Re: Another Hurricane dance quake? M4 puerto rico |
The way I understand hurricanes, the low pressure causes the water to stand higher-maybe about 1 m for a strong hurricane. That would mean that the pressure at the seafloor would not change at all. It is only when a hurricane encounters a coastline (or at least shallow water) that the wind causes the water to pile up on the right side of the storm track. It is only then that a load is applied. 1 bar is atmospheric pressure. 10 m of water is equal to 1 bar. A strong storm surge could have 5 m. If you add 1/2 bar of vertical stress, it brings normal faults closer to failure. It is normal faults generally in the Gulf of Mexico. So, it is plausible to me that there could be a weak effect. Unlike much of what is discussed here, there is a cause and effect. Someone feel free to check my numbers. Follow Ups: ● Re: Another Hurricane dance quake?
