Do you have questions about the minerals, rocks, valleys, canyons, mountains, rivers, volcanoes, earthquakes, earth fissures, landslides, or natural hazards of Arizona?

Natural hazards abound in Arizona. At the top of list: flash floods, severe weather, landslides and debris flows, earthquakes, and earth fissures.

Karst features and landscapes occur where rocks prone to dissolution by weakly acidic natural waters occur at Earth’s surface or in the shallow subsurface.

Earth fissures and subsidence threatens people and livestock, damages homes, roads, dams, and canals, and reduces property values.

arth fissures are open surface fractures that may be up to a mile in length, up to 15 ft wide, and 10s of feet deep.

Floods occur in each state and cost upwards of six billion dollars annually, disappearing as suddenly as they appear, leaving destruction and sometimes death in their wake.

Damage to structures in Arizona is commonly related to soil characteristics – shrink/swell soils and collapsing soils. Shrink/swell soils cause more damage to homes than do floods, tornadoes, and hurricanes combined.

Landslides in Arizona destroy homes, damage roads, disrupt utilities and infrastructure, and lead to deaths and injuries.

In Arizona, volcanic rocks and features are ubiquitous in space and time
