Distant quakes trigger undersea landslides in Gulf of Mexico. Alternatively, Fan says “the wave characteristics of these large earthquakes [may be] too different than the triggering earthquakes.”,Submarine landslides appear clumped together in the northwestern corner of the Gulf of Mexico, which corresponds to the coastal waters of Texas. and earth science while inspiring careers in geophysics.IRIS staff and subawardees oversee the construction, Fan and his scientific team, utilized the.Out of the 85 underwater slides that the team identified, 10 occurred without an apparent triggering factor. By analyzing the data, they concluded that the signals derived from underwater ground displacements. Magnitudes of triggering earthquakes range from 4.9 to 7.3. Such massive redistributions of sediment can displace the water column.By their very nature, submarine landslides of all sizes are difficult to observe. In 2004, an.The seafloor of the Gulf of Mexico is particularly prone to landsliding as it constantly receives huge amounts of river sediments that create a steep underwater topography.According to Wenyuan Fan, lead author of the study and an Assistant Professor in the Department of Earth, Ocean and Atmospheric Science at Florida State University, the underwater landslides identified at the Gulf of Mexico pose a severe threat to coastal regions.Prof. This makes them easily identifiable to scientists like Fan.Oddly, there’s no obvious relationship between key characteristics of the triggering earthquake—magnitude, depth or style—and the resulting landslides. Depths range from 12 to 69 kilometers. webinars, past event materials. Because this area is prone to landslides, Fan says, “I hope our study can help inform the planning efforts and communities along the Gulf coast to reduce the foreseeable risks.” He continues, “No one wants another BP oil spill in the Gulf, and this is actionable science given [that the region] is prone to submarine landslides.”.Fan, W., McGuire, J. J., & Shearer, P. M.. ( 2020). Ten of these landslides failed spontaneously while the remaining 75 were dynamically triggered by passing seismic surface waves from distant earthquakes with magnitudes as small as ∼5.
IRIS provides management of, and access to, observed Called submarine landslides, they can move millions of tons of sediment and rock hundreds of kilometers in one fell swoop. Recently searched locations will be displayed if there is no search query. Such a system would require the installation of seismographs on the seafloor and, potentially, it could help prevent a disaster such as an oil spillage.The spillway of Whaley Bridge dam which partially...At least 11 people have been reported dead and ma...A significant step has been made for the completi...A major highway in India was closed due to a larg...Authorities urged people to stay away from cliffs...According to a new study, the vast proportion of...Create a free account and view content that fits your specific interests in geotechnical engineering.Geoengineer.org uses third party cookies to improve our website and your experience when using it.The International Information Center for Geotechnical Engineers,oil platform sank off the coast of Louisiana,Whaley Bridge dam: The spillway that partially collapsed is replaced,Landslides struck Nepal: At least 11 casualties,New tunnel in Swiss Alps changes railway transport in Europe,Rockslide caught on camera blocks a major highway in India,Cliff collapse in Jurassic Coast, United Kingdom,Study presents new insights about the depletion of the world's groundwater storages,Bentley System announces availability of OpenGround Cloud: The secure, cloud-based collaboration platform for geotechnical data management,Announcing the Publication of the 2020 Geotechnical Business Directory,Advantages of pseudo-3D consolidation analysis with SVSOLID, SVFLUX,New freeware on stress and settlement modelling,Helical pile solution for environmentally sensitive areas,How to create 3D dykes using SOIVISION 3D extrusion tools. and derived data for the global earth science community.This includes ground motion, atmospheric, infrasonic, In a new study, scientists have identified 85, previously unknown, submarine landslides in the Gulf of Mexico that occurred in a 7-year period (from 2008 to 2015).The results of the study have been recently,The impact of underwater slides can be significant.
