New study identifies next faults to fail along California-Nevada border
A handful of faults lining the border of California and Nevada may be near the point of rupture, according to a new study assessing earthquakes in the region as far back as 1,400 years ago. Scientists report that earthquakes in a fault network east of the Sierra Nevada Mountains are not random, but are likely triggered from stress bestowed by past earthquakes. This same type of stress has built up in six faults near Death Valley, California, and Reno, Nevada, according to the new research.

Dormant volcano near Rome is waking up
A long-dormant volcano outside Italy’s capital is entering a new eruptive cycle, a recently published study finds. Scientists previously assumed Colli Albani, a 15-kilometer (9-mile) semicircle of hills outside Rome, was an extinct volcano. But in recent years, scientists have observed new steam vents, earthquakes and a rise in ground level in the hills and surrounding area.

Odd behavior of Jovian moon dust could inform future space missions, search for life
New research into the movements of dust around Jupiter’s four largest moons could help scientists searching for life in our solar system, according to a new study. This moon dust around Jupiter could give scientists clues about the composition of the surface of its satellites.

The Struggle to Survive
Tubeworms are unusual creatures. They have no eyes (there is no light where they live) and they do not have what we think of as a mouth or stomach. The way they survive is with a mutually beneficial relationship with other creatures. Instead of taking up food with the mouth, little gutless tubeworms house sulfur bacteria in their body.

The University of Washington’s eScience Institute, a unique environment for geospatial data science education
Earth scientists can choose from an ever-increasing array of datasets when they set out to study our changing planet. Every year, advances in remote sensing and sensor network technologies increase in resolution, streaming data to us on demand, in real time. If you’re like me, you find this new era of discovery exhilarating but also overwhelming. How will I ever find the time to learn the software and cloud technologies needed to keep up with this flow of new information?

Melt-driven streams on Greenland’s ice sheet shape landscapes faster than rivers on land
Erosion by summertime melt-driven streams on Greenland’s ice sheet shapes landscapes similarly to, but much faster, than do rivers on land, according to a new study. The approach used to study the drainage system of the ice sheet should serve to broaden the scientific understanding of melt rates and improve projections about ice sheet response to climate change, said Leif Karlstrom, a geologist at the University of Oregon in Eugene and lead author of the study.

Embarking on a research cruise
This week I will fly to Oregon to meet up with scientists from Oregon State University and embark on my first research cruise. I will be an observer aboard the R/V Oceanus, a mid-sized research vessel owned by the National Science Foundation and operated by OSU. We will be out on the ship for a week, traveling up and down the Pacific Northwest coast, and I’ll be blogging, taking pictures and shooting video to capture both the research being done and the experience of being aboard a research ship.
New Zealand’s Alpine Fault biggest mover in the world
New Zealand’s Alpine Fault has moved more in the last 25 million years than any other known land fault on Earth, according to new research. Findings of a new study reveal that over this time period, the two sides of South Island have shifted relative to each other more than 700 kilometers (435 miles),which dramatically changes our understanding of New Zealand’s tectonic movements.
