Researchers profile magma chamber beneath North Korean volcano

An enigmatic volcano straddling the border between North Korea and China has been investigated for the first time by an international team of seismologists. In 2013, researchers installed seismometers near the volcano — called Mount Paektu in North Korea and Changbaishan in China — to determine what was going on beneath the surface. The team’s results, detailed in a new study published in Science Advances, reveal a potential source of magma that may have created one of the largest volcanic eruptions in the last few thousand years — and that could cause the volcano to erupt again.

Sea-level rise a risk for millions in the United States

One of the most obvious consequences of human-induced global warming is glacial melting and the sea-level rise that will occur as a result. Yet, few studies examining the potential toll of sea-level rise in the United States have factored in continuing population growth, according to the authors of a new study in Nature Climate Change. Using population projections for the year 2100, researchers led by Mathew Hauer of the University of Georgia projected how many people in the U.S. would be displaced by then due to sea-level rise of either 0.9 meters or 1.8 meters.

Getting there and getting around Zermatt

Zermatt, a car-free resort town at the foot of the Matterhorn, can be reached from major international airports in Geneva, Zürich or Milan. All three airports offer nonstop flights from several North American cities and have numerous rental-car agencies. Switzerland has four official languages, of which German and French are the most commonly used, but road signs are easily followed by English speakers, making it easy to navigate around the country. However, private cars are not allowed in Zermatt, so you might instead want to take one of the Swiss Rail Network’s clean and reliable trains to Zermatt, a 3.5-hour trip from Zürich or a four-hour trip from Geneva. If you do drive, you must park in a garage in Täsch, 5 kilometers north of the resort town, and take a train or taxi into town. The village itself is quite walkable; a 10-minute stroll will get you across town.

Giant turbidite in Mediterranean Sea linked to ancient earthquake and tsunami

In A.D. 365, a giant earthquake with an estimated magnitude of 8 or higher struck the eastern Mediterranean, devastating Crete and causing widespread destruction throughout Greece, Egypt, Libya and Spain. The event was quickly followed by a tsunami that inundated the southern and eastern Mediterranean coasts, stranding ships as far as 3 kilometers inland. Now, scientists have uncovered evidence of a massive turbidity current triggered by these events in the Mediterranean.

Illustrating Geology: Great images that transformed the field

“The Map” is perhaps the single-most recognized depiction within geology, but it is just one of many historically transformative images in a field that relies heavily on illustration and visualization to help convey information and shape our understanding of the natural world.

Underwater archaeology reveals pre-Clovis people butchered mastodon in Florida

Evidence has been mounting for cultures older than the Clovis people, with archaeological sites and artifacts older than 14,000 years found as far south as Chile and genetic evidence dating the first incursions into North America to about 15,000 years ago. Now, a new study reporting on an underwater archaeological excavation at a site in Florida that dates to 14,550 years ago is adding more evidence of pre-Clovis people, and shedding light on how they may have spread across the Americas.
