Help in Haiti - The Role of Science
In response to the 7.0-magnitude earthquake that tragically struck Haiti on January 12, 2010, the U.S. Geological Survey has coordinated a series of trips to the country to characterize the damage and install seismic instruments for earthquake monitoring. USGS seismologist Walter Mooney, who returned from the first of the series of trips in early February, discusses the
Fatal Frog Fungus
The potentially lethal fungal disease chytridiomycosis has been associated with declining amphibian populations around the globe. This rapidly emerging disease, and the chytrid fungus that causes it, have forced scientists to scramble to learn more. There are still plenty of mysteries about the origin and spread of the fungus. With today's episode we will shed some light
Public Lecture Sneak Peek: ARkSTORM
- Scientists are preparing ARkStorm for emergency planning and disaster preparedness
- A series of ‘Atmospheric River’ events slams into the West Coast with hurricane force overal several weeks
- Weather models show expected hazards such as floods, landslides, and erosion impacting life and property
- Storms of this magnitude are projected to become
Disappearing Ice Shelves on Antarctic Peninsula
Ice shelves are retreating along the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues.
USGS scientist Jane Ferrigno discusses the USGS project that is for the first time studying the entire Antarctic coastline in detail.
USGS Hydrologic Investigation of West Africa's Congo River (part one)
USGS South Carolina Water Science Center Data Chief, John Shelton in a special hydrologic expedition down the Congo River, West Africa. Part one of a three part episode, sets the stage for the trials and tribulations of water investigations for a changing world.
USGS Hydrologic Data Collection Program in North Carolina
USGS North Carolina Data Chief, Jeanne Robbins, provides an overview on hydrologic data collection techniques for North Carolina.
Debris Flow Danger Follows Storms in Southern California
The powerful storms that swept through Southern California dumped a lot of rain in that region, leaving behind the danger of debris flows.
Sue Cannon, USGS research geologist, explains the hazardous situation facing residents in and near the San Gabriel Mountains, how people in the area can respond to these hazards, and what the USGS is doing to respond.
Northwest Mussels Live Long to Tell Their Story
Few would believe the importance of freshwater mussels to scientists here in the Pacific Northwest. These little-known and often-ignored organisms may live for over a century on the bottoms of lakes, rivers, and streams. Freshwater mussels have a story to tell, and researchers have developed a way of ‘reading’ this story. USGS Aquatic Biologist Jason Dunham discusses his
Aftershock Hazards in Haiti
The aftershock sequence of the magnitude 7 earthquake that struck Haiti on Jan. 12, 2010, will continue for months, if not years. The frequency of events will diminish with time, but damaging earthquakes will remain a threat.
Michael Blanpied, USGS Associate Earthquakes Hazards Program coordinator, discusses concerns and precautions for the future in Haiti and the
The Haitian Earthquake - A Week Later
As Haiti copes with the aftermath of the magnitude 7 earthquake, which struck on Tuesday, January 12, 2010, the U.S. Geological Survey is working to gather information that can aid response efforts. Michael Blanpied, USGS Earthquakes Hazards Program coordinator, gives an update on the current situation in Haiti and answers questions about the global picture.
Magnitude 7.0 Earthquake Strikes Haiti
On January 12, 2010, Haiti was struck by the most violent earthquake in a century. Michael Blanpied, associate coordinator for the USGS Earthquake Hazards Program, answers questions about the earthquake, its severe shaking, and the possibility of additional hazards, such as landslides and a tsunami.
A Potent Pollutant is Tracked Indoors
Carcinogenic compounds in a popular pavement sealer are tracked indoors, where they show up in high concentrations in house dust.
Listen as USGS hydrologist Barbara Mahler explains how she and her team identified the link between polycyclic aromatic hydrocarbons in coal-tar-based pavement sealcoat and house dust.
Want Clues to Future Climate? Let's Look Back 3 Million Years.
Scientists have reconstructed what the climate conditions were 3 million years ago, and are using these data as one of the closest analogs to estimate future climate conditions.
USGS scientists Harry Dowsett and Marci Robinson discuss some of their findings regarding carbon dioxide’s impact, Arctic conditions, and the deep ocean’s system.

Magnitude 5.8 Earthquake in Northwest Mexico
A magnitude 5.8 earthquake occurred just south of the California-Mexico border shortly before 11 a.m. on Wednesday, December 30, and shaking from this earthquake was widely felt.
