• Geomorphic Effects of the Earthquake of March 27, 1964 in the Martin-Bering Rivers Area, Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "The Alaska earthquake of March 27, 1964, caused widespread geomorphic changes in the Martin-Bering Rivers area-900 square miles of uninhabited mountains, alluvial flatlands, and marshes north of the Gulf of Alaska, and east of the Copper River. This area is at lat 60°30' N. and long 144°22' W., 32 miles east of Cordova, and approximately 130 miles east-southeast of the epicenter of the earthquake. The geomorphic effects observed were: (1) earthquake-induced ground fractures, (2) mudvent deposits, (3) 'earthquake-fountain' craters, ( 4) subsidence, (5) mudcones, (6) avalanches, (7) subaqueous landslides, (8) turbidity changes in ice-basined lakes on the Martin River glacier, (9) filling of ice-walled sinkholes, (10) gravel-coated snow cones, (11) lake ice fractures, and (12) uplift accompanied the earthquake. In addition to geomorphic effects, the earthquake affected the animal populations of the area. These include migratory fish, terrestrial mollusks, fur-bearing animals, and man. The Alaska earthquake clearly delineated areas of alluvial fill, snow and rock avalanche corridors, and deltas of the deeper lakes as unsuitable for future construction."

• Gravity Survey and Regional Geology of the Prince William Sound Epicentral Region, Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "Following the Alaska earthquake of March 27, 1964, the U.S. Geological Survey made an intensive investigation of the effects of the earthquake in the Prince William Sound region where the epicenter was located. Concurrent investigations included studies of the regional geology, changes of land level, faulting, and effects of waves on shorelines which were summarized by Plafker and Mayo (1965). At the same time, this gravity survey, mentioned briefly by Barnes and Allen (1965), was conducted in order to establish the regional geologic and tectonic setting of the earthquake. Geologic sections of this report were prepared by Plafker and Case, the gravity sections by Case, Barnes, and Robbins."

• Hydrologic Effects of the Earthquake of March 27, 1964, Outside Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "The Alaska earthquake of March 27, 1964, had widespread hydrologic effects throughout practically all of the United States. More than 1,450 water-level recorders, scattered throughout all the 50 States except Connecticut, Delaware, and Rhode Island, registered the earthquake. Half of the water-level records were obtained from ground-water observation wells and half at surface-water gaging stations. The earthquake is also known to have registered on water-level recorders on wells in Canada, England, Denmark, Belgium, Egypt, Israel, Libya, Philippine Islands, South-West Africa, South Africa, and Northern Territory of Australia. The Alaska earthquake is the first for which widespread surface-water effects are known. The effects were recorded at stations on flowing streams, rivers, reservoirs, lakes, and ponds. The 755 surface-water stations recording effects are spread through 38 States, but are most numerous in the south-central and southeastern States, especially in Florida and Louisiana. Most of the fluctuations recorded can be referred to more precisely as seismic seiches; however, a few stations recorded the quake as a minor change in stage. The largest recorded seiche outside Alaska was 1.83 feet on a reservoir in Michigan. The next largest was 1.45 feet on Lake Ouachita in Arkansas. The largest fluctuation in a well was 23 feet registered by a pressure recorder near Belle Fourche, S. Dak. Fluctuations of more than 10 feet were reported from wells in Alabama, Florida, Georgia, Illinois, Missouri, and Pennsylvania. A 3.40-foot fluctuation was recorded in a well in Puerto Rico. The Alaska earthquake was registered by about seven times as many water-level recorders as recorded the Hebgen Lake, Mont., earthquake of August 19, 1959."

• Effects of the March 1964 Earthquake on the Hydrology of South-Central Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "The earthquake of March 27, 1964, greatly affected the hydrology of Alaska and many other parts of the world. Its far-reaching effects were recorded as water-level fluctuations in gages operated on water wells and streams. The close-in effects were even more striking, however; sediment-laden ground water erupted at the surface, and even ice-covered lakes and streams responded by seiching. Lake and river ice was broken for distances of 450 miles from the epicenter by seismic shock and seiche action. The surging action temporarily dewatered some lakes. Fissuring of streambeds and lakeshores, in particular, caused a loss of water, and hydrologic recovery took weeks in some places. Landslides and snow avalanches temporarily blocked streams and diverted some permanently. The only stream or lake structures damaged were a tunnel intake and two earthen dams. The winter condition-low stages of water and the extensive ice cover on lakes and streams-at the time of the earthquake greatly reduced the damaging potential. Ground water was drastically affected mostly in unconsolidated aquifers for at least 160 miles from the epicenter. Within 100 miles of the epicenter, vast quantities of sediment-laden water were ejected in most of the flood plains of the glaciofluvial valleys. A shallow water table and confinement by frost seemed to be requirements for the ejections, which were commonly associated with cratering and subsidence of the unconsolidated material. Subsidence was also common near the disastrous submarine landslides, and was probably caused by loss of water pressure and by lateral spreading of sediments. Effects on ground water in bedrock were not determinable because of lack of data and accessibility, particularly within 50 miles of the epicenter. Deep aquifers in unconsolidated sediments, which in most areas are under high hydrostatic pressure, were also greatly affected. Post-earthquake water levels for a year were compared with long-term prequake levels to show permanent changes in an aquifer system. At Anchorage and in parts of the Kenai Peninsula, artesian-pressure levels dropped as much as 15 feet. These lower pressures were probably caused either by grain rearrangement which increased the porosity within the aquifer or by a displacement of material that allowed water to discharge more freely at the submarine terminus of the aquifer. Seismically induced pressure on ground water was instrumental in causing most of the disastrous slides. Water quality was not changed except for temporary increases in turbidity in wells and streams. The sediment load in streams during the April spring runoff appeared to be greatly increased over previous years."

• Effects of the March 1964 Alaska Earthquake on the Hydrology of the Anchorage Area

  Show summary     Open resource [pdf]     (open full abstract)

  "The Anchorage hydrologic system was greatly affected by the seismic shock. Immediate but temporary effects included increased stream discharge, seiche action on lakes, and fluctuations in ground-water levels. Generally, ground-water levels were residually lowered after the initial period of fluctuation. This lowering is attributed either to changes in the discharge zones offshore or to a change in the permeability of the aquifers by seismically induced strain. Water supplies were disrupted temporarily by snowslides on streams and by sanding or turbidity in wells. Saltwater encroachment to wells on Fire Island seems to have increased. The approximate 3.7-foot lowering of land level and the diminished artesian head may permit further salt-water encroachment. Increased pore pressure in the Pleistocene Bootlegger Cove Clay led to liquefaction in silt and sand lenses that contributed to the disastrous bluff landslides. Measurements after the earthquake indicate that most pore pressures are declining, whereas some remain high or are increasing. Subsidence in the area was caused principally by tectonic readjustment, but differential compaction within the Bootlegger Cove Clay contributed to subsidences estimated to be as much as 0.6 foot beneath Anchorage."

• 1961 Eruption of Kilauea Volcano Hawaii

  Show summary     Open resource [pdf]     (open full abstract)

  "The 1961 eruption or Kilauea Volcano, through the period February 24 to September 25, 1961, consisted of three summit eruptive phases followed by a flank eruptive phase. Tumescence of the Kilauea summit area, which began in the summer of 1960, continued virtually unchanged throughout and after the three periods of summit eruption. Rapid detumescence accompanied the flank eruption. Seismic activity during tumescence was moderate and persistent, but it gave no particular forewarning of imminent eruption. However, a swarm of relatively large earthquakes and strong harmonic tremor preceded the flank eruptive phase by about 16 hours."

• Effects of the Earthquake of March 27, 1964 at Whittier, Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "Whittier, Alaska, lying at the western end of Passage Canal, is an ocean terminal of The Alaska Railroad. The earthquake that shook south-central Alaska at 5:36 p.m. (Alaska Standard Time) on March 27, 1964, took the lives of 13 persons and caused more than $5 million worth of damage to Government and private property at Whittier. Seismic motion lasted only 2[and a half]-3 minutes, but when it stopped the Whittier waterfront was in shambles land the port facilities were inoperable. Damage was caused by (1) a 5.3-foot subsidence of the landmass, sufficient to put some of the developed land under water during high tides, (2) seismic shock, (3) fracturing of fill and unconsolidated sediments, (4) compaction of fill and unconsolidated deposits, (5) submarine landslides which generated waves that destroyed part of The Alaska Railroad roadbed and other property, (6) at least two, but probably three, waves generated by landslides, which completely wrecked the buildings of two lumber companies, the stub pier, the small-boat harbor, the car-barge slip dock, and several homes, and (7) fire that destroyed the fuel-storage tanks at the Whittier waterfront. Many buildings and other facilities were totally wrecked, others were damaged to lesser degrees. For example, the 14-story reinforced-concrete Hodge Building, which rests upon at least 44 feet of sandy gravel, was moderately damaged by seismic shock, but the six-story reinforced-concrete Buckner Building, which rests upon bedrock, was only slightly damaged."

• Effects of the Earthquake of March 27, 1964 at Anchorage, Alaska

  Show summary     Open resource [pdf]     (open full abstract)

  "Anchorage, Alaska's largest city, is about 80 miles west-northwest of the epicenter of the March 27 earthquake. Because of its size, Anchorage bore the brunt of property damage from the quake; it sustained greater losses than all the rest of Alaska combined. Damage was caused by direct seismic vibration, by ground cracks, and by landslides. Direct seismic vibration affected chiefly multistory buildings and buildings having large floor areas, probably because of the long period and large amplitude of the seismic waves reaching Anchorage. Most small buildings were spared. Ground cracks caused capricious damage throughout the Anchorage Lowland. Cracking was most prevalent near the heads or within landslides but was also widespread elsewhere. Landslides themselves caused the most devastating damage."

  "In order to provide a better understanding of how the surface transportation system is both affected and utilized in an emergency situation, the U.S. Department of Transportation Intelligent Transportation Systems (ITS) Joint Program Office and the Federal Highway Administration (FHWA) Office of Operations commissioned a series of six case studies examining the effects of catastrophic events on transportation system management and operations: 1. Blackout, New York-New Jersey-Connecticut Metropolitan Area, August 14, 2003 2. Blackout, Great Lakes Region, August 14, 2003 3. Terrorist attack, New York City, September 11, 2001 4. Terrorist attack, Washington, D.C., September 11, 2001 5. Rail tunnel fire, Baltimore, Maryland, July 18, 2001 6. Earthquake, Northridge, California, January 18, 1994 Each of the events resulted in substantial, immediate, and adverse impacts on the transportation system, and each has had a varying degree of influence on the longer-term operation of transportation facilities and services in its respective region. This comparative analysis summarizes the surface transportation activities associated with these catastrophic events and the lessons learned from each. The case studies have provided material for a series of Transportation Response and Recovery Workshops developed by the FHWA and held in major metropolitan areas around the country."

• Civil Defense for National Security

  Show summary     Open resource [pdf]     (open full abstract)

  "In accordance with the terms of your Directive creating the Office of Civil Defense Planning, dated March 27, 1948, I submit to you herewith a National, Regional, State and Community plan for civil defense for national security. It is the purpose of this report to recommend for adoption a permanent peacetime system of civil defense which will round out our defense structure and which, in the event of an emergency, can be quickly and easily expanded to meet the exigencies of a given situation. Such an organization can also be of great value in support of existing agencies in meeting devastating peacetime disasters such as fires, floods, earthquakes, tornadoes, hurricanes, explosions and similar catastrophes. In the event of a future war, which might come to our shores, all of the people, all of the facilities and all of the skills and energies of the nation must be utilized to the fullest extent. To successfully carry out this program will require the cooperation of every man, woman and child in this nation. It is on such principles that civil defense must be erected and it must be with such a requirement that its organization be perfected. We hope that the Civil Defense Organization will never need to operate for war, but we dare not gamble on that hope. We who have studied the problem feel a great need for prompt action in establishing such an organization. To be without it leaves us in a most vulnerable position."
