الوصف: We present a new comprehensive visual representation of global seismic phases using AlpArray. Our AlpArray-based animations connect spatial-temporal wavefield and time-dependent array method to visualize the evolution of teleseismic phases over time. Here are the animations of a few example teleseismic events occurred during the course of AlpArray (2016-2019).

مصطلحات موضوعية: Seismology, wave propagation, simulation, subduction zone, earthquake

الوصف: The movies show wave propagation simulations that we used to model the synthetic seismograms presented in the supporting information of the manuscript "Toward waveform-based characterization of slab & mantle wedge (SAM) earthquakes" by Felix Halpaap, Stéphane Rondenay, Qinya Liu, Florian Millet, Lars Ottemöller. The two movies show the following content: ms02.mp4: The movie contains four times three panels, corresponding to twelve waveform simulations of earthquakes occurring (i, top row) in the mantle wedge, (ii, 2nd row) on the subduction interface, (iii, 3rd tow) in the slab crust, (iv, 4th row) in the slab mantle, for (a, left column) a normal-faulting focal mechanism, (b, 2nd column) a low-angle thrusting focal mechanism, (c, 3rd column) a dip-perpendicular thrusting focal mechanism. ms03.mp4: The movie contains four panels, corresponding to four waveform simulations of earthquakes occurring (i, top left) in the mantle wedge, (ii, bottom left) on the subduction interface, (iii, top right) in the slab crust, (iv, bottom right) in the slab mantle. Here the earthquakes have a thrusting focal mechanism with a 45º-dipping fault plane. The simulations shown here are computed with seismic attenuation (specified in the supporting information of the accompanying manuscript). In the movies, the simulation runs are synchronized to show the P-wave arrival at a station vertically above the earthquake at the same time. The counter in the top left corner indicates the simulation time relative to the P-wave arrival at that station. To enhance the visibility of small-amplitude wavefronts, the color intensity of the wavefronts corresponds to a logarithmic scaling of the wavefront amplitudes, with wavefront amplitudes below 0.5 % muted. The amplitudes here correspond to the norm of the displacement vector (i.e., showing particle motion in the horizontal and vertical directions).

مصطلحات موضوعية: mixed wave propagation, technical animation, longitudinal transverse waves on a string

الوصف: Adobe flash animation - requires free Adobe flash player be installed on the viewer's computer. ; Physics students study waves on a string as typical of wave motion in general. While pure longitudinal and purely transverse waves are presented in most courses, in fact most waves, even waves on a string, have a mixture of both longitudinal and transverse motions. This animation illustrations such waves.

الوصف: In these lectures I will explain the basics of microlocal analysis, emphasizing non-­elliptic problems, such as wave propagation, both on manifolds without boundary, and on manifolds with boundary. In the latter case there is no « standard » algebra of differential, or pseudodifferential, operators; I will discuss two important frameworks: Melrose's totally characteristic, or b­‐, operators andscattering operators. Apart from the algebraic and mapping properties, I will discuss microlocal ellipticity, real principal type propagation, radial points and generalizations, as well as normally hyperbolic trapping. The applications discussed will include Fredholm frameworks (which are thus global even for non­‐elliptic problems!) for the Laplacian on asymptotically hyperbolic spaces and the wave operator on asymptotically de Sitter spaces, scattering theory for « scattering metrics » (such as the « large ends » of cones), wave propagation on asymptotically Minkowski spaces and generalizations (« Lorentzian scattering metrics ») and on Kerr­‐de Sitter‐type spaces. The lectures concentrate on linear PDE, but time permitting I will briefly discuss nonlinear versions. The lecture by the speaker in the final workshop will use these results to solve quasilinear wave equations globally, including describing the asymptotic behavior of solutions, on Kerr­‐de Sitter spaces.
