1.11 Managing the Impacts of Tectonic Hazards Flashcards
what are the 4 hazard mitigation strategies?
land use zoning
diverting lava flows
GIS mapping
hazard resistant buildings
what is land use zoning?
local governments regulating how the land is used
e.g. not building on hill slopes at risk of landslides
what is diverting lava flows?
using dynamite to create channels and craters for lava to flow into away from developed areas
e.g. 1988 Mount Etna
what is GIS mapping?
planning out evacuation routes
e.g. Nepal 2015
what are hazard resistant buildings?
buildings that can resist a natural hazard
e.g. sloped roofs prevent ash build-up
e.g. cross bracing buildings to withstand ground shaking
elevated buildings at risk from flooding from tsunamis
seawalls built along coastlines at risk from tsunamis
what is the aim of hazard mitigation strategies?
avoid, delay or prevent hazards
what are the 6 hazard adaption strategies?
GIS
early warning systems
mobile phones
crisis mapping
modelling hazard impacts
public education
what is GIS?
creating a hazard map of where is at a greater risk
what is an early warning system?
detect tectonic activity so warnings can be sent out a people at risk can be evacuated
how do mobile phones help with adapting to hazards?
governments can communicate with people on what they need to do
people trapped can let other people know
what is crisis mapping?
a map created showing where people are trapped or in need of help
how does modelling hazard impacts help with adapting to hazards?
scenarios can be created so there is more efficient evacuation
how does public awareness help with adapting to hazards?
more people know what to do in a hazard
what is the aim of hazard adaption strategies?
reduce the impacts of a hazard
who are the 4 key players in managing loss?
aid donors
NGOs
private investors
local communities
