There have long been attempts to apply Full Waveform Inversion FWI to land data sets because it has the potential to build higher-resolution velocity models compared to traditional ray-based model building techniches. However, several difficulties hinder the successful application of FWI to land data: cycle skipping, unreliable amplitudes, as well as source and receiver signature estimation. The Seismic Reflection Slope FWI method is capable of identifying small velocity anomalies such as gas clouds and faults, thereby producing a higher-resolution velocity model. We also note that these three methods can be combined together to form a FWI based model building strategy that produces high-resolution velocity model for land data set. Two field data examples are used to illustrate the effectiveness of this model building strategy. First, we applied the strategy to a 2D field data set acquired in Inner Mongolia. Two starting models were used, one is a simple model converted from time domain RMS velocity, and the other is from the traditional ray based model building approach. For both cases, our strategy was able to greatly improve the velocity model and the migration image. The migration image starting from the traditional ray based model had a superior focus and better followed the geological setting, indicating that our FWI strategy is compatible with traditional method and that, in order to get the best possible result, one would use our strategy subsequent to utilizing the traditional method.

We use full waveform inversion FWI and earthquake records to image crustal and upper mantle structures for several continents, including Europe, North America, Antarctic and Australia. Jointly interpreting these seismic attributes enables us to better infer physical and chemical origins of seismic heterogeneities, and improve our understanding on the properties and evolution of the crust, lithosphere, asthenosphere and transition zones.
The major goal of these studies is to provide accurate 3-D crustal velocity models to better constrain earthquake source parameters, including epicentral locations and moment tensor solutions, which enable us to better study induced seismicity in these regions. In addition, these crustal models can be utilized for strong ground motion simulations and earthquake hazard evaluation.
Subduction zones are also the main sites for natural hazards, such as earthquakes, volcanoes and tsunamis. Understanding how slabs sink from the surface to the deep Earth and how they interact with the ambient mantle is crucial for understanding the dynamic process of our planet.
