Yes there have been a large number of magnetic reversal with the last one about 780k years ago and we are overdue.
This could be a reversal or magnetic excursion and seems to be related to a cyclical event happening every 12-16,000 years. The magnetic excursion and weakening results in altering poles even multiple poles moving about the planet. All this by itself is not that damaging to our global civilizations but would be quite disruptive to our already changing climate and ecology. However the planet becomes much more susceptible to solar flaring events solar and cosmic radiation resulting in geomagnetic and electric plasma events, related climate, geological and volcanic events. There is building evidence that the Sun can micronova or superflare that may be related to this excursion and results in more severe effects on the planet. We also know that the Sun activity is changing and starting to go into a grand solar minimum.
These excursions have been recorded as
Gothenburg event 10-13k years ago
Mono lake / lake Mungo. 23-35k years ago
Laschamp event 41-45 k years ago
Vostok core event 60 k years ago
I suggest you look at the evidence at the suspiciousobservers.org cosmic disaster. The book of revelations appears to describe these events as well as many cultures around the world.
