EMC IRIS Earth Model Collaboration
A repository of Earth models with the aim of providing the research community with access to various Earth models, visualization tools for model preview, facilities to extract model data/metadata and access to the contributed processing software and scripts.
EARS EarthScope Automated Receiver Survey
The EarthScope Automated Receiver Survey (EARS) calculates bulk crustal properties of IRIS stations using receiver functions. Originally developed at the University of South Carolina, EARS continuously monitors for new events and stations updating the database when new candidate data are found.
EMC-DNA09 Finite-frequency P- and S-velocity models for the western United States
DNA09, Obrebski, Allen, Xue & Hung (2010) , model is obtained through the body wave finite frequency tomographic inversion of the available EarthScope-USArray data recorded from January 2006 to July 2009.
EMC-GyPSuM a global 3-D model of mantle shear wave (S) and compressional (P) speeds
GyPSuM, Simmons, Forte, Boschi & Grand (2010) , is a tomographic model of mantle seismic wave speeds developed through simultaneous inversion of seismic body wave travel times and geodynamic observations.
EMC-HMSL-P06 a global compressional velocity model of the mantle from cluster analysis of long-period waveforms
HMSL-P06, Houser et al. (2008) , is an isotropic P velocity model with 18 layers (approximately 100 km thickness in the upper mantle and 200 km in the lower mantle) and 2578 blocks in each layer (approximately 4 degree equal area blocks at the equator).
EMC-LLNL-G3Dv3 a global P wave tomography model based on regional and teleseismic travel times
Simmons, Myers, Johannesson & Matzel (2012) , is a global-scale model of the crust and mantle P-wave velocity with regional-scale details. The model is parameterized using a spherical tessellation with node spacing of ~1 degree in the upper mantle and ~2 degrees in the lower mantle.
EMC-NWUS11-P A 3-D P-wave tomography model for the northwestern United States
A 3-D P-wave tomography model for the northwestern United States, James et al. (2011) . The P-wave inversion for NWUS11-P is based on a total of 79,212 rays from 461 teleseismic events, with typical bandpass filter range of 0.5-1.5 Hz. The percent velocity perturbations reported by this model are insensitive to the starting 1-D reference model.
EMC-Taiwan.TTT.KWR.2012 3D P-wave velocity model of Taiwan from travel-time tomography
Taiwan.TTT.KWR.2012 (Kuo-Chen, Wu & Roecker, 2012) is based on a travel-time tomographic method from active- and passive-source experiments of Taiwan Integrated Geodynamic Research (TAIGER) and other permanent seismic networks. Totally, ~2800 stations are used.
EMC-Taiwan.TTT.KWR.2012-Supplemental Supplemental information on Earth model Taiwan.TTT.KWR.2012
Taiwan.TTT.KWR.2012 (Kuo-Chen, Wu & Roecker, 2012) is based on a travel-time tomographic method from active- and passive-source experiments of Taiwan Integrated Geodynamic Research (TAIGER) and other permanent seismic networks. Totally, ~2800 stations are used. This page contains supplemental information on this model’s resolution.
EMC-wUS-SH-2010 P and S teleseismic body-wave tomography of the western United States
Teleseismic travel-time residuals from the EarthScope Transportable Array and more than 1700 additional stations are inverted for 3-D velocity perturbations. The inversion uses frequency-dependent 3-D sensitivity kernels to map travel-time residuals, measured in multiple frequency bands, into velocity structure.
