Sediment structure at the equatorial mid-atlantic ridge constrained by seafloor admittance using data from the PI-LAB experiment
Well-constrained marine sediment characteristics (sediment thickness and shear wave velocity) are important not only for the study of climate over...

A statistical analysis of volcano-tectonic earthquake swarms in the off Nicobar region of the Andaman Sea
The present research work is primarily carried out to select the suitable and better variants or functions of ETAS models to describe the energetic...

Full waveform inversion of combined towed streamer and limited OBS seismic data: a theoretical study
In marine seismic oil exploration, full waveform inversion (FWI) of towed-streamer data is used to reconstruct velocity models. However, the FWI of...

Correlation of porosity variations and rheological transitions on the southern Cascadia megathrust
The unknown onshore extent of megathrust earthquake rupture in the Cascadia subduction zone represents a key uncertainty in earthquake hazard for the...

Tsunami hazard assessment in the South China Sea: A review of recent progress and research gaps
The South China Sea region is potentially threatened by tsunami hazards originated from multiple sources: the Manila subduction zone in the east, the...

Sensitivity analysis of P-waves and S-waves to gas hydrate in the Shenhu area using OBS
Compared to towed streamers, ocean-bottom seismometers (OBS) obtain both S-wave data and richer wavefield information. In this paper, the induced...

Stress transition from horizontal to vertical forces during subduction initiation
Subduction zones are fundamental to plate tectonics, yet how they initiate remains enigmatic. Geodynamic models suggest that if horizontal forces...

Subslab heterogeneity and giant megathrust earthquakes
The nucleation and rupture processes of giant megathrust earthquakes ( M ≥ 9.0) in subduction zones are still controversial. Most previous studies...

Inversion of ocean-bottom seismometer (OBS) waveforms for oceanic crust structure: a synthetic study
The waveform inversion method is applied—using synthetic ocean-bottom seismometer (OBS) data—to study oceanic crust structure. A niching genetic...

General Discussion
In the previous chapters, we developed a new method for conducting receiver function (RF) analysis using ocean-bottom seismometer (OBS) data and...

Conclusion
In this thesis, we developed a method to calculate receiver functions (RFs) from ocean-bottom seismometer (OBS) data, in which water reverberations...
