Get Avoiding Earthquake Surprises In The Pacific Northwest Answer Key

“Earthquakes can't be prevented. However, people can take measures to minimize the damage they cause. In some cases, communities can strengthen existing dams, bridges, water systems, schools, hospitals, and lifelines (electrical, gas, and water lines). They can also design and build earthquake-resistant structures.”

Three types of earthquakes occur in the Pacific Northwest: subduction, deep, and shallow (or surface). (Also described in Panel Text, pg. 3.) Interaction between the Juan de Fuca oceanic plate and the North America continental plate drives these faults.

The Pacific Northwest is host to three kinds of tectonic earthquakes : Magnitude nine Cascadia megathrust quakes. Magnitude 6.5 to seven deep earthquakes , and. Shallow crustal-fault earthquakes with magnitudes up to 7.5.

Cascadia is a region in the Pacific Northwest. It includes southern British Columbia, Washington, Oregon, and northern California. This region is at risk of being hit by earthquakes.

The Pacific Northwest sits squarely within the Ring of Fire. Off its coast, an oceanic plate is slipping beneath a continental one. Inland, the Cascade volcanoes mark the line where, far below, the Juan de Fuca plate is heating up and melting everything above it.

This revision of the code was an important first step toward meeting the great-earthquake threat in the Pacific Northwest. In the areas upgraded to the second highest level, new buildings are designed to withstand earthquakes fifty percent stronger than under the old code.
