Regional uplift and subsidence occurred mainly in two nearly parallel elongate zones, together about 600 miles long and as much as 250 miles wide, that lie along the continental margin. From the earthquake epicenter in northern Prince William Sound, the deformation extends eastward 190 miles almost to long 142° and southwestward slightly more than 400 miles to about long 155°. It extends across the two zones from the chain of active volcanoes in the Aleutian Range and Wrangell Mountains probably to the Aleutian Trench axis.\n\nUplift that averages 6 feet over broad areas occurred mainly along the coast of the Gulf of Alaska, on the adjacent Continental Shelf, and probably on the continental slope. This uplift attained a measured maximum on land of 38 feet in a northwest-trending narrow belt less than 10 miles wide that is exposed on Montague Island in southwestern Prince William Sound. Two earthquake faults exposed on Montague Island are subsidiary northwest-dipping reverse faults along which the northwest blocks were relatively displaced a maximum of 26 feet, and both blocks were upthrown relative to sea level. From Montague Island, the faults and related belt of maximum uplift may extend southwestward on the Continental Shelf to the vicinity of the Kodiak group of islands. To the north and northwest of the zone of uplift, subsidence forms a broad asymmetrical downwarp centered over the Kodiak-Kenai-Chugach Mountains that averages 2½ feet and attains a measured maximum of 7½ feet along the southwest coast of the Kenai Peninsula. Maximum indicated uplift in the Alaska and Aleutian Ranges to the north of the zone of subsidence was l½ feet. Retriangulation over roughly 25,000 square miles of the deformed region in and around Prince William Sound shows that vertical movements there were accompanied by horizontal distortion, involving systematic shifts of about 64 feet in a relative seaward direction. Comparable horizontal movements are presumed to have affected those parts of the major zones of uplift and subsidence for which retriangulation data are unavailable.\n\nRegional vertical deformation generated a train of destructive long-period seismic sea waves in the Gulf of Alaska as well as unique atmospheric and ionospheric disturbances that were recorded at points far distant from Alaska. Warping resulted in permanent tilt of larger lake basins and temporary reductions in discharge of some major rivers. Uplift and subsidence relative to sea level caused profound modifications in shoreline morphology with attendant catastrophic effects on the nearshore biota and costly damage to coasta1 installations. Systematic horizontal movements of the land relative to bodies of confined or semiconfined water may have caused unexplained short-period waves—some of which were highly destructive—observed during or immediately after the earthquake at certain coastal localities and in Kenai Lake. Porosity increases, probably related to horizontal displacements in the zone of subsidence, were reflected in lowered well-water levels and in losses of surface water.\n\nThe primary fault, or zone of faults, along which the earthquake occurred is not exposed at the surface on land. Focal-mechanism studies, when considered in conjunction with the pattern of deformation and seismicity, suggest that it was a complex thrust fault (megathrust) dipping at a gentle angle beneath the continental margin from the vicinity of the Aleutian Trench. Movement on the megathrust was accompanied by subsidiary reverse faulting, and perhaps wrench faulting, within the upper plate. Aftershock distribution suggests movement on a segment of the megathrust, some 550–600 miles long and 110–180 miles wide, that underlies most of the major zone of uplift and the seaward part of the major zone of subsidence.\n\nAccording to the postulated model, the observed and inferred tectonic displacements that accompanied the earthquake resulted primarily from (1) relative seaward displacement and uplift of the seaward part of the block by movement along the dipping megathrust and subsidiary faults that break through the upper plate to the surface, and (2) simultaneous elastic horizontal extension and vertical attenuation (subsidence) of the crustal slab behind the upper plate. Slight uplift inland from the major zones of deformation presumably was related to elastic strain changes resulting from the overthrusting; however, the data are insufficient to permit conclusions regarding its cause.\n\nThe belt of seismic activity and major zones of tectonic deformation associated with the 1964 earthquake, to a large extent, lie between and parallel to the Aleutian Volcanic Arc and the Aleutian Trench, and are probably genetically related to the arc. Geologic data indicate that the earthquake-related tectonic movements were but the most recent pulse in an episode of deformation that probably began in late Pleistocene time and has continued intermittently to the present. Evidence for progressive coastal submergence in the deformed region for several centuries preceding the earthquake, in combin1ation with transverse horizontal shortening indicated by the retriangulation data, suggests pre-earthquake strain directed at a gentle angle downward beneath the arc. The duration of strain accumulation in the epicentral region, as interpreted from the time interval during which the coastal submergence occurred, probably is 930–1,360 years.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Alaska earthquake, March 27, 1964: Regional effects (Professional Paper 543)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/pp543I","usgsCitation":"Plafker, G., 1969, Tectonics of the March 27, 1964, Alaska earthquake: U.S. Geological Survey Professional Paper 543, Report: viii, 74 p.; 2 Plates: 27.08 x 21.87 inches and 16.09 x 20.66 inches, https://doi.org/10.3133/pp543I.","productDescription":"Report: viii, 74 p.; 2 Plates: 27.08 x 21.87 inches and 16.09 x 20.66 inches","numberOfPages":"88","costCenters":[{"id":380,"text":"Menlo ParkCalif.

This difference cannot be explained by biotic and oceanographic factors or by postdepositional alteration of original isotopic compositions. Metabolic fractionation of oxygen isotopes by Inoceramus is strongly implied by the data and is not contradicted by what is known of the processes involved in the biologic deposition of shell carbonate. In addition, the oxygen isotope compositions of the inocerams and of some baculites are so light as to indicate temperatures greater than 30° C, which is too high for mollusks to tolerate. The unreasonable range of the indicated temperatures seems to be partly the result of metabolic fractionation of oxygen and partly the result of the Late Cretaceous sea in the western interior region having had a light oxygen isotope composition because of dilution with fresh water. The carbon isotope composition of the aragonite from Inoceramus is consistently heavier than that of the calcite in the same specimen by amounts ranging from 1 to 3 per mil. Metabolic fractionation of carbon isotopes within Inoceramus thus is indicated. The carbon isotope composition of the aragonite from baculites and other cephalopods is consistently lighter than that in either the aragonite or calcite in Inoceramus, indicating either that the cephalopods fractionated carbon isotopes from the dissolved carbonate in sea water differently than did inocerams or that the cephalopods utilized carbon of a different isotopic composition, probably from their food source, for their metabolic processes. While oxygen isotope data from the inocerams are not useful for paleotemperature interpretations, the oxygen isotope data from the baculites, if taken at face value, suggest either warmer temperatures for the western interior sea than around the periphery of Cretaceous North America, or water of oxygen isotope composition lighter than world oceans, or both. Data from British Columbia, southeastern Alaska, and West Greenland to the Gulf Coastal Plain do not indicate a well-developed latitudinal distribution of temperature in Late Cretaceous time. A general decline in temperatures during late Campanian and early Maestrichtian time is not evident. © 1969, The Geological Society of America, Inc.

Shortly before the 1963 AGU gravity symposium [Barnes, 1965], the emphasis shifted from local surveys to the preparation of a reconnaissance gravity map of the whole state with a 10-mgal contour interval on a scale of 1:2,500,000, which would be similar to the gravity map of the United States [Woollard and Joesting, 1964]. Data have now been obtained in approximately three-fourths of the state, but there are large variations in both station density and geologic usefulness of the coverage. The amount of coverage is primarily influenced by the distribution of water bodies because more than three-fourths of the stations have been obtained by riverboats, small skiffs, and floatplanes.

A section of pre-trench, deep oceanic sediments rests on the down-warped crust that forms the trench. Nearly horizontal undeformed strata that unconformably overlie this deep oceanic section partially fill the trench. The trench fill is thickest near present sediment sources. A Pliocene age for development of the eastern Aleutian Trench is estimated from the thickness of deep oceanic sediment that accumulated after the trench began to fill. The eastern Aleutian Trench thus appears younger than the central Aleutian Trench—a relation which helps to explain the distribution of sediment along the two trench segments.
Depression of the eastern Aleutian Trench diminished or virtually ended soon after the trench began to fill. The undeformed fill provides no evidence for a large thrust fault zone at the base of the continental slope. Nor is there any evidence that oceanic sediments have disappeared beneath the continents in late Tertiary time. These observations are difficult to reconcile with the simple model of a continental margin advanced in the hypothesis of plate tectonics.

First, the use of high-speed computers and an increasing variety of supplemental data now make possible the geologic interpretation of gravity anomalies so small that they would not have been noticed in surveys made ten years ago. The kind of gravity interpretation that identifies small reefs and local accumulations of petroleum [McCulloh, 1967] often requires local increases in station density and the assurance that the calibration of meters used in all parts of a survey are compatible. Second, temporal changes of gravity have already been measured in connection with earthquakes [Barnes, 1966], volcanic eruptions [Iida et al, 1952], and the movement of ice caps [Behrendt, 1967]; they are now being considered for several other types of geologic processes.
