Over the last day, the US Geological Survey (USGS) has detected 16 moderate tremors, all stronger than 2.5 in magnitude, in the vicinity of Tonopah Test Range in Nevada, better known as'Area 52.' Both Area 52 and its more famous neighbor, Area 51, sit on a massive complex just north of Las Vegas called the Nevada Test and Training Range (NTTR). For decades, it has been believed that the US military has carried out experimental aircraft testing as well as nuclear weapons research in this remote area. Now, scientists have monitored over 100 seismic events within 50 miles of the Tonopah Test Range in just the last week.


Scientists discover ominous sign that Yellowstone's supervolcano is building up to an eruption

Daily Mail - Science & tech

Scientists have discovered an ominous sign which could hint that Yellowstone's supervolcano is building up to an eruption. Using machine learning, researchers found there have been over 86,000 hidden earthquakes between 2008 and 2022. That is 10 times more tremors than scientists had previously detected. Worryingly, more than half of those earthquakes came in swarms - small groups of interconnected tremors - which have been known to precede volcanic activity. The researchers say these'chaotic' swarms were found moving along rough, young fault lines running deep below the Yellowstone Caldera. These clusters of seismic activity are likely caused by hot, mineral-rich water forcing itself through cracks in the rock.


Can We Achieve Early Earthquake Prediction And Warning?

#artificialintelligence

Earthquakes claimed thousands of lives every decade. Of all-natural calamities, earthquake is the one which is most hard to predict. Even if a man succeeded in doing so, his predictions are vaguely based on the behavior of animals' minutes before the seismic waves hit that geographic region. However, with artificial intelligence algorithms can help us in receiving early warnings of a potential earthquake and be prepared accordingly. Using machine-learning models, seismologists can analyze hordes data on thousands of earthquakes.


California's earthquake 'swarm' triggered by fluid, scientists say

Daily Mail - Science & tech

A strange'swarm' of small earthquakes in California that lasted nearly four years was triggered by fluid spilling into the fault system from underground reservoirs, scientists say. The naturally occurring injection of underground fluid drove the earthquake swarm near Cahuilla in Southern California, which occurred in bursts around the region from early 2016 to late 2019. US scientists have made their conclusions based on earthquake detection algorithms that catalogued more than 22,000 individual seismic events that made up the'swarm'. Using machine learning to plot the location, depth and size of the tremors, the researchers generated a 3D representation of the underlying fault zone. The results suggested dynamic pressure changes from natural fluid injections deep below the surface largely controlled the prolonged evolution of the Cahuilla swarm.


3D fault architecture controls the dynamism of earthquake swarms

Science

The vibrant evolutionary patterns made by earthquake swarms are incompatible with standard, effectively two-dimensional (2D) models for general fault architecture. We infer that fluids are naturally injected into the fault zone from below and diffuse through strike-parallel channels while triggering earthquakes. A permeability barrier initially limits up-dip swarm migration but ultimately is circumvented. This enables fluid migration within a shallower section of the fault with fundamentally different mechanical properties. Our observations provide high-resolution constraints on the processes by which swarms initiate, grow, and arrest.
