Coastal landscapes, including sandy beaches and foredunes, are dynamic and susceptible to changes caused by water level fluctuations, storm events, and human activities. Monitoring these changes is crucial for effective coastal management and resilience planning. Traditional methods for measuring geomorphic changes, such as small-unoccupied aircraft systems paired with structure-from-motion photogrammetry (sUAS-SfM), are often costly and ...

The British Antarctic Survey (BAS) has released a new map viewer that brings together all of the Antarctic Digital Database datasets, plus other useful information, and displays them together in an open-access interactive website. The BAS’ Mapping and Geographic Information Centre (MAGIC) is responsible for keeping the maps and data up to date, with the ...

The geology along Ecuador’s Coca River is moving in fast-forward. In a scientific field where natural wonders form over millennia, but natural disasters occur in minutes, speed is less than desirable. Over the last four years, the river and its surrounding area within the Amazon basin have experienced a lava dam collapse, 500 million tons ...

A new map showing the bed of Lake Wānaka in “incredible detail” will help scientists work out the lake’s potential for earthquakes and tsunami, Niwa says. The work was done after an active fault was found under the lake three years ago. Lake Wānaka is thought to be at risk of a tsunami-like event due ...

A team of international scientists involving the Durham University Geography department has unveiled a new map of the geological provinces hidden beneath the Greenland Ice Sheet.

The Australian Government’s Exploring for the Future program is continuing to deliver for the resources industry with the release of a new tool to support the discovery of minerals critical to the net zero transformation. The Heavy Mineral Map of Australia, developed by Geoscience Australia in collaboration with Curtin University, has been created using heavy ...

On Sept. 29, 2009, an 8.1-magnitude earthquake struck near American Samoa, Samoa, and Tonga, triggering a tsunami that caused human casualties and $200 million in property damage on the islands. The earthquake also exacerbated another problem in American Samoa: subsidence, or the sinking of land. When combined with relative sea level rise, land sinking can ...

The U.S. Geological Survey (USGS) has released a compilation of national-scale geological, geophysical and mineral resource datasets from Australia, Canada and the US through a collaboration between the three countries’ federal geological surveys. “Geology doesn’t stop at the border and neither does our data,” said USGS scientist Anne McCafferty, who led the effort. “Scientists will ...

Analysis of Global Positioning System (GPS) time-series data from nearly 100 large earthquakes worldwide has provided evidence for the existence of a precursory phase of fault slip occurring two hours before seismic rupture. “If it can be confirmed that earthquake nucleation often involves an hours-long precursory phase, and the means can be developed to reliably ...

There’s a massive “hole” in the Indian Ocean, researchers say—but it’s not the kind that could drain away all that water. Instead it’s a term geologists use to describe a spot where Earth’s gravity is lower than average. And a new study may have finally revealed its origins: it appears to be caused by plumes ...
