 BC and 190...

Project
The lesser Antilles subduction zone has been subject of debate regarding the degree of coupling along the plate interface and the possibility of large megathrust earthquakes. Using a Bayesian approach based on GPS data, we aim to get a better estimate of the interseismic coupling and its associated uncertainties along the subduction megathrust.
