Drought: the Long, Slow Natural Hazard (Part 2)
In the second part of our two-part drought mini-series, we head down South to talk with USGS scientists Curtis Weaver and Brian McCallum about the drought situation in the Southeastern United States. We also learn some eye-opening economic implications of drought. (Did you know that it's possibly the most expensive natural hazard to address?)

Rabbit Hutch
A typical structure, or "hutch," for the management of rabbits for agricultural purposes and sometimes pet care. A wire base allows droppings to fall through to the ground.

10th anniversary of Kīlauea volcano's summit eruption
Today marks the 10th anniversary of the eruption within Halema‘uma‘u at the summit of Kīlauea Volcano. When the vent first opened on March 19, 2008, it formed a small pit about 115 feet (35 m) wide. Over the past decade, that pit (informally called the "Overlook crater") has grown into a gaping hole about 919 feet by 656 feet (280 x 200 m) in size.

Water-Quality Sampling
Noses Creek at Powder Springs Road, Georgia. Part of the USGS safety protocol is to wear a PFD (personal flotation device) around any surface water. This scientist may not look like he has one on, but he does--it is under his rain coat. This DH-81 sampler is used to sample flood water for suspended-sediment concentrations and water quality.

Alligator Resting in Afternoon Sun
Alligators are very abundant in the freshwater wetlands of Everglades National Park and can usually be seen along the Anhinga trail in the park, especially when water levels are low. This ~5-foot gator is resting on exposed limestone bedrock alongside the trail.
