The Denali fault system forms an arc, convex to the north, across southern Alaska. The ground along the fault … See our Privacy Policy and Third Party Partners to learn more about the use of data and your rights. Sites such as this one provided the data for designing the pipeline fault crossing. During each, the axis of maximum compressive strain was subhorizontal and about north—south. Thus, source data was imported or digitized in its native projection and reprojected to the database projection (for instance, NAD 27 UTM to GCS WGS 1984). We map the 385-kilometer (km) long surface trace of the right-lateral, strike-slip Denali Fault between the Totschunda-Denali Fault intersection in Alaska, United States and the village of Haines Junction, … Patterns of early Tertiary folding and reverse faulting indicate that the McKinley fault was active at that time and suggest that this fault developed shortly after strike-slip activity ceased on the Hines Creek fault. ... New findings of earthquake recurrence on the Denali Fault line in southwest Yukon are helping researchers get closer to pinpointing when the next big one … The new European data protection law requires us to inform you of the following before you use our website: We use cookies and other technologies to customize your experience, perform analytics and deliver personalized advertising on our sites, apps and newsletters and across the Internet based on your interests. The purpose of this map is to show the location of and evidence for recent movement on active fault traces within the Hayward Fault Zone, California. Major movements on the Hines Creek fault ceased by the Late Cretaceous, but local dip-slip movements continued into the Cenozoic. Active faults in the Alaska Range and adjacent areas include those of the Denali fault system, including the Totschunda fault and the McGinnis Glacier fault; inactive faults include the Hines Creek fault. A fault scarp is visible near Augustana Creek, Alaska. The Denali fault is an active intraplate dextral strike-slip fault. Thus the fault system may mark a reactivated suture zone between continental rocks to the north and a late Paleozoic island arc to the south, as suggested by Richter and Jones (1973). Over the centuries, earthquakes have hitched one part of the … This publication updates previous fault maps of Oregon as a contribution to the larger U.S. Geological Survey effort to produce digital maps of active faults in the Pacific Northwest region. By the time Lewis and Clark arrived on the West Coast in 1805, it had been 105 years since the Cascadia Subduction Zone last ruptured, sending a large portion of the Pacific Ocean roaring toward the coast. Denali Fault. The Hines Creek fault may preserve a record of the early history of the fault system. and Nelson, S.W., 1980. This pattern suggests a Paleozoic and Mesozoic setting dominated by plate convergence, despite the possible large pre-Late Cretaceous lateral movement on the Hines Creek fault. By clicking “I agree” below, you consent to the use by us and our third-party partners of cookies and data gathered from your use of our platforms. The main shock occurred about 80 km (50 miles) east of the Denali … The Hines Creek fault … Click individual fault and fold traces to view basic fault parameters: name, age, slip rate, slip sense, dip direction, mapping certainty, and mapped scale. In addition, both of the Denali Fault earthquakes occurred at a depth in the Earth’s crust of 5 … On Nov. 3, 2002, the pipeline withstood a magnitude 7.9 earthquake that was centered along the Denali Fault. Earthquakes have been recorded in this … and the fault database. Maximum Wet/Dry Zone is shown on this map. ... Mw 7.8 and Denali fault … Minor Potential Faults: 2 feet lateral, 2 feet vertical. Source map data was in a wide variety of projections common in Alaska. A Magnitude 7.5 earthquake has occurred about 57 miles southeast of Sand Point, Alaska. Oligocene — middle Miocene tectonic stability and late Miocene—Pliocene uplift of crustal blocks may reflect periods of quiescence and activity, on the McKinley fault. The Denali fault system forms an arc, convex to the north, across southern Alaska. This content is currently not available in your region. A trace of the Denali Fault runs up the north side of the Canwell Glacier. The November 3, 2002, M w 7.9 Denali Fault earthquake produced about 340 km of surface rupture along the Susitna Glacier Thrust Fault and the right-lateral, strike-slip Denali and Totschunda Faults.

You’d be mistaken. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Post-Late Cretaceous dextral offset on this fault is probably at least 30 km and possibly as great as 400 km. The images that existed in Map Of Carlton oregon are … The Cenozoic pattern of faulting and folding appears compatible with a plate tectonic model of (1) rapid northward movement of the Pacific plate relative to Alaska during the early Tertiary; (2) slow northwestward movement of the Pacific plate during the Oligicene and (3) rapid northwestward movement of the Pacific plate from the end of the Oligocene to the present. In the central Alaska Range, the system consists of a northern Hines Creek strand and a southern McKinley strand, up to 30 km apart. The Denali Fault cuts across Alaska in a line that on satellite photos looks like a canal dug through the Alaska Range. Figure 3: The figure to the left represents two dimensional cross sections of the Denali Fault System (Jadamec, Margarete A. et al 2013). This National Park includes part of a massive mountain range more than 600 miles long. Map Of Carlton oregon pictures in here are posted and uploaded by secretmuseum.net for your map of carlton oregon images collection. Tips/Special Features: The Denali Fault provides a natural travel corridor through the high peaks and valleys of the unit from Foggy Pass in the eastern side to Easy Pass at the western end.Large and … With the exception of the Denali fault… Strong contrasts between juxtaposed lower Paleozoic rocks appear to require large dextral strike-slip or a combination of dipslip and strike-slip displacements along this fault. On Sunday, November 3, 2002, at 3:12 p.m. (MST), a large (magnitude 7.9) earthquake occurred on the Denali fault … The upper reaches of the Nenana flow out of the Nenana Glacier and runs south then west into a wide glacial valley and the primary access for the upper Class II stretch is from the Denali Highway at mile 20.This is a geologically interesting area as the river runs into the trench of the Denali Fault Line… We rely on readers like you to uphold a free press. Anchorage is precariously perched 100 miles south of the Denali Fault. The few remaining Native Americans in the area spoke of the earth shaking and ocean rising to consume the land.
