Subject: RE: BS: Hurricanes & Earthquakes - related? From: Nigel Parsons Date: 21 Sep 17 - 06:39 AM Although no link has been found yet, we are seeing new extremes of weather, and are better placed to link cause and effect than we have previously been. I wouldn't rule out there being a causal link. |

Subject: RE: BS: Hurricanes & Earthquakes - related? From: Teribus Date: 21 Sep 17 - 06:20 AM I thought that the tidal surge you get from large tropical storms are caused by high but very localised pressure difference and wind speed pushing, acting on, the water that was already there, I don't think that any additional water has been pulled in from anywhere. Seen and experienced the effects of two hurricanes close up while at sea on an RN ship acting as "Hurricane Guard Ship" out in the West Indies. This Hurricane season seems to be a very active one with fierce Hurricanes sweeping in one after another which makes relief and emergency work extremely difficult. |

The same as filling large reservoirs or injection(eg fracking) can create microseismic events, as also can pumping from oil and gas reservoirs. http://www.nature.com/nature/journal/v459/n7248/full/nature08042.html?foxtrotcallback=true https://sites.ualberta.ca/~vanderba/papers/DKV09.pdf |

Subject: BS: Hurricanes & Earthquakes - related? From: Mr Red Date: 21 Sep 17 - 06:00 AM Yes yes, Mexico City is prone to earthquakes. Hence this question. But I was wondering, with all that storm surge pulling water into the gulf adding weight to the Earth's crust locally then releasing it, it must be giving the crust a kick (in geological timescales). And several kicks this year. Look at how glass behaves - it is a super-cooled liquid after all (no latent heat of fusion). If it has a crack/scratch and you tap it - it splits/lengthens. cf the crust. FWIW The Gulf of Mexico has a mean sea level 6ft above the Pacific side of the isthmus. Due to tidal drag. |
