Seal 6 opening moves every mountain on the planet out of its place so it's not just a strong earthquake--it would have to be something like an asteroid or pole shift. I don't know much about this subject, but given what I know about the Bible and what this man says, it may be very close. The creator of the video says there are only 8 miles to go before it happens. Some in the comments said a days, some a month, and some 2-5 years. Again, I don't know, but it's good to be aware from those who do.
