GEOLOGY

Detailed explanation-1: -Mantle convection drives plate tectonics and deforms Earth’s surface, creating volcanic eruptions, earthquakes, tsunamis, and landslides, and sometimes causing great destruction.

Detailed explanation-2: -Geological natural hazards are for example earthquakes, land slides, sinkholes, volcanic eruptions and tsunamis. Geological natural hazards such as earthquakes and volcanic eruptions are triggered by activities taking place in the earth’s interior.

Detailed explanation-3: -Landslides of all kinds, including seismically-triggered landslides, debris flows, mud flows, and rock falls. Mineral hazards such as asbestos, radon, and mercury. Volcanic hazards, such as ash fall, lava flows, lahars, pyroclastic flows, toxic gases, and volcanic landslides.

Detailed explanation-4: -A geologic hazard is an adverse geologic condition capable of causing damage or loss of property or life. These geologic processes only become hazards when humans get in their way; if there were no people affected, we would find these natural phenomena interesting, but not concerning.

Detailed explanation-5: -A geological disaster occurs when natural geological processes impact on our activities, either through loss of life, injury, or economic loss. The Geological Survey has compiled a historical record of geological disasters from a wide range of sources over several years of research.
