The USGS assists FEMA with updating flood insurance rate maps throughout New England. This is in response to recent major flooding events and because of the need to update the 30 year-old effective flood insurance rate maps. This video gives a brief overview of the FEMA project team with a focus on the surveying component of the project.

 

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance.

An earthquake and tsunami in March of 2011 leveled cities and left 18,000 people dead along the east coast of Japan. The government responded with a plan to build hundreds of sea walls in hopes of protecting coastal communities from future disasters. Rikuzentakata was among the cities fortified after the tragedy.

On October 17, 1989, at 5:04 pm a magnitude M6.9 earthquake struck near Loma Prieta, California. It was a tragic reminder of the destructive power of earthquakes. However, it was also a watershed moment in seismic research. 30 years later, we revisit the earthquake through the eyes of the scientists who experienced it. And studied it. These are their stories.

Remembering the Loma Prieta Earthquake 30 Years Late: Looking back to see how far we've come.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of September 2019.

 

Retired seismologist David Oppenheimer reflects on the first prototype earthquake early warning system used during the 1989 Loma Prieta earthquake. Scientists deployed an analog system to notify first responders of impending earthquake activity as they worked on rescue efforts at the Cypress Viaduct collapse in Oakland, CA.
 

USGS Hawaiian Volcano Observatory scientists Matt Patrick and Jim Kauahikaua talk about the water that appeared at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano, in July 2019 and continues to rise today. They address why it appeared, how it’s monitored, and its potential hazards.

Tidal marshes exist as a transitional environment between the land and sea, and provides habitat to fish and wildlife, protects human developments from coastal flooding, and stores carbon at high density, among other important ecosystem services.

This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image).

This time-lapse video shows circulation in the water pond in Halema‘uma‘u over a period of about 25 minutes. There appears to be an influx of water along the southern (right) shoreline. A broader eastward flow of water (toward top of image) is evident. The video is shown twice. USGS video.

Views of the water pond in Halema‘uma‘u on Friday, September 6, and Monday, September 9 are shown in this video. Ripples are evident on the pond, presumably due to wind moving over the water surface. No significant changes in the pond were observed over the weekend, and the water level continues to slowly rise. USGS video by M. Patrick.

Shown at 30x speed, this video highlights changing activity on the surface of the water pond. Steam wafting above the pond shifts in the wind, and circulation of the water is evident in areas of sharp color boundaries. USGS video by M. Patrick, 09-17-2019.

Abnormally high spring rainfall and subsequent flooding in the Midwest had a season-long impact on cropland production. In these Landsat images of South Dakota growing vegetation is shown as green and unplanted areas appear pink. The difference between 2018 and 2019 is striking.

This video was taken during the SW1321 training course, Streamflow Measurements Using ADCPs. On this field day, students from all over the USGS used their newfound knowledge to collect ADCP data in Windham, Maine.
 

In July, satellite imagery from Landsat 8 captured a major melting event in Greenland.
