FOREWORD 
In the lab afternoon of  Friday, March 27, 1964, one of 
the most violent  earthquakes of  tall  time mked southern 
Alaska.  Suddenly 114 people were killed, thousands were 
left homeless, more than 50,000  square miles of  the State 
was tilted to new altitudes, and the resulting property dam- 
age disrupted the State's economy. 
The response to alleviate the effects of  the disaster was 
immediate.  The military forces in Alaska  rushed  to the 
aid of the civilian community, providing emergency com- 
munications,  food, water,  and housing.  Within 24 hours 
bhe U.S. Geological Survey had a team of  three geologists 
in Alaska to begin a reconnaissance survey, and they were 
but the vanguard of many who arrived to conduct scientific 
and engineering investigations and to advise on the recon- 
struction effort.  The day after the earthquake the President 
declared  Alaska  to be a  major disaster area and  a  wide 
range of  relief hnd reconstruction work began, much 'of it 
sponsored by the Office of Emergency Planning.  The Corps 
of  Engineers was given responsibility  for large parts of 
the reconstruction effort.  Within a week the President by 
Executive  Order  established  the  Federal  Reconstruction 
and  Development  Planning  Commission  for  Alaska  to 
coordin'ate the efforts of many Federal agencies; task forces 
and field teams moved into action. 
At the time of  the disaster it was  difficult to envision 
any good proceeding from it, but the unprecedented cooper- 
ative  efforts  of  many  agencies  and  institutions,  federal, 
state, land private, and many individuals have en'abled the 
State to recover in large measure and even to move for- 
ward.  This volume contains the story of  the earthquake 
and the succeeding field investigations  and reconstruction 
efforts in which  the Geological Survey is proud  to have 
taken part.
