Research Direction

1.Rupture process determination of Big earthquakes

Determining the rupture process of big earthquakes is the fundamental of earthquake studies, which also plays an important role in disaster relieving operations. In modern days, this task requires integrated adoption of seismic, geodetic and geologic observations. Because different observations have respective sensitivity to spatial and temporal information of the rupture processes, joint inversion exploit the different information achieving high resolution and stable inversion results.

Besides joint inversion, different inversion methods, e.g. linear or non-linear approaches and source parameterization methods, e.g. finite fault model and multi-point source, provides constraints of rupture processes from different perspectives. Below is the rupture model of the 2016 Kumamoto earthquake obtained by joint inversion of strong motion and geodetic observations.

Imaging technique is another strategy to determine the rupture processes. Adopting beam-forming techniques in global seismic networks, we can image the spatial and temporal information of the rupture processes. However, complicated earth structure is another source producing coherent energy of source images. These “artificial sources” need to be discriminated from real earthquake sources when interpreting the source images. We determined localized water reverberation phases produced by ocean bottom geometry, which was mis-interpreted as secondary sources. In the following figure, we show the wave field snapshot near the ocean floor and how such waves could be beamformed as coherent radiators.

2. Small earthquake detection

Besides large earthquakes, the fault also release elastic energy through small events. These small event serve as indicators for the fault geometry and stress loading and releasing processes. Thus detection of these small events is an important strategy to learn the physical structure and behavior of fault systems. My group probe into this problem through seismic network design and detection algorithms.

After the 2017 Jiuzhaigou earthquake, the research group of Han Yue and Shiyong Zhou deployed 80 short period seismic stations near the source region to detect aftershock activities. This network is locally refined as 9 sub-arrays, each composed of 8-16 seismic stations. Signal enhancement algorithms are designed for this network for better detection of aftershocks.

My group also achieve small event detection through artificial intelligence (AI) algorithms. As a popular machine learning algorithm, deep learning is widely used in research areas, which has large amount of training data. In seismology, the most straight forward application of deep learning is in the phase identification studies. We adopted convolutional and recurrent neural networks (CNN and RNN) in the event detection and phase picking algorithms and use manually picked P and S phases to train the network. The trained neural network achieved detection accuracy of higher than 98%. The following diagram shows the flowchart of the CNN and RNN neural networks.

3. Physical processes of fault systems

Besides the abrupt stress releasing process, i.e. earthquakes, the fault also release stresses through slow processes, e.g. slow-sips and creeping. These slow slips reflects the stress loading and releasing of fault planes, which may also reflects nucleation processes before big earthquakes. Therefore, these transitional slow-slip processes may provide useful information for earthquake short term predictions. In the study of 2016 Kumamoto earthquake, our group found transitional slow-slip signals from local GPS data before the mainshock, which may be associated with the nucleation of the mainshock. The following figure shows the GPS timeseries and seismic activities before the 2016 Mw 7.0 Kumamoto earthquake.
