When the gravity of the Sun and Moon causes Earth's crust to bulge every 2 weeks, slow-moving earthquakes proliferate in the lower reaches of the San Andreas, a new study finds.

hq环球体育: 5. Revising the Displacement History of New Zealand's Alpine Fault
A reinterpretation of structural and paleomagnetic data suggests that New Zealand's Alpine Fault accommodates a far greater percentage of geologically recent plate motion than previously thought.

New fieldwork and satellite data suggest that three faults may have caused a large earthquake near Almaty, Kazakhstan, more than a century ago.

Although damage from the specific incident "is relatively well contained," the issue threatens the agency's reputation for high-quality science and goes counter to its standards, according to a USGS official.

hq环球体育: 1. Predicting the export and fate of global ocean net primary production: The EXPORTS
Earth’s carbon cycle is heavily influenced by ecological processes in the ocean. The quantification and understanding of the intricate relationships between carbon dioxide and ocean ecosystems, and what effects these have on the present and future conditions on Earth, is one of the greatest challenges in oceanography. One of the most important aspects that preclude the full understanding of the ocean carbon cycle is the lack of parallel measurements at a global scale; this also hinders our ability to make robust predictions in an uncertain future.

Over the past few winters, Gabriele Messori and his colleagues have noticed an intriguing weather pattern: bitterly cold days in the eastern United States were often followed by extremely wet and windy weather in Europe.

hq环球体育: 1. Sj?gren Glacier Fast Flow, Fast Retreat, Antarctica
Sj?gren Glacier flows east from the northern Antarctic Peninsula and prior to the 1980’s was a principal feeder glacier to Prince Gustav Ice Shelf. This 1600 square kilometer ice shelf disintegrated in the mid-1990’s and was gone in 1995 (Cook and Vaughan, 2010). Scambos et al (2014) noted a widespread thinning and retreat of Northern Antarctic Peninsula Glaciers with the greatest changes where ice shelf collapse had occurred, Sj?gren Glacier being one of the locations. Scambos et al (2004) first documented the acceleration of glaciers that fed an ice shelf after ice shelf loss in the Larsen B region. A new paper by Seehaus et al (2016) focuses on long term velocity change at Sj?gren Glacier as it continues to retreat. This study illustrates the acceleration is long lived with a peak velocity of 2.8 m/day in 2007 declining to 1.4 m/day in 2014, compared to a 1996 velocity of 0.7 m/day, which was likely already higher than the velocity in years prior to ice shelf breakup. Here we examine Landsat images from 1990, 2001, 2005 and 2016 to illustrate changes in terminus position of Sj?gren Glacier
hq环球体育: 2. Gangotri and China: three fascinating new landslide videos
As Asia reels under extraordinary rainfall under strong monsoon conditions, three new, interesting landslide videos have been posted on Youtube. The first shows a rather elegant rockslide on the highway to Gangotri in Uttarakhand in northern India.
