New Madrid Fault Line:
The New Madrid Fault Line produced over 2,000 earthquakes in a 5 month period between 1811 and 1812. FEMA predicts a 25% probability of a 7.5 magnitude or larger earthquake being produced from the New Madrid Fault Line (which covers the connecting borders of Tennessee, Missouri, and Arkansas) by the year 2040. Due to the geology on the east coast this earthquake will cause damage in more than 20 states in the eastern United States. FEMA reports at least an estimated 86,000 casualties, including 3,500 fatalities; 715,000 damaged buildings; and 7.2 million people displaced, with 2 million of those seeking shelter, primarily due to the lack of utility services. Direct economic losses, according to the report, would be at least $300 billion.
Summerville Fault Line:
The Summerville Fault in South Carolina, which produced the largest recorded earthquake on the east coast in 1886. Mark Peterson, chief of the USGS National Seismic Hazard Mapping Project has stated, “Our nation’s population and exposure to large earthquakes has grown tremendously in recent years. The cost of inaction in planning for future earthquakes and other natural disasters can be very high.” Seismic maps, as of 2014, show that Charleston is at a high risk for a damaging earthquake in the next 50 years. South Carolina is one of 16 states that have had a magnitude 6 earthquake or greater. After the 2011 earthquake in Virginia that measured 5.6 in magnitude scientists and geologists have additional geological evidence to suggest that the East Coast is active in seismic activity and have urged business and homeowners to prepare for additional seismic activity. It is not just hurricanes that put buildings at risk on the East Coast!
Major hurricanes such as Katrina, Irene, and Sandy have produced over $150 billion in damages and taken nearly 2,000 lives in the United States since 2005. The time to prepare your buildings and properties for hurricanes is not hurricane season! The time to prepare for major weather events is now.
