Responding to earthquakes

How can we reduce the impact of seismic hazards?

What are the four strategies used for responding to earthquakes?

• prediction

• preparation

• adaptation

• prevention

Which three strategies are mitigation strategies?

• prediction

• preparation

• adaptation

How can the impact of seismic hazards be reduced by prediction?

• identifying regions at risk through plate tectonics

• close studies of fault lines

• seismic surveys

• monitoring groundwater levels

• monitoring the release of radon gas

• monitoring unsual animal behaviour

• attempts to predict a seismic event a few hours before are questionable

How can the impact of seismic hazards be reduced by preparation?

• education

• land-use planning

• insurance

• warning systems

• planned evacuation routes

• earthquake drills

• setting up search and rescue teams

• training exercises

How can the impact of seismic hazards be reduced by adaptation?

• earthquake proof buildings

• shatter resistant glass

• dampeners

• shock absorbers

• isolators

• testing earthquake proof designs

How can the impact of seismic hazards be reduced by prevention?

• building away from hazardous areas

• building giant sea walls to hold back tsunamis

• fire prevention
