This time-lapse video shows the dramatic natural tidal cycles of a salt marsh in San Francisco Bay -- daily rhythms to which animals take refuge in high ground, and the marsh receives sediment and nutrients from the estuary. But what will happen to these marsh ecosystems under sea level rise scenarios?

USGS emeritus geologist RobertFournier describes his career working on Yellowstone geysers and hydrothermal systems from the 1960's through 2014. Bob's work along with his USGS colleagues revealed the details of Yellowstone's explosive volcanic past and how its spectacular geysers and other hydrothermal features work.

USGS emeritus geologist Robert Christiansen describes his career working on Yellowstone geology from the 1960's through 2014. Bob's work along with his USGS colleagues revealed the details of Yellowstone's explosive volcanic past including mapping and dating of past super eruptions 2.1 million years ago, 1.3 million years ago and 640,000 years ago.

USGS emeritus geologist Patrick Muffler describes his career working on Yellowstone geysers and hydrothermal systems from the 1960's through 2014. Patrick's work along with his USGS colleagues revealed the details of Yellowstone's explosive volcanic past and how its spectacular geysers and other hydrothermal features work.

As one of the most populous countries in the world, India faces an energy crisis. Daily energy demands often exceed local production capacity. Solutions to this challenge may be found in the development of wind, solar, biomass, hydropower and nuclear energy. These sustainable sources of energy may gradually replace energy derived form hydrocarbons.

The December 2004 Indian Ocean Tsunami was one of the deadliest natural disasters of modern history, killing over 225,000 people. As a result of this catastrophe, the U.S. Geological Survey has partnered with the international community to create an Indian Ocean Tsunami Warning System (IOTWS).

This film depicts the effects of the Wenchuan Earthquake in China on May 12, 2008. This was filmed May 23-26, 2008 in Sichuan by Yingying Huang. The film captures the devastation of the Wenchuan Earthquake as experienced by the local population, as well as effects on the buildings and monuments.

This film presents a summary of the natural hazards and resources of Thailand. It explores the different types of hazards that Thailand needs to be prepared for: flooding, drought, storm surges, earthquakes, and tsunamis. This film also presents the Thai Meteorological Department that monitors and reports earthquake and tsunami activity.

This film presents a summary of the natural hazards of Hong Kong. Such natural hazards include earthquakes, typhoons, tsunamis, and landslides.
