“…The failure process leading to MTC emplacement can be externally preconditioned and triggered by earthquakes and oversteepening of the slope (i.e. geometric preconditioning effects) (Clare, Clarke, Talling, Cartigny, & Pratomo, 2016;Masson, Wynn, & Talling, 2010;Nisbet & Piper, 1998;O'loughlin & Lander, 2003;Talling et al, 2014). In additional to being stratigraphically important, the passage and emplacement of MTCs can damage seabed infrastructure and can trigger tsunami (Harbitz, Løvholt, & Bungum, 2014;Shipp, 2004).…”

“…This slumped region could be associated with the steep seafloor slopes and the extreme shaking yielded by the 1943-1953 seismic crisis. This doesn´t seem to be the source of the main tsunami of 1946, but could be related with the minor tsunamis documented several days after the main shock (Lynch & Bodle, 1948;Lander et al, 2002;O'Loughlin & Lander, 2003).…”

“…The sources of the August 4 th , 1946 large tsunami and subsequent smaller tsunamis remains unknown after several studies from seismological point of view (Heck, 1947;Lander, 1997;Dolan et al, 1998;O'Loughlin & Lander, 2003;Gailler et al, 2015;Grilli et al, 2016). Based on the places impacted by the tsunami, Dolan and Wald (1998) suggested that it was probably northward, and the seafloor shows an apparent vertical step (see Figs.…”

“…The northern Hispaniola region has suffered several disasters as the historic large earthquake of 1842 (McCann, 2006) and the seismic crises of 1943-1953(Russo and Villaseñor, 1995Dolan et al, 1998;Dolan and Bowman, 2004). In addition, after the event of August 4 th , 1946 a tsunami struck the Bahía Escocesa causing significant damages (O'Loughlin and Lander, 2003 and references therein). Tsunami simulations carried out in the northern coast of Hispaniola have provided important level of tsunami hazard in case of large tsunamigenic events nucleated in the North American-Caribbean (NOAM-CARIB) boundary plate.…”

Submarine morpho-structure and active processes along the North American-Caribbean plate boundary (Dominican Republic sector)

The northern margin of Hispaniola records the oblique collision/underthrusting of the Bahamas Carbonate Province with the island-arc. Due to the collision, northern Hispaniola has suffered several natural disasters caused by major earthquakes and tsunamis, such as the historic earthquake of 1842, the tsunami caused by earthquake-driven slumping in 1918 in the Mona Passage, the seismic crisis of 1943-1953 with five events of M>7.0 or the seismic crisis of 2003 with a main shock of M6.3 and a large aftershock of M5.3. Using new swath multibeam bathymetry data and vintage single-and multi-channel seismic profiles, we have performed a regional scale analysis and interpretation of the shallow surface and active processes along the northern margin of the Dominican Republic. We have identified three morphostructural provinces: a) the Bahamas Banks, b) the Hispaniola Trench and c) the Insular Margin, which are divided into two tectonic domains, the Collision Domain and Underthrusting Domain. The southern slope of the Bahamas Carbonate Province shows a very irregular morphology produced by active erosive processes and normal dip-slip faulting, evidence of an extensional tectonic regime and margin collapse. This collapse is of major extent in the Oblique Collision Domain where there are erosive and fault escarpments with higher dip-slip fault throws. The Hispaniola Trench, is formed by the Caicos and Hispaniola basins in the underthrusting domain, and by the Santisima Trinidad and Navidad basins in the Oblique Collision Domain. They have a flat seafloor with a sedimentary filling of variable thickness consisting of horizontal or sub-horizontal turbiditic levels. The turbiditic fill mostly proceeds from the island arc through wide channels and canyons, which transports sediment from the shelf and upper slope. The Insular Margin comprises the Insular Shelf and the Insular Slope. The active processes are generated on the Insular Slope where the Northern Hispaniola Deformed Belt is developed. This Deformed Belt shows a very irregular morphology, with a WNW-ESE trending N verging imbricate thrust-and fold system. This system is the result of the adjustment of the oblique collision/underthrusting between the North American plate and the Caribbean plate. In the Oblique Underthrusting

“…It is also noteworthy that thousands of incidences of seaquakes are known (e.g. [5][6][7][8][9][10]), but unfortunately, only a very restricted number of them are listed in the casualty reports like Lloyd's List [8].…”

The Generation of Seaquakes and its Impact on Floating Bodies

A seaquake is a strong vertical shock experienced on board a floating body at sea (e.g. ship) during a seismic event, but its generation mechanism and effects on structures have not been fully understood yet. Here, in order to better comprehend the physical process associated with seaquakes, dynamic wave propagation in a seabed-seawater system is studied. From the linear elastodynamic and nonlinear hydrodynamic wave equations, the time-dependent displacements or velocities in the system are quantitatively evaluated. It is analytically shown, for instance, that in a one-dimensional framework, wave interaction may generate resonance of the solid-liquid system or a nonlinear wave of velocity discontinuity (vertical shock) may propagate in liquid. Earlier hydrodynamic analyses of motion responses of a floating body to a seaquake usually assume a potential flow, but such an assumption may not be able to offer a physically more precise description of the generation of seaquakes and their impact on structures.
