The Great Central U.S ShakeOut “Drop, Cover, and Hold On” drill scheduled for 10:15 a.m. Feb. 7
The Great Central U.S ShakeOut Overview
Are You Ready to ShakeOut?
200 years ago, a series of major earthquakes struck the
Mississippi River Valley along the New Madrid Seismic Zone.
Recent events remind us that damaging earthquakes can
happen at any time. With more than 40 million people living
and working in the region today, a major earthquake would
cause widespread damage and disruption.
What we do now, before a big earthquake, will determine what our lives will be like afterwards.
With earthquakes an inevitable part of our future, we must act quickly to ensure that disasters do
not become catastrophes.
The Great Central U.S. ShakeOut in February 2012 will involve more than 1 million people through
a broad-based outreach program, partnership with the media, and public advocacy by hundreds of
partners. This event is being organized by the Central United States Earthquake Consortium and
the states of Alabama, Arkansas, Kentucky, Illinois, Indiana, Mississippi, Missouri, Oklahoma, and
Tennessee. The ShakeOut will be centered around a simultaneous
Drop, Cover, and Hold On drillthat will be held at 10:15 AM CDT on February 7, 2012.
Drop, Cover, and Hold On is the easy‐to-remember and recommended
personal protective action to take in the event of an earthquake.
February 7th is also the 200th anniversary of the last of the 1811‐
12 earthquakes that destroyed the town of New Madrid, Missouri and
created Reelfoot Lake in northwest Tennessee.
A key aspect of the ShakeOut is the integration of earthquake
research and the lessons learned from social science research
about why people get prepared for disasters. The result is a “teachable moment” on par
with having an actual earthquake (often followed by increased interest in getting ready for earthquakes).
The ShakeOut creates the sense of urgency that is needed for people,
organizations, and communities to get prepared, to practice what to do to be
safe, and to learn what plans need to be improved.
The ShakeOut inspires communities to work
together towards disaster preparedness, and
sets aside specific time for them to take proactive
action to become better prepared.
The 2012 ShakeOut drill will follow on the success
of the 2011 drill, where more than 3 million
people participated in the largest preparedness event
in central U.S. history. Interested participants are encouraged
to go to www.shakeout.org/centralus
and pledge their family, school,
business, or organization’s participation in the drill.
Registered participants will receive
information on how to plan their drill and
how to create a dialogue with others
about earthquake preparedness.

NWS Service Assessment Report from the April 27, 2011 tornado outbreak.
Following is the Executive Summary, but for the report can be found online at http://www.nws.noaa.gov/os/assessments/pdfs/historic_tornadoes.pdf
ooooooooooooooooooooo
On April 27, 2011, a series of devastating tornadoes struck the southeastern United States.
This tornado event was the third deadliest in the country since systematic tornado record keeping
began in 1950. With 316 fatalities (31 in Mississippi, 234 in Alabama, 32 in Tennessee, 15 in
Georgia, and 4 in Virginia), it follows only the 1974 Super Tornado Outbreak (368 deaths) and
the 1965 Palm Sunday Tornado Outbreak (337 deaths). Damages from this tornado episode
resulted in over $4.2 billion in property damage and more than 2,400 injuries.
The National Weather Service (NWS) formed a Service Assessment Team to evaluate its
performance. To strengthen NWS relationships with other federal agencies involved with
disaster work, for the first time this assessment had a co-leader from the Federal Emergency
Management Agency. The team interviewed staff and reviewed products from the Storm
Prediction Center (SPC), Weather Forecast Offices at Memphis and Morristown, TN, Jackson,
MS, Huntsville and Birmingham, AL, and Peachtree City, GA. The team gathered feedback
from partners and users of NWS products including media outlets, Emergency Managers at the
state and local level, first responders, and the public. One
of the team’s tasks was to assess
societal impacts of this event.
This tornado outbreak was anticipated and forecast days in advance. The SPC began
focusing on the affected area in its convective outlook products 5 days prior to the event. It
continued emphasizing, refining, and enhancing the threat leading up to the event, ultimately
issuing a high risk convective outlook on the morning of April 27 for a large portion of the
impacted area.
The Weather Forecast Offices (WFO) in the affected area prepared for severe weather
operations and indicated the risk of severe weather and tornadoes as much as 5 days in advance.
Hazardous Weather Outlooks, Web images, pre-recorded multimedia briefings, and webinars
discussed the potential impacts. Emergency Managers and media staff interviewed indicated
they were well prepared for the severe weather that occurred.
All tornado fatalities occurred within the boundaries of tornado watches and were preceded
by tornado warnings. There were several tornado watches issued in the afternoon before severe
weather began. The lead time, the time from the initial three watch issuances to the first
tornadoes in those watches, averaged 2.4 hours. Watch lead times to the first significant tornado
in each area ranged from 3-6 hours. The mean lead time for tornado warnings in the assessment
area was 22.1 minutes. The probability of detection was 89 percent and the false alarm ratio was
49 percent.
Despite the excellent performance of the SPC and WFO staff, the tornadoes resulted in a
substantial death toll. Contributing factors to the high number of casualties included:
A large number of rare, long-track, violent tornadoes
Tornado tracks intersecting densely populated areas
Damage to warning dissemination sources
Individuals in the affected areas who did not respond to warnings until confirmed by
more than one communication source
People in the paths of the storms who waited for visual confirmation before taking
protective action
The rapid pace of the storms, which moved at 45-70 mph, giving people who waited for
secondary confirmation a smaller window of time in which to take shelter
Residences that did not have adequate storm shelters
So many deaths resulting from an event in which the NWS performed well suggested that
societal and sociological factors regarding warning response played a role. To address this, the
NWS included four social scientists on the assessment team: one each from NWS, the Centers
for Disease Control and Prevention, the University of Northern Alabama, and the University of
Delaware. This team had the largest number of social scientists ever included on a Service
Assessment, reflecting the depth of sociological information in this report. Appendix C
describes procedures for data collection and assessment methodologies employed by the social
scientists.
The team determined that WFOs and state and local emergency management had developed
excellent relationships. The team also found opportunities for improved use of NWS products
and services in planning and training for natural hazards.
There were several success stories during this event. The relationships fostered by WFOs
with their media and emergency management partners allowed for efficient exchange of
information before and during the tornadoes. WFOs in impacted areas used webinars,
multimedia presentations, Web graphics, and social media services to disseminate information to
key partners and the public. Emergency management and media partners unanimously praised
these decision support services. Members of the public who heeded the warnings and took cover
in underground storm shelters survived the most violent tornadoes.
The team submitted 24 recommendations to address NWS performance, safety, and outreach
programs. In addition, the team identified 14 best practices. Appendix B offers definitions of
facts, findings, recommendations, and best practices followed by a complete listing of findings,
recommendations, and best practices found in the main body of the report. Appendices D and E
contain summaries of the tornado events that impacted the St. Louis metropolitan area and
North Carolina/South Carolina/Virginia, respectively.
