Current Mitigation Technologies for Sinkholes 2

What is mitigation?

 Mitigation means to reduce the seriousness or sadness from something.

When it comes to natural disaster, mitigation means to help protect someone or something, or help someone or something fix a problem

What mitigation technologies currently exist for your natural disaster?

• Scientists have come up with Radar technology, which  transmits electronic pulses to let people know when a sinkhole is about to happen

What are the pro’s and con’s of some of the mitigation technologies currently available?

Why is it important to advance or totally replace the existing technologies?

• The pros are that the radar helps scientists see if the earth's crust is shifting

Basics of sinkholes 1

How does a sinkhole form?
- A sinkhole forms where there is soluble rock can be dissolved by water, therefore the material should be limestone or gypsum

- As water flows through the ground, it filters its way through the grains of dirt, rock and sand in the top soil and even through the grains of the underlying bedrock.

- For a sinkhole to form, the area must be damp and shallow 

Where sinkholes are common: 

• Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them.

Places Where severe sinkholes have occurred:

-Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.

What are the effects of a sinkhole?

• Sinkholes could damage homes
• Could injure people
• Could kill people
• Could destroy environment
• Could destroy pipes
• Could kill or injure animals
• Could cause economic loss

Some economic costs of a sinkhole to look out for:

• Businesses will be closed
• Schools will be closed
• People will lose their homes
• People will lose their cars
