he American Geosciences Institute is honoring one of the scientists who advanced earthquake hazards preparedness and mitigation in the U.S. by his superlative service to the earth sciences. This year’s recipient of the Ian Campbell Medal, Dr. James “Jim” Davis, is one of the key scientists behind U.S. earthquake hazards and loss reduction policy as it is known today.

If Earth breathes, Santiaguito Volcano in the Western Highlands of Guatemala could be its mouth. Roughly every half hour, like volcanic clockwork, Santiaguito’s active Caliente lava dome expands, filling with gas from depressurizing magma below. Then it exhales, often explosively, and deflates. Over the course of a day, you could almost keep time by it.

“Virtual water” was coined in 1993 to help explain why long-predicted water wars driven by water and food security had not occurred among the arid nations of the Middle East and North Africa. The virtual water notion refers basically to the total amount of freshwater, either from rainfall or irrigation, used in the production of food commodities, including crops and fodder-fed livestock, or other goods and services — agricultural, industrial or otherwise. Taking root in the late 1990s across a range of disciplines, the concept has since expanded and evolved.

Most people are familiar with the Great 1906 San Francisco Earthquake and are aware of the earthquake risk posed to the Bay Area — and much of California — by the San Andreas Fault. Most people are not aware, however, that a cluster of large earthquakes struck the San Andreas and quite a few nearby faults in the 17th and 18th centuries. That cluster, according to new research, released about the same amount of energy throughout the Bay Area as the 1906 quake. Thus, it appears that the accumulated stress on the region’s faults could be released in a series of moderate to large quakes on satellite faults, rather than a single great event on the San Andreas. But how this information might change the hazard forecast for the Bay Area is uncertain, scientists say.

Valley Fever — a sometimes-fatal infection with no known cure and no vaccine — is caused by a soilborne fungus that thrives in the hot, dry soils of the southwestern U.S., Mexico and Central and South America. However, recent reports of infections far outside the endemic area indicate the fungus is either spreading or becoming active in new areas. The disease is contracted through inhalation of fungal spores, which can be aerosolized by soil disturbances from construction, excavation, gardening and landscaping, as well as natural events like dust storms, earthquakes, landslides and wildfires. Geoscientists working in the field need to take precautions against contracting the disease.

EARTH Magazine: Living in the Shadow of Mauna Loa: A Silent Summit Belies a Volcano's Forgotten Fury
Earth’s largest active volcano, Mauna Loa on Hawaii’s Big Island, is taking a nap. And after 30 years, no one is sure when the sleeping giant will awaken. Scientists say it’s likely to erupt again within the next couple of decades and, when it does, it will be spectacular — and potentially dangerous.

From the delicate geometry of a crystal lattice to the sweeping strata of an anticline, geology is an inherently 3-D discipline. Three-dimensional printing offers the chance to make those structures replicable, communicable and malleable. And it can make objects themselves “open source,” enabling wider access to specimens for students and giving researchers the power to handle and manipulate the natural features they study. Read more about how geoscientists are using 3-D printing to transform their science in the September issue of EARTH Magazine: http://bit.ly/1p1SgX6.

The La Brea tar pits in downtown Los Angeles are a famous predator trap. For every herbivore, a dozen or more carnivores — saber-toothed cats and dire wolves chief among them — are pulled from the prolific Pleistocene fossil site. In fact, the remains of more than 4,000 dire wolves have been excavated, along with more than 2,000 saber-toothed cats. The sheer number of fossils allows researchers to ask population-level questions about the climate and environment as well as how these animals evolved. Now, two new studies focusing dire wolves and saber-toothed cats are characterizing how the tar pits’ two top predators coped with the warming climate toward the end of the last ice age, and the results are surprisingly dissimilar: While the wolves got smaller, the cats got bigger.

Citizen science initiatives invite ordinary citizens to participate in scientific research by making observations and contributing to large data sets. Such projects offer great ways for young people, amateur enthusiasts, and other nonprofessional scientists to become actively involved in the scientific process.

New research examining plate movements under Tokyo has found that since the massive magnitude-9 Tohoku earthquake and tsunami in March 2011, recurrence intervals for nondamaging slow-slip quakes beneath Japan’s capital have shortened. That has left seismologists wondering if this aseismic creep could be signaling a countdown to Tokyo’s next “big one.” Read more about scientists’ estimations of Tokyo’s seismic risk in the August issue of EARTH Magazine.

EARTH Magazine: Unlocking the Cascadia Subduction Zone's Secrets: Peering into Recent Research and Findings
The Cascadia Subduction Zone is a 1,000-kilometer-long subduction zone stretching from Mendocino, Calif., to north of Vancouver Island off the coast of British Columbia, Canada. A real threat is a potentially devastating magnitude-9 earthquake and the potentially ensuing tsunami — which has happened before and will happen again. But when? And what will happen when this massive fault does start shaking? Scientists have been working diligently over the last couple of decades to answer those questions. A series of recent oceanic research cruises and datasets has steadily advanced our understanding of Cascadia, but there is still much to learn.

The last several decades have seen Arctic sea-ice minimums drop by more than half in area and more than three-quarters in volume. With current models predicting further reductions, scientists are calling it the “new normal” and are trying to grasp its implications — one of which is the occurrence of pathogens never before seen in the Arctic.

Tucked high in the Andes Mountains of northern Peru is a remarkable fossil locality: a 39-million-year-old petrified forest preserved in nearly pristine condition: stumps, full trees, leaves and all. With its existence unknown to scientists until the early 1990s — and its significance unbeknownst to villagers — this ancient forest hosts the remains of more than 40 types of trees, some still rooted, that flourished in a lowland tropical forest until they were suddenly buried by a volcanic eruption during the Eocene.
