Space weather and geomagnetic activity related to Ecuadorean M7.5 earthquake recorded on February 22, 2019.

On February 22, 2019 at 10:17:23 UTC, an M7.5 earthquake was recorded in Ecuador. The authors, by monitoring in real time solar activity and terrestrial geomagnetic activity, identified a solar wind proton density increase and an increase in terrestrial geomagnetic activity that preceded the Ecuadorian seismic event of 72 hours (respect to solar wind ionic flux) and 48 hours (respect to geomagnetic perturbation). This type of correlation was first observed by the authors in 2011. To date, all destructive seismic events that are recorded on a global scale are always preceded by a solar wind proton density increase. [ABSTRACT FROM AUTHOR]
