Question: In which month of 1964 was Middleton Island raised 12 ft above sea level?

<P0-S0> Tidal flooding, also known as sunny day flooding or nuisance flooding, is the temporary inundation of low-lying areas, especially streets, during exceptionally high tide events, such as at full and new moons. <P0-S1>  The highest tides of the year may be known as the king tide, with the month varying by location. <P0-S2>  In Florida, controversy was created when state-level government mandated that the term "nuisance flooding" and other terms be used in place of terms such as sea level rise, climate change and global warming, prompting allegations of climate change denial, specifically against Governor Rick Scott. <P0-S3>  This amid Florida, specifically South Florida and the Miami metropolitan area being one of the most at risk areas in the world for the potential effects of sea level rise, and where the frequency and severity of tidal flooding events increased in the 21st century. <P0-S4>  The issue is more bipartisan in South Florida, particularly in places like Miami Beach, where a several hundred million dollar project is underway to install more than 50 pumps and physically raise roads to combat the flooding, mainly along the west side of South Beach, formerly a mangrove wetland where the average elevation is less than one meter (3.3 feet). <P0-S5>  In the Miami area, where the vast majority of the land is below 10 ft , even a one-foot increase over the average high tide can cause widespread flooding. <P0-S6>  The 2015 and 2016 king tide event levels reached about 4 ft MLLW, 3 ft above mean sea level, or about 2 ft NAVD88, and nearly the same above MHHW. <P0-S7>  While the tide range is very small in Miami, averaging about 2 ft , with the greatest range being less than 2 m , the area is very acute to minute differences down to single inches due to the vast area at low elevation. <P0-S8>  NOAA tide gauge data for most stations shows current water level graphs relative to a fixed datum, as well as mean sea level trends for some stations. <P0-S9>  During the king tides, the local Miami area tide gauge at Virginia Key shows levels running at times 1 ft or more over datum. <SEP> <P1-S0> The 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, occurred at 5:36 PM AST on Good Friday, March 27. <P1-S1>  Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths. <SEP> <P2-S0> The base level of a river or stream is the lowest point to which it can flow, often referred to as the 'mouth of the river'. <P2-S1>  For large rivers, sea level is usually the base level, but a large river or lake is likewise the base level for tributary streams. <P2-S2>  All rivers and streams erode toward sea level, which is also known as the "ultimate base level." <P2-S3>  A rather rare exception can be seen in the Jordan River, for which the base level is the Dead Sea, 417 m below modern sea level. <P2-S4>  If a river is dammed, a new base level (the level of the reservoir) replaces the ultimate base level. <P2-S5>  As a result, the stream’s base level is raised. <P2-S6>  Consequently, this reduces the stream’s velocity, leads to deposition, and a reduction of the gradient upstream from the reservoir. <SEP> <P3-S0> Middleton Island is a small, uninhabited island in the U.S. state of Alaska, located in the Pacific Ocean approximately 80 mi southwest of Cordova. <P3-S1>  The island was briefly home to Middleton Island Air Force Station, an early warning radar station, from 1958 until the station's closure in 1963. <P3-S2>  During the 1964 Alaska earthquake the island was raised an additional 12 ft above sea level. <P3-S3>  The island now hosts the unattended Middleton Island Airport and a NEXRAD weather radar.
