Erosion.

13.Equally threatening besides volcanoes are earthquakes ?

14.What does earthquake preparation consist of?

Make buildings earthquake resistant; laws that prevent new building on faults; building codes that make new building quake resistant.

15.What is the dual role that geologist must play?

They help in the process of where a building can be built. If the land soil is prone to earthquakes, the geologists can say yes or no.
