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

Overview of Hazards in the 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.

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.

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.

What to do after an Earthquake After an earthquake, the disaster may continue. Expect and prepare for potential aftershocks, landslides or even a tsunami. 1. Each time you feel an aftershock, respond and take appropriate actions. 2. If you are okay, help others, if not seek first aid. 3. Cover exposed skin, to avoid injury if available. 4. Listen to a portable, battery-operated or handcrank radio for updated emergency information and further instructions. 5. Help people who require special assistance, such as infants, children and the elderly or disabled. American Red Cross. (2009) Earthquake Safety Checklist. http: //www. redcross. org/wwwfiles/Documents/pdf/Preparedness/checklists/Earthquake. pdf
What to do after an Earthquake 6. Assess for damage. 7. Check for phone service, and make brief calls to report life-threatening emergencies. 8. Extinguish small fires if able. 9. Clean up potential spilled hazards immediately if you are able. 10. 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/wwwfiles/Documents/pdf/Preparedness/checklists/Earthquake. pdf
What to do after an Earthquake 11. Keep animals under your direct control. 12. Stay out of damaged buildings. 13. If you were away from home, return only when authorities say it is safe to do so. 14. Use extreme caution and examine walls, floors, doors, staircases and windows to check for damage. 15. Be careful when driving after an earthquake and anticipate traffic light outages” American Red Cross. (2009) Earthquake Safety Checklist. http: //www. redcross. org/wwwfiles/Documents/pdf/Preparedness/checklists/Earthquake. pdf
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!!!!
