The crumbling Coastside: Winter leaves ominous signs of erosion — Apr. 2016
“A more recent USGS study showed that, along a stretch of coast from Daly City to Pacifica, the rate of erosion over the last several decades has increased dramatically. Just how bad is it? ‘Fifty percent over the long-term historical rates,’ wrote USGS Coastal Geologist Patrick Barnard in an email to the Review. The change illustrates an increase from 1.3 feet per year to 2 feet per year.”

Video: USGS says it’s getting closer to predicting landslidesKRON 4, Mar. 2016
“The United States Geological Survey said they are getting closer to being able to predict landslides.”

Potential for Landslides in Pacifica Reach 'High Risk Zone': USGS — NBC Bay Area, Mar. 2016
“Geologists with the USGS said the potential for landslides in Pacifica has now reached a risky level, adding to the concerns homeowners along the coast have over erosion.”

Living on the Edge: County weighs Sisyphean task of managing cliff erosion as coastline recedesGoodTimes, Mar. 2016
“This winter has the largest waves on record, and wave energy is 30 percent higher than average, according to the USGS. The bigger the wave and the higher the tide, the greater the damage—and in El Niño years like this one when sea levels rise, the threat of cliff failure also increases.”

RISING SEAS: El Niño pummels coast in preview of warmer worldE&E Publishing Greenwire, Feb. 2016
“Wave energy, judged by its size and force, usually increases by 20 to 30 percent during El Niño years, USGS's Patrick Barnard said.”

Pacifica: Amid El Niño, city backs controversial coastal developmentSan Mateo County Times (San Jose Mercury News), Feb. 2016
“As much as half of the property could be eaten away by the year 2100, according to coastal erosion predictions produced by Our Coast, Our Future (a collaboration between government agencies such as the U.S. Geological Survey and nonprofits).”

Prodigious plumes present provocative puzzleWest Hawaii Today, Feb. 2016
“According to the latest forecasts, we can expect this year’s El Niño to hang on until early summer (kau wela). If this prediction comes true, it’s likely that tall, vertically rising eruption plumes will adorn the skies above our steadily active volcano, giving Kilauea’s dedicated observers plenty to watch.”

Bay Area Landslide Risk Goes Up as Rains Pour DownKQED Science, Feb. 2016
“How bad this year will be for landslides all depends upon how intense the rains will be,” says Brian Collins, a researcher at the U. S. Geological Survey in Menlo Park. “The water has been pretty constant so there is a danger.”

Perilous cliffhangers of Pacifica tell a cautionary tale — SF Chronicle, Jan. 2016
“The evacuation this week of a third 1960s-era apartment complex teetering on the edge of sheer cliffs in Pacifica was a climax in a slow-motion disaster made possible by a development boom that geologists now see as a lesson for California on how not to build on the coast.”

El Niño lets landslide scientists get back to their researchSan Jose Mercury News, Jan. 2016
“Jonathan Stock, a research geologist at the USGS in Menlo Park, and his colleagues set up four monitoring stations mostly to address the timing—the ‘when’—of shallow landslides.”

What to Know Before Buying a Home on a CliffRealtor.com, Jan. 2016
“The U.S. Geological Survey—which studies the impact of storms and erosion on shorelines—has found that the cliffs in Pacifica have been retreating at an average rate of about 2 feet per year since 1950.”

The state, the drought and El Niño: It’s complicatedUC Berkeley News, Jan. 2016
“B. Lynn Ingram, a geologist specializing in paleoclimatology, studies past climate history by examining natural archives — trees, sediments, shells, microfossils — and takes a long-term perspective to predict what the climate could have in store for us.”

“Yes, it’s raining and snowing, but drought damages must be addressed.”

Pajaro Valley farmers cautiously optimistic about El Nino — Santa Cruz Sentinel Weather, Jan. 2016
“The much anticipated arrival of rain means local agricultural can start shifting gears, but they’re not overly optimistic because the drought isn’t over yet.”

El Nino Fuels Mudslides, Hard to Predict WhereDiscovery.com News, Jan. 2016
“According to the USGS [Landslide Hazards] website, the most serious immediate risk is from shallow landslides that become so wet that they can move rapidly over long distances ...up to 35 miles per hour.”

Tracking San Diego River Levels During El Niño StormsKPBS.com, Jan. 2016

Starvation suspected in massive die-off of Alaska seabirdsAP.com's The Big Story, Jan. 2016
“An estimated 8,000 common murres were found dead on the Whittier beach, said John Piatt, research wildlife biologist at the U.S. Geological Survey's Alaska Science Center... Warmer water surface temperatures, possibly due to global warming or the El Nino weather pattern, may have affected murre prey.”


Debris flow and recent burn areasLA Times.com, Dec. 2015
“The U.S. Geological Survey has studied select fire burn areas to determine their vulnerability to flash floods and debris flows.

California's drought plus El Niño increase the threat of a muddy disasterLA Times.com, Dec. 2015
“Debris flow has long been a concern in areas where wildfires have recently burned. Vegetation, once burned, can no longer hold back loose sediment. The burned slopes can also become 'water repellent,' said Jason Kean, a U.S. Geological Survey hydrologist whose research focuses on debris flow.”

Slip-sliding Away: Heavy El Niño rains could trigger mudslides in California this winter; these scientists are trying to figure out the whens and wheres — OnEarth.com, Dec. 2015
“Brian Collins, an engineer and landslide expert with the U.S. Geological Survey in Menlo Park, California, says, 'We learned [from strong El Niños in the past] that sandier soils, rather than clay soils with small particles, tended to cause debris flows that careened out into neighborhoods.'”
