"The US has granted the first new permit for deepwater oil drilling in the Gulf of Mexico since last year's spill at a BP-owned oil well there."
Well looks like we have a new labratory too watch, and syncronize watch's at drilling commencement ,,,5,,4,,3,,2,1, "start recording".
Well Robin what do you think?

I've looked at the seismos for Ark today and what I see is a standard aftershock pattern, no different than anywhere else in the world. I am still studying the area, and the jury is out on the FRACing issue, which some say is the cause. I need to see more historical seismographical info from the NMZ, where can I find stuff that dates back 15-20 years? Or can I...?edit on 28-2-2011 by odd1out because: (no reason given)
To date, circulation systems have only been created by drilling one wellbore, hydraulically fracturing the well (which induces microearthquakes), locating the microearthquakes and then drilling a second wellbore through the zone of seismicity. A technique for analyzing the pattern of seismicity to determine where fracture planes are located in the seismically active region has recently been developed. This allows us to distinguish portions of the seismically active volume which are most likely to contain significant flow paths. We applied this technique to seismic data collected during a massive hydraulic fracturing (MHF) treatment and found that the fracture planes determined by the seismic method are confirmed by borehole temperature and caliper logs which indicate where permeable fractures and/or zones of weakness intersect the wellbores.
As with any development of new technology, some aspects of the technology has been accepted by the general public, but some have not yet been accepted and await further clarification before such acceptance is possible. One of the issues associated with EGS is the role of microseismicity during the creation of the underground reservoir and the subsequent extraction of the energy.
The fundamental objective of the present research was to understand how fracture networks are created in hydraulic borehole injection experiments, and how they subsequently evolve. When high-pressure fluids are injected into boreholes in geothermal areas, they flow into hot rock at depth inducing thermal cracking and activating critically stressed pre-existing faults. This causes earthquake activity which, if monitored, can provide information on the locations of the cracks formed, their time-development and the type of cracking underway, e.g., whether shear movement on faults occurred or whether cracks opened up.
Finally, we examined the nonpollutant effects of land subsidence and induced seismicity. Land subsidence is possible around some facilities, but surface-related damage is not expected to be great. Induced seismic events that have occurred to date at geothermal resource areas have been nondestructive. It is not possible to predict accurately the risk of potentially destructive events, and more research is needed in this area.

We just had another small "jolt" here and my house is still vibrating.....I hope it's not a sign of things to come tonight.
It didn't seem very big but I could feel the jolt then the vibrations. We just had another one even smaller. Your right ...they have put me on edge. PS: I did feel it just slight rumbles here you might not notice if you wern't sitting still. What seems different to me is my house won't stop vibrating. My wife has a lamp shade with feathers on the bottom and I'm watching them slightly vibrate and I can feel it in the floor on and off.

Well there's been about a dozen ones to small to feel. Their still happening. The one you felt doesn't seem that big. I would't blame you for being on edge and more sensitive. I understand being on edge.
