Sinkholes

[ykhackhack]

Dear All

I am not geotechnical engineer. I have a question about any availability of a computerized , fast and efficient method ,machine for possible sinkhole survey of large areas.

I know we have some books in the forum, and also I can search the internet for this , but I was just wondering if anybody have any expert knowledge about this.

I keep seeing this horrific news about , cars falling in sinkholes, half of a house and people in it disappearing, etc

Thanks
