Oil extraction likely triggered mid-century earthquakes in Los Angeles
Six independent earthquakes and two aftershocks of magnitude 4.4 to 5.1 shook LA between 1935 and 1944, a rate of about one every two years. A new study re-examined historical information about the earthquakes from archived damage reports to refine the earthquake locations identified by early earth-motion sensors, placing them closer to many active oil fields.

Scientists test less invasive methods of locating oil in deep sea
New techniques for finding oil beneath the seafloor could reduce the frequency of seismic testing or exploratory drilling, which is harmful to marine animals, according to new research.

North Dakota’s Bakken oil and gas field leaking 275,000 tons of methane per year
Researchers found that 275,000 tons of methane leak from the Bakken oil and gas field each year, similar to the emission rate found for another oil-producing region, Colorado’s Denver-Julesburg Basin. That’s the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana.

Weathering the Gulf cleanup: Providing better forecasts over water
Responding to the Deepwater Horizon spill in the Gulf of Mexico has required hundreds of ships and steady air traffic – both of which depend on having accurate weather forecasts to operate safely. Unfortunately, meteorologists haven’t have the ability to track weather conditions as well over the water as they do on land, which can lead to less accurate weather forecasts. To address that need, the National Weather Service asked atmospheric …
