Advancement of Infrasound Propagation Calculation Techniques Using Mesoscale Atmospheric and Terrain Specifications
Numerical calculation of infrasound propagation paths is necessary to support accurate infrasound event identification, phase association, and source location. Predicting the details of infrasound propagation relies both on propagation models that capture the fundamental physical processes and on characterization of the propagation medium, namely the global atmosphere from the ground to altitud...
متن کاملCSLM - a modular open-source continuous space language modeling toolkit
Language models play a very important role in many natural language processing applications, in particular large vocabulary speech recognition and statistical machine translation. For a long time, back-off n-gram language models were considered to be the state-of-art when large amounts of training data are available. Recently, so called continuous space methods or neural network language models...
متن کاملInfrasound data inversion for atmospheric sounding
S U M M A R Y The International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) continuously records acoustic waves in the 0.01–10Hz frequency band, known as infrasound. These waves propagate through the layered structure of the atmosphere. Coherent infrasonic waves are produced by a variety of anthropogenic and natural sources and their propagation is controlled by ...
متن کاملA study of infrasonic anisotropy and multipathing in the atmosphere using seismic networks.
We discuss the use of reverse time migration (RTM) with dense seismic networks for the detection and location of sources of atmospheric infrasound. Seismometers measure the response of the Earth's surface to infrasound through acoustic-to-seismic coupling. RTM has recently been applied to data from the USArray network to create a catalogue of infrasonic sources in the western US. Specifically, ...
متن کاملFrontiers in Source Modeling for Near-source Ground- Motion Prediction
Accurate prediction of the intensity and variability of strong ground motions for future large earthquakes depends on our ability to simulate realistic earthquake source models. While there has been considerable progress in characterizing the complexity of earthquake ruptures, recent devastating earthquakes have exhibited rather unexpected behavior. Moderate-size events occurred with surprising...
