Central North Carolina Seismic Survey

Earthquakes  on  the  East  Coast  

Figure 3.3

Figure 3.9

East  Coast  is  a  “Passive-­‐Aggressive”  con8nental  margin  

Goals  of  this  project  •  Install  seismometers  at  6  –  12  sites  in  the  Deep  River  Basin  area,  focusing  on  areas  most  likely  to  be  developed  for  natural  gas  

•  ConDnuously  record  ground  moDon  for  at  least  1  full  year    

•  Use  these  recordings  to  look  for  any  naturally  occurring  seismicity  in  the  area  

•  Develop  a  baseline  profile  of  seismic  acDvity  to  use  for  comparison  in  the  event  of  future  increases  in  seismic  acDvity  

•  If  we  find  more  naturally  occurring  seismicity  than  we  expect  (and  we  don’t  expect  much),  evaluate  any  potenDal  for  natural  hazards  from  exisDng  faults    

StaDon  LocaDons  Ideally  as  close  to  the  basin  (and  in  the  basin)  as  possible  

Ideally  well  distributed  around  the  perimeter  of  the  basin

Ideal  Seismic  StaDon  LocaDons  

•  Must  haves:  •  Sunlight  (staDons  powered  by  solar  panels)  •  Security  

•  Like  to  haves:  •  Distance  from  noise  sources  

•  Trees  •  Pumps  •  Traffic  •  Trains  •  Major  highways  •  High  populaDon  density  areas
