The quake comes as Earth's magnetic field is quieting, finally, almost 48 hours after a surprisingly strong geomagnetic storm sparked auroras seen from the Arctic Circle to the continental USA.
August has seen a plethora of major quakes and volcanic activity, unprecedented in my years as a blogger and the quakes keep coming...
According to Spaceweather.com, a strong G3-class geomagnetic storm has been in progress since Aug. 26th as Earth passes through the wake of a CME that arrived with little fanfare as it was unexpected.
Strong magnetic fields in the CME's wake have opened a crack in Earth's magnetosphere, allowing solar wind to enter and causing seismic and volcanic disturbances, (IMHO)
Once again the quakes come as our Earth is inside a stream of solar wind flowing from a massive coronal hole.
Today's major quakes bring the total in August to 22, easily the most in one month this year with the annual total to 72 so far.
Along with the quake activity August has seen an uptick in volcano activity too, the volcano on Papua New Guinea's Manam Island erupted again as well as Mount Etna the most famous and biggest volcano in Europe.
Earlier in the month, Japan's Meteorological Agency said volcanic earthquakes and sulphur emissions had increased at a peak on Kuchinoerabujima island, located roughly 1000km southwest of Tokyo.
Nearly two dozen quakes at the gigantic Katla volcano in Iceland had experts worried this month which is long overdue for an eruption and the deadly Fuego volcano in Guatemala which killed 300 causing thousands to be evacuated two months ago erupted yet again on in early August.
At the beginning of the month, the Karymsky Volcano Kamchatka in eastern Russia exploded plumes of ash spreading almost 100 km
And on the 1st of August Mexican colossus the Popocatepetl volcano spewed ash and smoke two kilometres high threatening 30 million people.
