Predicting when earthquakes will happen and when volcanoes will erupt
By studying how the earth's crust reacts to earthquakes, volcanoes, or underground explosions and the like.
They may be known as faults, joints or more generally as discontinuities. Please see the related links for more information.

There are several reasons: * To inform other scientists who are interested in the same sort of thing of the progress that has been made. Others can either stop looking, incorporate their answer to part of the question that was puzzling them, or move onto the next stage of the problem. * To establish that they were the first to discover the answer to a problem. This provides "bragging rights" and helps them become credible in their community. Publicity is an essential part of getting more money for future research etc * To promote peer review and comment. Everyone is blind to their own faults. Different eyes may see problems that the first researcher has missed

Geologists collect data on friction along the side of faults so that they can predict how much pressure is applied on the faults so they can predict how strong the earthquake is.

By using friction. Without it, they wouldn't have anything so the two will have also faults along the friction
Friction between rocks on each side of the fault.
So that geologist can predict how much force of pressure applied on the faults to predict how strong the earthquake.
to detect a slight rise or fall in the elevation and tilt of the land.
Geologists study the types of movement that occurs along faults. How rocks move along a fault depends on how much friction there is between the sides of the fault. Friction is the force that opposes the motion of one surface as it moves across another surface. Friction exists because surfaces are not perfectly smooth.Along parts of some faults, the rocks on both sides of the fault slide by each other without much sticking. Therefore stress does not build up, and big earthquakes are unlikely. Along many faults, the rocks lock together. In this case, stress increases until it is large enough to overcome the friction force. Stress builds up until an earthquake occurs.
