A deep magnitude 6.9 earthquake reduced to a mag 6.8 by USGS has struck about 130 miles (209 km) east-northeast of Tarija, Bolivia early on Monday at a depth of 346 miles (557 km)
It is the 2nd major quake to strike today after a magnitude 6.3 struck in the Pacific Ocean, 427 km southwest Southwest of the Fiji Islands earlier this morning.
The two major quakes struck as a northern coronal hole has opened up on our Sun.
Of the 33 major quakes reported this year, 32 of them have occurred during coronal activity on the sun.
Solar wind flowing from the indicated coronal hole is expected to brush against Earth's magnetic field.
Today's two major quakes were the 9th and 10th of March and brought the total for the year to 33.
