the concept of hazard in geographical context Flashcards
primary effects of tectonic hazards
- electricity, water and communications disrupted
- deaths and injuries
- infrastrucutre and homes destroyed
- intense shaking
secondary effects of tectonic hazards
-disease
-trauma and stress
-homelessness, social disorder, damaged economy
-tsunami, mass movement
immediate responses to natural hazards
-search and rescue
-emergency aid
-resources
-financial aid
-shelters
-communications
-clearing damage
long term responses to natural hazards
-infrastructure rebuild and improve
-investment and development
-boosting tourism
-housing reconstruction
the hazard management cycle
preparedness: public awareness, education, training
response: evacuation, medical assistance, rescue
recovery: restoring services, reconstruction
mitigation: barriers, warning signals, observations
hazard management general
monitoring - detecting and recording physical changes
predicting - using monitoring and historical trends to predict tectonic hazards
protecting - increasing resistance
planning - evacuation in place
parks model response
- relief - immediate local/global response in form of aid or search and rescue
- rehabilitation - longer phase lasting weeks or months - infrastructure and services are restored
- reconstruction - restoring to the same level pre disaster
the richter scale
energy released is proportional to the magnitude 0-9
