Study reveals anomaly in pre-seismic atmospheric radon associated with inland earthquakes

Previous studies have shown elevated levels of radon in the atmosphere prior to the mainshock of a huge inland earthquake. However, in a new study, researchers revealed an anomaly in this phenomenon as they found that the concentration of the radioactive element...

Study finds correlation between solar activity and large earthquakes worldwide

A new study published in the Nature Scientific Reports on July 13 suggests that powerful eruptions on the Sun can trigger large earthquakes on Earth. In the paper, the authors analyzed 20 years of proton density and velocity data, as recorded by the SOHO satellite,...

Forecasting earthquakes 5 days ahead, research

An international team of scientists reporting in Doklady Earth Sciences discovered that with an impending earthquake, the parameters of internal gravity waves (IGWs) can change several days before the seismic event. IGW is the fluctuation of air masses, which, in...

Groundwater chemistry as a precursor for earthquakes: The Iceland experience

Even during ancient times, our predecessors have used numerous precursor signals for upcoming natural disasters. Groundwater chemistry is one of them and according to latest scientific researches it has been observed to change before earthquakes. Alasdair Skelton from
