Watch video above to see these stories on AZ Illustrated Science on Tuesday, Sept. 24:

VALLEY FEVER: Valley fever is a lung disease that affects humans and some animals, such as dogs and cats. It is caused by a fungus, called coccidioides, which lives in the soil in the Southwestern U.S. and northern Mexico. The fever is common enough in Arizona to keep physicians very, very busy. Although valley fever is common in the Southwest, it's routinely misdiagnosed.

EARTHQUAKE MONTH: September is also national earthquake preparedness month. While earthquakes are infrequent, they can occur in the state, and at high magnitudes. Approximately 90,000 Arizonans have signed up to take part in an event to learn what to do in case of an earthquake. The Great Arizona ShakeOut will last about two minutes, at 10:17 a.m. on Oct. 17.

HAZARD VIEWER: The Arizona Geological Survey has announced the release of its new hazard viewer. The site is a compilation of data on earthquakes, faults, earth fissures and wildfires in the state. The survey originally planned the site for first responders, but later decided the general public is also in need of this information. Visitors to the site can view a statewide map of natural hazards, or they can type in an address to find local hazards.

SONORAN DESERT VENOM RESEARCH: The Sonoran desert is Ground Zero in the U.S. for venomous animals. Species, such as the Black Widow spider and rattlesnakes, populate the landscape. This grand amount of venomous animals, means the production of anti-venoms is very important, as they can be life savers.
