If a tornado is measured on the Enhanced Fujita by damage, how is a tornado in an open field measured?

Also, could this mean that there are more EF5 tornados in more rural areas that go undocumented?

If a tornado with 300+ MPH winds (that are accurately measured) only snaps a single twig off one tree and doesn’t carve the slightest path in the ground, it’s EF0/1. If a tornado with 80MPH winds toppled a single reinforced structure but then vanished after 2 minutes, its EF5. 

Any tornado that does basically no damage is EF0, even if the **potential** is there. It’s very very very likely that there are dozens of tornadoes every year that have the POTENTIAL to obliterate reinforced concrete structures but happen to occur in open farmland which lands them an EF0 rating.
