Crustal Faults. Shallow earthquakes in Cascadia, with depths no greater than about 35 km, are caused by the rupture of faults within the North American Plate. The sizes of earthquakes are related to how big their ruptures are, and the biggest crustal faults in our region could produce earthquakes with magnitudes as large as, perhaps, M7.5 ...E-mail to: < [email protected] >.

Seismic networks, used to detect and locate earthquakes, have been a mainstay of Cascade volcano monitoring networks since the 1970s. Seismicity at Cascade volcanoes is monitored in partnership between the Pacific Northwest Seismic Network (PNSN) and the CVO, as well as UNAVCO (through the Plate …EQ Waves. Earthquakes shake the ground because fault rupture releases vibrations that radiate in the form of seismic energy. These earthquake waves, also called body waves, come in two distinct forms: Primary or "P" waves and Secondary or "S" waves. When body waves reach the free surface of the earth some of their energy is converted into ... They are widespread, result in $1-2 billion in damages, and cause more than 25 fatalities each year. Landslides are frequently triggered by strong ground motions. They are an important secondary earthquake hazard. The term landslide includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows. Pacific Northwest Seismic Network ...

Sep 14, 2023 · In the Pacific Northwest, one hazard that everyone should prepare for is earthquakes. Oregon and Washington face significant risk of experiencing an earthquake along the Cascadia Subduction Zone, a 600-mile-long fault off the coast of the Pacific Northwest. Subduction zone faults can produce the largest earthquakes on Earth, and the Cascadia ... Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.If you have a negative rewards balance on your credit card, you may have some questions. For example, how did this happen?

The greatest volcanic hazards in the Pacific Northwest are: pyroclastic density currents, ash fall and lahars. Lava flows usually do not have great impact in our region because our Cascade volcanoes tend to erupt more viscous (thick, sticky) types of lava, which don't travel very far.
