Diamonds hitch a ride to the surface through explosive kimberlite eruptions, powered by volatile-rich magmas. New simulations show that carbon dioxide and water are the secret ingredients that make these eruptions possible.
Read moreA team at RMIT University has created a cement-free construction material using only cardboard, soil, and water. Strong enough for low-rise buildings, it reduces emissions, costs, and waste compared to concrete. The lightweight, on-site process makes it ideal for remote areas, while its thermal properties naturally cool buildings. Researchers see it as a key step toward greener, more resilient architecture.
Read moreMIT scientists have unraveled the hidden energy balance of earthquakes by recreating them in the lab. Their findings show that while only a sliver of energy goes into the shaking we feel on the surface, the overwhelming majority is released as heat—sometimes hot enough to melt surrounding rock in an instant.

Read moreTypical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends through the highly developed downtown.

Read moreAutonomous drone cameras have been trialled for several years to detect signs of life in disaster zones. Now, in a world first study, researchers have taken this a step further.
Read moreImagine you're getting ready to fly to your favorite vacation destination when suddenly a volcano erupts, sending massive amounts of volcanic ash into the atmosphere, and forcing the cancellation of your flight. That's exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for 6 days. Scientists are now using plasma physics to predict the characteristics of these hazardous ash plumes.
