Earthquakes follow a well-known power-law size relation, with smaller events occurring much more often than larger events. Earthquake catalogs are thus dominated by small earthquakes, yet still missing a much larger number of even... more

The origin of so-called Kiruna-type apatite-iron oxide ores has been the topic of a longstanding debate for over 100 years. In a new article published in Nature Communications, a team... more
Global warming is significantly reducing the volume of ice sheets—like the one covering Greenland—through melting or by shearing away blocks of ice that tumble into the ocean and become icebergs, a process known as calving. more
Researchers from the National University of science and technology MISIS (NUST MISIS, Moscow, Russia) and the National Institute for Nuclear Physics (INFN, Naples, Italy) have developed... more

Massey volcanologists have discovered the driving force behind superheated gas-and-ash clouds from volcanic eruptions, which may help save lives and infrastructure around the globe. more
Highly localized and accurate Great Lakes ice cover forecasts have been demonstrated by researchers at the University of Michigan, and their predictive modeling tool can be adapted for... more
Metallic asteroids are thought to have started out as blobs of molten iron floating in space. As if that's not strange enough, scientists now think that as the metal cooled and solidified,... more
Scientists have completed the most detailed map yet of one of North America's most spectacular geologic faults with the hope of providing a better understanding of the earthquake risk at... more
Two moderate-sized earthquakes that struck the southern Sichuan Province of China last December and January were probably caused by nearby fracking operations, according to a new study. more

Scientists re-inspected 45-year-old Helios data, finding long trains of massive blobs -- like lava lamp's otherworldly bubbles, but 50 to 500 times the size of Earth -- that ooze from... more
Are prisoners who go back to their old neighborhoods upon release more or less likely to get arrested again than those who move? That's the question... more
Data produced by Internet users can help to speed up the detection of earthquakes. An international team of scientists has presented a method to combine in real time data from seismic networks with information derived from users looking... more
There have been no major ground rupturing earthquakes along California's three highest slip rate faults in the past 100 years. A new study concludes that this current 'hiatus' has no precedent in... more
Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly... more
Overexploitation is one of the main threats to biodiversity, but the intensity of this threat varies geographically. We identified global concentrations, on land and at sea, of 4543 species threatened... more
More than half of the world’s population now live in cities, which are known to be heat islands. While daytime urban heat islands (UHIs) are traditionally thought to be the consequence of less evaporative cooling in... more
In many cases, it takes several minutes after an earthquake to publish online a seismic location with confidence. Via monitoring for specific types of increased website, app, or Twitter usage, crowdsourced detection of seismic activity can... more
Data produced by internet users can help to speed up the detection of earthquakes. Fast and accurate information is essential in the case of earthquakes: Epicentre location, depth and magnitude are minimum requirements to reliably estimate their possibly... more
While exploring hydrothermal vent and cold seep environments, Dr. Mandy Joye (University of Georgia), and her interdisciplinary research team discovered large venting mineral towers that reach up to... more
