An Integrated Approach to Locating Undetected Off-Shore Small Magnitude Seismic Sources
Abstract
The publicly available earthquake record contains a plethora of information regarding seismic sources across the globe. However, smaller magnitude seismic sources are generally not kept on record. Small magnitude seismic sources can indicate many different occurrences such as earthquakes, landslides, ordnance, or commercial human interaction. An integrated method, using the existing Automated Event Location Using a Mesh of Arrays (AELUMA) scheme combined with a multi-layered deep neural network machine learning algorithm, can allow for more accurate seismic source location with lower uncertainty. More accurate low magnitude seismic source locations can be directly applied to seabed instability, where off-shore landslides, for instance, create obstacles for subsurface naval warfare. Additionally, accurate seismic source locations can affect decision making with respect to seafloor infrastructure and commercial interests.
