Photos from Dauphin Island indicate beach erosion and island overwash, furthering the erosion the island has seen during repeated storm events -- Ivan, Katrina, Gustav and Isaac -- that have led to the island's increased vulnerability to future storms.  

USGS researcher Craig Allen stands on the edge of Mesa Alta, amid diverse forest and woodland in the uplands of northern New Mexico; note some recently dead ponderosa pine and Douglas-fir in the field of view. Forest drought stress is strongly correlated with tree mortality from poor growth, bark beetle outbreaks, and high-severity fire.

A magnitude 4.8 earthquake struck the island of Anjouan in the Union of the Comoros on March 12, 2014.  Heavy rainfall trigger landslides and damages were incurred to buildings, roads, and water supplies. As a precaution, more than 3,000 citizens living below the landslides were moved to a refugee camp.

Heavy rains from a tropical cyclone struck the islands of the Comoros in March, 2014. On the island of Anjouan in the Union of Comoros, these rains triggered landslides that displaced over 3000 people to refugee camps. The USGS and the OFDA with USAID are providing support and research assistance on these events.
