The study of natural events such as tornadoes, forest fires or landslides are explored within the  physical branch of geography.

Explanation:

Physical geography talks about the natural processes of the earth that shapes the earth surfaces , the rocks formed and the spatial pattern . This branch of geography gives you the idea on how the hydrosphere, lithosphere, atmosphere and biosphere interact to change the land surface.

The natural process can be amplified by the biosphere to speed up the earth processes. Like in the case of erosion and weathering. Anthropogenic activities could amplify natural events like the forest fire when they burn bushes for farming. if the climate is  favorable to cause wild fires, the event becomes uncontrollable.

Landslides are caused when sediments and rocks on a slope becomes unstable. This disintegrated rocks particles later slides or slumps downward as gravity tends to increase the rate of sliding. But if friction is greater than gravity the rocks will not slide.

Tornado are natural events which  causes rotation of air in the atmosphere
