In 2013, researchers uncovered the graves of two infants laid to rest about 11,500 years ago outside of what is now Fairbanks, Alaska. Researchers understood that these graves represented some of the earliest human migrants to North America, but were they more closely related to their Asian ancestors, or the modern-day residents of North and South America? Using mitochondrial DNA analysis of the infants, what could we learn about our own human history?

We're most accustomed to flooding causing levees to fail, like they did in New Orleans during Hurricane Katrina. So although the El Nino-induced floods are making the most news in California right now, it's not actually the floods that are threatening some California levees the most. Instead it's the severe drought over the last four years that has taken its toll on thousands of kilometers of century-old earthen levees.

A magnitude-7.1 earthquake struck Chile on Jan. 2, 2011, or so scientists thought. Now, with increasing sensor sensitivity and advances in the quantitative analysis of earthquakes, scientists have revealed that this quake was actually a doublet. This meant that instead of just one massive quake, two similarly large earthquakes struck very near to one another within seconds. The closely spaced doublet was missed by global monitoring networks during the initial aftermath of the quake, and, as EARTH Magazine explores, it presents a major challenge to earthquake and tsunami warning systems. Experts agree this is a challenge that must be brought to the forefront of seismic research.

More than half of the total human population on Earth lives in urban areas, where, like rural areas, geology affects us every day. Yet when we think about "geology," most of us think of the hinterlands. That needs to change, argue the authors of a new feature in EARTH Magazine discussing what the role of urban geology is, what it can be and the potential role geoscience organizations can play in curating the geologic data revealed during construction, excavations and surveys.

As skiers hit the slopes this winter, EARTH Magazine explores the science of how to keep them and other winter explorers safe. Every year, hundreds of people are killed by avalanches. Understanding the science of the frozen environment is only part of this story; communicating the risk is a field as dynamic as the weather systems and terrains that foster avalanches.

Tsunami hazard maps exist for California coastlines, but recent geological studies indicated some faults may be capable of unleashing more powerful quakes than previously thought. Given this new information, researchers at the University of California Riverside wondered if the current tsunami hazard maps adequately predict inundation zones, or if they need to be updated.
