A three-dimensional box that mimics an underwater ocean scene teaches players about an underwater fossil fuel resource in a new Japanese board game. Methane hydrate is a natural energy resource buried deep below the ocean floor surrounding Japan. This mixture of methane and ice, once extracted, can be converted into methane gas, a viable energy source. Chiharu Aoyama, an ocean resources professor at the Tokyo University of Marine Science and Technology, suspects Japan’s citizens do not know about this natural resource. In 2016, Aoyama worked with Daiki Aoyama, a family member and game hobbyist, to design a board game to raise awareness about methane hydrate among Japanese people of all ages.

On December 9, several Australians were among the dozens of tourists who were killed, injured, or went missing after a deadly eruption on Whakaari/White Island in New Zealand. Whakaari/White Island has seen more volcanic activity in the past 10 years than neighboring Australia has seen for 5,000, but according to volcanologists, the country is not free from the risks of a potential eruption. And according to a new survey, Australian citizens are mostly unaware of their country’s potential volcanic hazards.

An Apollo 16 lunar rock sample shows evidence of intense meteorite bombardment on the Moon 4.3 billion years ago, according to new research. The results provide new insights for the Moon’s early history, showing lunar impacts were common throughout the Moon’s formation than previously thought.

A geologic fault system in central Italy that produced a deadly earthquake in 2016 is also responsible for a fifth-century earthquake that damaged many Roman monuments, including the Colosseum, according to new research. The Mount Vettore fault system, which winds through Italy’s Apennine Mountains, ruptured in the middle of the night on August 24, 2016. The magnitude 6.2 earthquake it generated killed nearly 300 people and destroyed several villages in the surrounding region. The fault ruptured again in October 2016, producing two more earthquakes with magnitudes greater than 6.

Some of the remnant walls snaking through the forests of New York and New England from long-abandoned early American farms can be used as references to deduce the position of Earth’s magnetic field in previous centuries.

By Joshua Rapp Learn Whether they are found in an engagement ring or an antique necklace, diamonds usually generate quick reactions from their recipients. Now, new research shows deep inside the Earth, fast reactions between subducted tectonic plates and the mantle at specific depths may be responsible for generating the most valuable diamonds. The diamonds mined most often around the world are formed in the Earth’s mantle at depths of …

Scientists have developed an automated early warning system for volcanic eruptions, according to a new study. The new system helped government officials warn the public of impending eruptions in Italy and could potentially do the same around the globe, according to the study’s authors. The new research details the new system that monitors volcanic noises and automatically alerts officials if an eruption is imminent. The study’s authors tested this system over a period of eight years on Mount Etna, a volcano on the island of Sicily. Using the new system, the Italian government activated an emergency plan about one hour prior to an eruption for the first time in late 2015.

In 2017, Evgeny Podolskiy spent more than a week trekking through the Nepalese Himalayas to test the seismic activity of the Trakarding-Trambau Glacier system. In October, the research team and a group of sherpas and porters traveled to an open, debris-free glacier about five kilometers (3.1 miles) above sea level, in full view of Mount Everest.

Scientists have discovered hundreds of crescent-shaped pits on Mars where sand dunes stood billions of years ago. The curves of these ancient dune impressions record the direction of prevailing winds on the Red Planet, providing potential clues to Mars’s past climate, and may hold evidence of ancient life.
