Oceanic transform faults exhibit tidally modulated seismic tremor, revealing a dynamic fluid system. This process involves fault sealing and drainage, influencing seismic activity and hydrothermal healing.
Area of Science:
- Geophysics
- Tectonics
- Oceanography
Background:
- Oceanic transform faults are typically viewed as conservative, shear-dominated tectonic boundaries.
- Their proximity to magmatic systems suggests potential fluid involvement and complex processes.
Purpose of the Study:
- To investigate the presence and characteristics of seismic tremor at oceanic transform faults.
- To understand the influence of tidal forces and fluid dynamics on fault activity.
Main Methods:
- Analysis of seismic tremor data from the Gofar transform fault.
- Correlation of tremor amplitude with semidiurnal tides.
- Examination of in-situ compressional to shear wave velocity ratio (Vp/Vs) before and after earthquake swarms.
Main Results:
- Discovery of tidally modulated tremor at the Gofar transform fault.
- Tremor amplitude correlates with tides during low Vp/Vs periods, but this correlation diminishes after earthquake swarms with high Vp/Vs.
- A valve-like sealing and drainage process is proposed to explain the observed phenomena.
Conclusions:
- Oceanic transform faults are permeable and influenced by tidal forces.
- Fault activity oscillates between tremor and rupture, regulated by magmatic volatile supply and hydrothermal resealing.
