2012 TSUNAMI AWARENESS WEEK

THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION...NOAA...AND THE NATIONAL TSUNAMI HAZARD MITIGATION PROGRAM HAS DESIGNATED MARCH 25TH THROUGH MARCH 31ST AS TSUNAMI AWARENESS WEEK.

ALTHOUGH EXTREMELY RARE EVENTS...EARTHQUAKES OCCURRING IN THE PUERTO RICAN TRENCH AREA...OR IN AREAS IN THE ATLANTIC OCCURRING ALONG THE EASTERN SEABOARD...PRODUCING UNDERSEA SLIDES...HAVE THE GREATEST POTENTIAL FOR PRODUCING A TSUNAMI ON THE EAST COAST.

NOAA OPERATES A TSUNAMI WARNING SYSTEM FOR THE EAST COAST OF THE UNITED STATES THROUGH THE TSUNAMI WARNING CENTER LOCATED IN PALMER ALASKA. THE WARNING CENTER OPERATED 24 HOURS A DAY AND 365 DAYS A YEAR...ISSUES WATCH...WARNING AND ADVISORY INFORMATION MESSAGES AS EARLY AS 5 MINUTES AFTER AN EARTHQUAKE.

UPON RECEIPT OF THESE TSUNAMI ALERT MESSAGES STATE AND LOCAL EMERGENCY MANAGEMENT OFFICIALS WILL DETERMINE THE APPROPRIATE RESPONSE INCLUDING WHETHER OR NOT TO EVACUATE PEOPLE FROM THE WARNED AREA.

TO DATE MANY COASTAL COMMUNITIES HAVE RECEIVED THE TSUNAMIREADY DESIGNATION. ONSLOW COUNTY AND CAMP LEJEUNE ARE INCLUDED IN THIS LIST.

TO ASSIST TSUNAMI PREPAREDNESS EFFORTS...ON WEDNESDAY...MARCH 28TH...A TSUNAMI EXERCISE...LANTEX 12...WILL TAKE PLACE ALONG THE ATLANTIC AND GULF COASTS OF THE UNITED STATES. THE WEST COAST ALASKA TSUNAMI WARNING CENTER WILL SEND A TEST TSUNAMI WARNING MESSAGE REPLICATING A TSUNAMI GENERATED BY AND EARTHQUAKE THAT TRIGGERS A SUBMARINE LANDSLIDE OR SLUMP OFF THE SOUTH CAROLINA COAST. THIS TEST WARNING MESSAGE WILL BE SENT OUT BY THE TSUNAMI WARNING CENTER AT 904 AM EDT ON WEDNESDAY MARCH 28TH. THE SLUMP REPLICATES A SIMILAR EVENT THAT OCCURRED OFF THE GRAND BANKS ON NOVEMBER 18TH...1929...WHICH CAUSED EXTENSIVE DAMAGE TO COASTAL NEWFOUNDLAND AND KILLED 28 PEOPLE. AN EVENT LIKE THIS WOULD BE CHARACTERIZED BY A SERIES OF FAST MOVING WAVES UP TO 6 TO 9 FEET THAT WILL RUN UP INTO THE DUNES. THE WAVES WILL CREATE DANGEROUS CURRENTS AS WELL...BUT WOULD PRIMARILY IMPACT THE BEACHES AND INLETS DIRECTLY.

IN CONJUNCTION WITH THE TEST WARNING FROM THE TSUNAMI WARNING CENTER THE NWS IN NEWPORT WILL ACTIVATE A TEST TONE ALERT OF NOAA WEATHER RADIO ALL HAZARDS VIA THE ROUTINE WEEKLY TEST AROUND 910 AM EDT FOR OUR COASTAL TRANSMITTERS IN EASTERN NORTH CAROLINA. THE REGULAR ROUTINE WEEKLY TEST SCRIPT WILL BE USES FOR INLAND TRANSMITTERS...ALSO AT 910 AM, AS A RESULT OF THE EXERCISE THE NWS AND ITS PARTNERS WILL BE ABLE TO TEST THE LINES OF COMMUNICATION FOR A TSUNAMI EVENT...WHICH IS CRITICAL DURING AN ACTUAL WARNING TO EFFECTIVELY EVACUATE THE BEACHES AND GET PEOPLE TO HIGHER GROUND.ALTHOUGH EAST COAST TSUNAMIS ARE RARE...THEY HAVE HAPPENED ALONG THE EAST COAST...AND A VARIETY OF SOURCES EXIST INCLUDING...METEOROLOGICALLY INDUCED... LIKE WHAT HAPPENED IN DAYTONA IN 1992...LANDSLIDES FROM LAS PALMAS IN THE CANARY ISLANDS...SUBMARINE LANDSLIDES...LIKE WHAT HAPPENED ON THE GRAND BANKS...AND THE CURRITUCK SLUMP...TECTONIC AND SEISMIC FAULTS ASSOCIATED WITH THE PUERTO RICAN TRENCH...AND THE AZORES GIBRALTAR FAULT...AND ASTEROID IMPACTS. A SUBMARINE SLIDE WHICH OCCURRED OFF CURRITUCK THOUSANDS OF YEARS AGO WAS DETERMINED TO PRODUCE AN 18 FOOT WAVE WHICH OVER TOPPED DUNES ON THE OUTER BANKS.
