  6. PNW Plate tectonics Consists of all three types of plate interaction. These interactions puts the PNW at risk for volcanic eruptions, earthquakes, and Tsunamis.

  11. Overview of Hazards in the PNW PNW geological hazards will happen, so the focus is on how to lessen their impact, not prevent them. Though warning systems and evacuation plans are put in place, only volcanic prediction models have proven reliable. USGS. (2009) Dynamic Earth. Retrieved January 21, 2010 from http://pubs.usgs.gov/gip/dynamic/dynamic.pdf

  12. Emergency Kits America Red Cross (2009) recommends a basic kit should include the following: • A 3 day supply of water and food. • Flashlight • Battery-powered or hand cranked radio and/or cell phone with charger • First Aid Kit • Whistle • Multipurpose tool • Dust Mask, Duct Tape, Garbage Bags and Toilet Paper American Red Cross. (2007) Build a kit. Retrieved January 23, 2010 from http://www.redcross.org/preparedness/educatorsmodule/EDU_Be_Disaster_Safe/6-8%20BDS%20LP%208%20build%20a%20kit.pdf Katz, L.

  13. Additional Emergency Kits Supplies • Matches • Fire extinguisher. • Needles and thread. • Paper plates, plastic cups and utensils. • Chlorine bleach and other disinfectant cleaners. • Writing supplies and contact numbers. • Copies of important documents. Cash or traveler's checks. • Blankets, bedding, sleeping bags. • Comfortable clothes and shoes. • Supplies for babies, children, elderly, and pets. American Red Cross. (2007) Build a kit.

  14. Preparing for a disaster. • Evaluate the surrounding environment. • Know evacuation routes and meet up locations. • Have emergency kits readily available. • If ask to evacuate…evacuate. American Red Cross. (2009) Earthquake Safety Checklist. http://www.redcross.org/www-files/Documents/pdf/Preparedness/checklists/Earthquake.pdf USGS. (2009) Dynamic Earth. Retrieved January 21, 2010 from http://pubs.usgs.gov/gip/dynamic/dynamic.pdf

  15. What to do in a Earthquake? If you are inside when the shaking starts … Drop, Cover and Hold! Figure 10. Drop, Cover and Hold. American Red Cross. (2009) Earthquake Safety Checklist. http://www.redcross.org/www-files/Documents/pdf/Preparedness/checklists/Earthquake.pdf University of Washington. () UW Emergency Management: Drop Cover and Hold Poster. Retrieved February 1, 2010 from http://www.washington.edu/emergency/prepare/drop_cover_hold

  16. What to do in a Earthquake? If you are outside when shaking starts…Find a clear, open spot and drop to the ground. If you are driving, if safety permits pullover, and stay in your vehicle! Figure 11. Photographs of some damage caused by the 1994 Northridge earthquake. American Red Cross.

Retrieved February 3, 2010 from http://www.data.scec.org/chrono_index/northshow.html

  17. What to do after an Earthquake After an earthquake, the disaster may continue. Expect and prepare for potential aftershocks, landslides or even a tsunami. American Red Cross. (2009) Earthquake Safety Checklist. http://www.redcross.org/www-files/Documents/pdf/Preparedness/checklists/Earthquake.pdf • Each time you feel an aftershock, respond and take appropriate actions. • If you are okay, help others, if not seek first aid. • Cover exposed skin, to avoid injury if available. • Listen to a portable, battery-operated or hand-crank radio for updated emergency information and further instructions. • Help people who require special assistance, such as infants, children and the elderly or disabled.

  18. What to do after an Earthquake • Assess for damage. • Check for phone service, and make brief calls to report life-threatening emergencies. • Extinguish small fires if able. • Clean up potential spilled hazards immediately if you are able. • Note and stay clear of hazards such as fallen power lines, broken gas lines, or damaged areas. American Red Cross. (2009) Earthquake Safety Checklist. http://www.redcross.org/www-files/Documents/pdf/Preparedness/checklists/Earthquake.pdf

  19. What to do after an Earthquake • Keep animals under your direct control. • Stay out of damaged buildings. • If you were away from home, return only when authorities say it is safe to do so. • Use extreme caution and examine walls, floors, doors, staircases and windows to check for damage. • Be careful when driving after an earthquake and anticipate traffic light outages” American Red Cross. (2009) Earthquake Safety Checklist. http://www.redcross.org/www-files/Documents/pdf/Preparedness/checklists/Earthquake.pdf

  20. Conclusion Plate Tectonics occur worldwide in three distinct patterns. These collisions result in potential hazards ranging from earthquakes to tsunamis to volcanoes. It is difficult to know when, but we know they will happen! So it is best to be prepared!!!!
