ambientnoise

Codes for ambient noise tomography of Alaska

ancc

Some scripts for ambient noise tomography (support parallel computing and auto-correlation computation)

aspect

A parallel, extensible finite element code to simulate convection in both 2D and 3D models.

auto_tanaylsis_gui

Automatic Surface Wave Two-station Dispersion Analysis (Matlab GUI)

azimuthal_anisotropy

Retrieve azimuthal anisotropy of surface waves from inter-station measurements, following Schippkus et al. 2020

bfgs_uq

cc-fjpy

A Python Package for seismic ambient noise cross-correlation and the frequency-Bessel transform method

cmse

Cartesian Meshing Spherical Earth (CMSE): A code package for generating spherical earth model mesh based on SPECFEM3D_Cartesain

convnetquake

Convolutional Neural Network for Earthquake detection and location

cpspy

Python interface for Computer Programs in Seismology

cube2sphere

Python script to map 6 cube (cubemap, skybox) faces into an equirectangular (cylindrical projection, skysphere) map.

dazimsurftomo

Direct inversion of Rayleigh wave dispersion data for 3-D azimuthal anisotropy based on ray tracing

disbatomo

eikonet

Machine learning formulation for the Factored Eikonal Equation

examples-3d

fasttrip

fd2d

2D finite-difference code for noise correlations and kernels

flexwin

The FLEXWIN software package automates the time-window selection problem for seismologists. It operates on pairs of observed and synthetic single component seismograms, defining windows that cover as much of a given seismogram as possible, while avoiding portions of the waveform that are dominated by noise.

fmtomoscripts

fwi-scal

fwi_ot

Full waveform inversion with unbalanced optimal transport distance

gcmt3d

gladm15

Visualization package for GLAD-M15.

gladm25

Visualization package for GLAD-M25.

lasif_specfem3d

This is a modified version of LASIF (LArge-scale Seismic Inversion Framework) to expand the framework for FWI using newer versions of SPECFEM3D and additional options for teleseismic configurations. !!! The code is still in development !!!

learning-aftershock-location-patterns

Training, testing, evaluation codes for learning aftershock location patterns

machine-learning

Machine learning for Project Cognoma
