A major challenge in subaqueous paleoseismology is to understand the relationship between an earthquake/tsunami and a sedimentary event recorded in drillcores. Expedition 381 of the International Ocean Discovery Program was dedicated to the development of the Corinth Rift, and its drilled cores provide a potentially important resource to better understand depositional mechanisms of sedimentary events within changing open marine to (semi-)isolated environments. To achieve this, we analyse U-channels and spatula samples from the topmost part (0-65 m below seafloor maximum depth) of cores M0078B and M0079A (~0-25 ka), using high-resolution X-Ray microtomography in combination with grainsize, magnetic and XRF measurements. Structures and grain array are resolved down to 12 µm in voxel size, characterizing the geometry of the basal surface of homogenite+turbidite sedimentary events, and the internal base-upwards evolution at high-resolution scale. The analysed events suggest these types of deposits are more complex than previously proposed, especially at the transition between the basal coarse turbidite sub-unit and the fine-grained homogenite upper sub-unit, as well as within the homogenite. Combined with the other observations and parameters, X-ray microtomography reinforces the interpretation of the Corinth HmTu deposits as having predominantly originated from paleoearthquake or paleotsunamis effects, despite subtle differences according to depositional environment. 1-Introduction Over previous decades, the discipline of "subaqueous paleoseismology" developed with the aim of contributing efficiently to earthquake hazards assessment (e.g. McCalpin, 2009). This approach needs to build on a tripartite relationship between 1) a sedimentary event bed 2) an earthquake with or without an associated tsunami wave, occasionally reported or recorded for historical times, and 3) an identified active fault, with possibly a localized rupture. Such paleoseismological methods are applied, event-by-event, to sedimentary records (either marine or lacustrine) that can span as much as tens of thousands of years (e.g.

“…With the advance of computational fluid dynamics (CFD) simulations, seiching can be modelled relatively easily on computers. Past work show a range of interest from modelling the fundamental modes of seiching oscillations [7] [8] [9] to further investigation of complex wave behavior due to non-linear interactions [10] [11].…”

Seiching is a common phenomenon in nature where a large body of water exhibits periodic behavior. First, we set up water oscillations in a tank and measure its oscillation period. Then we use OpenFOAM to simulate the oscillation behavior of the water waves in a 3D mesh with the same dimensions as the tank used in the experiment. Applying the Fourier transformation on the velocities calculated from OpenFOAM, we identify the period of the fundamental mode of oscillation. The result from the measurements and the simulations are presented and then compared with solutions from linearized shallow water equations. The experimental measurements, numerical simulations and SWE solutions show good agreement.
