Goals for today:

1. You can name three ways of dealing with disasters
2. You can explain what hazard management is
3. You can name the three types of hazard management measures
4. You can name at least two measures to reduce the impact of an earthquake

§4.5 Resources: Dealing with disasters

Sub-question:
How can the effects of natural disasters be mitigated?

Hazard management

Hazard management = The strategy that aims to prevent damage by natural disasters

 

• 3 Components

1. setting up warning system
2. taking construction measures
3. making emergency plans

Will there be a volcanic eruption?

The following omens may lead to a volcanic eruption:

• rise of magma causes earthquakes
• warming of the environment 
• expansion of the volcano. The volcano emits more sulfur and makes certain noises.

What should you do if there is an earthquake and you are inside?

1. sitting under the table
2. running out of the house
3. don't move
4. go to the corner of the room

Predicting an earthquake

Seismologists create maps of areas showing the likelihood of earthquakes. Based on these, evacuation plans are made, buildings and pipelines are made earthquake-resistant.

-Predicting a tsunami

If there is a seaquake, the alarm is raised and the posts around the warning system can be notified. The authorities can then start evacuating the population from the threatened areas.

Predicting a typhoon

On satellite images, meteorologists can recognize the formation of a typhoon. Then they start trying to predict the hurricane's path. This is difficult, which is why the decision to evacuate is often difficult.

Why would there be less damage from disasters in countries with high levels of development (rich countries)?

What are omens of a volcanic eruption?

What are the names of the researchers who study earthquakes?

Why are floaters important for predicting a tsunami?

What are the three ways of disaster response?
