Document Summary
What happened during the 1964 good friday earthquake along the. Alaskan shore (copper river delta barriers) that caused the barriers to grow in size. Why are depositional features found along this collision. The largest earthquake ever recorded in the northern hemisphere, registered at 8. 6. It also created tsunamis that wiped out communities in several seaports (valdez and seward). Some land rose by as much as 9m (uplift; raised beaches and intertidal platforms). Some land sunk 2-3 m along the kenai. Depositional features are found here due to the presence of glaciers. Ex: gulf of mexico, northern slope of alaska, coasts along eastern africa. Backed by hilly or low lying regions. What tectonic landform protects the marginal sea coast. A section of the fault ruptured approximately 23 km southeast of upper lityua bay, producing an 8. 3 magnitude earthquake. Backed by wide, relatively flat coastal plains.
