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
StaDon LocaDons
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
