Large earthquakes generally produce ground deformation that can be measured by geodetic instruments. Geophysicists can use these measurements to invert the earthquake source parameters, that is, to recover the earthquake slip on the ruptured fault. However, the conventional inversion of geodetic data does not fully resolve the geometry of the broken fault at depth. Wei ...

Caucete y sus alrededores. Haciendo énfasis en una mirada integral, y sin perder de vista las particularidades que pueden presentar ...

Like the Amazon, Cleethorpes Saltmarsh is a spectacular landscape that supports a rich variety of plants, birds and other creatures. It also captures and stores polluting carbon dioxide – more so than an area of rainforest the same size. North East Lincolnshire Council has created a new immersive story map to tell the remarkable story ...

Lava and smoke shine brightly in a fresh satellite image of an erupting Hawaiian volcano. Kilauea, based on Hawaii’s Big Island nearby the volcano Mauna Loa, has been erupting again since Jan. 5 and its fresh activity glows in a Landsat 8 satellite image taken on Jan. 11. Activity extending from September 2021 to December ...

Con la Legge di Bilancio 2023 sono state assegnate risorse, al Dipartimento per il servizio geologico d’Italia dell’Istituto superiore per la protezione e la ricerca ambientale (ISPRA), per il completamento della Carta geologica d’Italia (CARG). In particolare, è autorizzata a favore del medesimo Istituto la spesa di 6 milioni di euro per ciascuno degli anni ...

Kuwait Oil Company (KOC) is enhancing the quality and accuracy of the data used for daily planning to support production operations and the decision-making process for the implementation of current and future projects. This was done by contracting with one of the international companies specialized in this field. This project, for the first time since ...

Satellite imagery could help paleontologists spot promising fossil sites before trekking into remote places. New research from the lab of UO paleontologist Edward Davis in the Department of Earth Sciences shows that satellite data can reveal large individual fossils from the air, allowing field researchers to embark on more targeted searches on the ground. Their ...

Hexagon’s Safety, Infrastructure & Geospatial division and OSASI Technos Inc. have announced a partnership to deliver next-generation disaster management and monitoring solutions. Using 3D visualization capabilities, governments will be able detect, predict and simulate impending disasters, enabling them to better plan for and respond to impending disasters, enabling them to better plan for and respond ...

The study, ‘Spectral Characteristics of Ionospheric Disturbances Over the Southwestern Pacific From the 15 January 2022 Tonga Eruption and Tsunami,’ explores how evidence from the ionosphere explains why the tsunami grew larger and travelled faster than tsunami forecasts predicted. Due to tsunamis being an extremely rare natural disaster, current tsunami warning systems are far from ...

The Hellenic Survey of Geology and Mineral Exploration (HSGME) is working on a digital map that will provide details on the locations, characteristics and potential seismicity of the country’s fault lines. The database will also be enriched with input from all the other specialized agencies and will be open to the public and not just ...

An international team of researchers has found that an acceleration in movement of a deep landslide beneath the city of Bukavu, in the Democratic Republic of the Congo, is due to city sprawl, not natural forces. In their study, published in the journal Nature Geoscience, the group analyzed satellite imagery and aerial photographs of the ...

Un team di ricercatori dell’ENEA ha sviluppato un nuovo approccio per prevedere l’area di propagazione e l’intensità delle colate rapide, un particolare tipo di frane veloci altamente distruttivo, e sta testando nuove metodologie per stimarne le soglie di innesco in base al contenuto di acqua dei terreni di copertura. Le innovazioni volte al la produzione ...

An analysis of thousands of water and oil wells in the Houston metro area has uncovered significant rates of subsidence, or gradual sinking of the ground, in some of the region’s fast-growing suburbs that have not been previously reported. Shuhab Khan, professor of geology at the University of Houston, led the study published in the ...

The British Geological Survey (BGS) has released a new fine-scale digital map featuring the seabed geology of offshore Anglesey. The island (in Welsh known as Ynys Môn) follows the Bristol Channel as the second in a series of new fine-scale maps that contain combined bedrock, sediment, bedrock structure and seabed geomorphology data. The maps are ...

NASA and the U.S. Geological Survey (USGS) will map portions of the southwest United States for critical minerals using advanced airborne imaging. Hyperspectral data from hundreds of wavelengths of reflected light can provide new information about Earth’s surface and atmosphere to help scientists understand Earth’s geology and biology, as well as the effects of climate ...

أطلق وزير الطاقة والثروة المعدنية، صالح الخرابشة، الاثنين، خريطة تفاعلية لتسويق قطاعي (الثروات المعدنية والتنقيب عن البترول والغاز). وقال الخرابشة، إنّ الخريطة تعرض التوزيع الجغرافي والمعلومات الفنية للفرص الاستثمارية المتاحة في القطاعين، بالإضافة إلى أن الخريطة توفر موقعاً متكاملاً لتوجيه المستثمر في البحث عن خيارات مختلفة في قطاع التعدين توفيرا للجهد والوقت في الوصول إلى ...

thanks to Europe’s environmental Copernicus program and the Sentinel-1 radar satellite mission, the first Europe-wide subsidence and soil movement analysis service is available to the public. The new European Ground Motion Service, the latest offering of the Copernicus Land Monitoring Service and implemented by the European Environment Agency, provides free and accessible ground motion data ...

On 19 March 2021, the volcano Fagradalsfjall began to erupt, suggesting that volcanoes on Iceland’s Reykjanes Peninsula had awakened from an 800-year slumber. Although most volcanism in Iceland occurs in regions far from population centers, eruptions on the Reykjanes Peninsula can threaten residents. Pedersen and a team of scientists came together to create maps to ...
