- After the smoke from wildfires clears, debris flows can become a big problem. USGS Research Geologist Sue Cannon talks about how.
- Mount St. Helens and surrounding area recover from the historic May 1980 eruption. Shades of white and gray indicate still-bare slopes that were swept by volcanic flows; light green areas at the top of the photo show regrowth of vegetation in devastated areas; dark green areas at the bottom were unaffected by the eruption.
- 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.
