Early Earth may have been a ‘waterworld’
Kevin Costner, eat your heart out. New research shows that the early Earth, home to some of our planet’s first lifeforms, may have been a real-life “waterworld”– without a continent in sight. The study, which appears March 2 in Nature…

The seismicity of Mars
On 26 November 2018, the NASA InSight lander successfully set down on Mars in the Elysium Planitia region.
How earthquakes deform gravity
Lightning – one, two, three – and thunder. For centuries, people have estimated the distance of a thunderstorm from the time between lightning and thunder.
Earthquakes disrupt sperm whales’ ability to find food, study finds
Otago scientists studying sperm whales off the coast of Kaik?ura have discovered earthquakes affect their ability to find food for at least a year. The University of Otago-led research is the first to examine the impact of a large earthquake…

Pre-eruption seismograms recovered for 1980 Mount St. Helens event
Nearly 40 years ago, analog data tapes faithfully recorded intense seismic activity in the two months before the historic eruption of Mount St. Helens in Washington State in May 1980. It took some lengthy and careful restoration efforts–including a turn…

Upper-plate earthquakes caused uplift along New Zealand’s Northern Hikurangi Margin
Earthquakes along a complex series of faults in the upper plate of New Zealand’s northern Hikurangi Subduction Margin were responsible for coastal uplift in the region, according to a new evaluation of local marine terraces. The findings, reported in the…

Signals from inside the Earth: Borexino experiment releases new data on geoneutrinos
Scientists involved in the Borexino collaboration have presented new results for the measurement of neutrinos originating from the interior of the Earth. The elusive “ghost particles” rarely interact with matter, making their detection difficult. With this update, the researchers have…
Earthquake catalog shows complex rupturing during 2019 ridgecrest sequence
The 2019 Ridgecrest earthquake sequence, which startled nearby California residents over the 4 July holiday with magnitude 6.4 and magnitude 7.1 earthquakes, included 34,091 earthquakes overall, detailed in a high-resolution catalog created for the sequence. The catalog, developed by David…

New dinosaur discovered in China shows dinosaurs grew up differently from birds
San Diego Natural History Museum paleontologist describes a dinosaur that is new to science, offers view into dinosaur-bird evolution
Slow-motion interplate slip detected in the Nankai Trough near Japan
Tokyo, Japan–Earthquakes are generally thought of as abrupt, violent events that last for only moments. However, movement of the Earth’s tectonic plates is often less sudden and more sustained – slow earthquakes can last for hours, months, or even longer.…
