including seven well-built homes with anchor bolts that were swept away.
Vehicles were thrown hundreds of feet
several freight train cars were overturned
and multi-ton oil tanks were destroyed.
Trees were completely denuded and debarked as well.
This was the first tornado to have been rated EF5 after the retirement of the original Fujita Scale in the United States in February 2007.
Winds inside according to velocities were 230 knots (264-265 mph) making it well above the EF5 threshold.
Also a field near town was heavily scoured.

A rebar support set into the foundation of another home was found snapped in half
and reinforced concrete light poles were snapped and dragged along the ground.
A large industrial building was completely destroyed
with metal beams twisted and sheared off at their bases
and the foundation pushed clean of the metal framing and debris.
Vehicles were thrown long distances and stripped down to their frames as well.
Additionally
a large field east of Parkersburg was filled with finely granulated debris that was wind-rowed in long streaks

 |
| (Image 3A)Tornado Crosses the road weakening into a EF2 , after this in reed's vid becomes hidden in the rain and Strengthens into a EF3. |
 |
| (Image 3B)Interestingly It appears you see deep ground scouring just south where it ropes out , looking a year back shows this empty streak wasnt there, its very unclear what happend at this spot. |
 |
| Zooming in to this spot this so call Tree damage is sharp , it appeared to have been bulldoze afterwards. |
 |
| The Severety of this so call damage is much worse then what NOAA says for just EF1 , and extends way longer towards the east , and is south of the so call End path. |
 |
| A spot seen in (Image 2) where EF5 Damage happend , looks very similar to the 2 images above. |

Many homes

A large multi-story hospital had its foundation and underpinning system so severely damaged that it was structurally compromised and had to be torn down.
Reinforced concrete porches were deformed
lifted
and tossed
and 300-pound (136 kg) concrete parking stops anchored with rebar were ripped from parking lots and tossed well over 100 ft (30 m).
Vehicles were thrown several blocks away from the residences where they originated
and a few were never recovered.
Damage to driveways was noted at some residences as well.
A large steel-reinforced concrete "step and floor structure" leading to one building was warped slightly and cracked.
Ground and pavement scouring occurred
and heavy manhole covers were removed from roads as well.
On June 10, 2013
an engineering study found no evidence of EF5 structural damage in Joplin due to the poor quality of construction of many buildings.
However
the EF5 rating stood as the National Weather Service in Springfield, Missouri
stated that survey teams found only a very small area of EF5 structural damage (at and around the hospital) and that it could have easily been missed in the survey
and the EF5 rating was mainly based on large vehicles being thrown long distances
along with non-conventional
non-structural instances of damage
such as removal of manhole covers
pavement
concrete porches
driveways
and parking stops
and the presence of wind-rowed debris.

you realy underestimate the tornado in how long it was on the ground , how the noaa post are seperates the tornado when it crosses counties , if you read closely , example the iowa tornado was separated into 4 segments , each segment is made when it crosses into a new county
Deletehope this helps on how you look at the tornado data c:
Deletewoops I mean 3 segments plus a satellite tornado
