The correct answer is Tropical cyclone.

Key Points

•  Geological hazards, including volcanoes, earthquakes and landslides, can be dramatic and violent events with far-reaching and devastating impacts.
• Impacts on human health can still be felt years after the event has actually occurred.
• Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the Earth.
• Ballistics comprise fragments of magma and old (i.e., pre-existing) rocks ejected during an explosive eruption at variable velocity and angle on cannon ball-like trajectories; they are not entrained within the volcanic plume and are dispersed in proximity to the vent (typically <5 km)
• Landslide is the downslope movement of soil, rock and organic materials under the effects of gravity, which occurs when the gravitational driving forces exceed the frictional resistance of the material resisting on the slope. Landslides could be terrestrial or submarine
• The Centralia mine fire is a coal-seam fire which has been burning in the labyrinth of abandoned coal mines underneath the borough of Centralia, Pennsylvania, United States, since at least May 27, 1962.
