Vanish?The examples would be contraventions of natural law - hence supernatural.
Any speculation as to what would happen to the rest of the natural laws is merely that - speculation (and a strawman, since we have no way of knowing what would happen if ANY natural laws were broken).
Strawman again.
Will you not attempt to measure the natural forces, to determine what is going on first?
Perhaps suddenly the acceleration due to gravity changed which can account for the observation.
In order for something to be supernatural it would have to occur when something is NOT explained by natural laws (correct?)- so your natural measurements should be normal but the phenomenon would be abnormal.
Can you observe this 'supernatural' force- no. because the moment it comes into observation it can be incorporated into the 'natural laws' as just another force- specifics of which would be unknown..
Also you would have to assume that this 'supernatural event' is via mechanism where the natural laws are not altered (which otherwise would explain the phenomenon through natural means).... In essence the supernatural force would not change the natural force. As if the natural forces are altered then the phenomenon would be explained by the change in natural forces.
So you're working with the assumption: Supernatural events occur via mechanism where there is no affect on the natural forces. - This assumption of such a mechanism must first be shown not the supernatural itself.
First of all even considering 'supernatural' you have to say that it is an assumption proposed by theists. So we begin our thoughts from the following initial assumption:
The fact (what theists claim) that the 'supernatural' created the 'natural'
This means that the supernatural has an affect on the natural forces, yielding the above assumption that supernatural doesn't change the natural laws in basically a paradox.
So your claim that the supernatural changes an event without utilizing natural laws is bogus and thus so is your definition. Or at least is not defining what theist claim exists.. So your definition of supernatural actually doesn't conform to God- so you're asking for a completely different thing.
Peace be unto you
