The Richter scale measures siesmic activity - i.e. earthquakes - not Hurricanes. Hurricane Katrina was a category 5 on the Saffir-Simpson scale.

Hurricane Katrina was nearly 40 miles wide in some places. It was also one of the most destructive storms of all time, and did over 100 billion dollars in damage.
Estimated wave height: 10 meters. Earthquake Richter scale: 8.9
the biggest earthquake recorded was 9.1 on the Richter scale.
The Richter scale is for earthquakes, not tornadoes. Tornadoes are rated on the Enhanced Fujita scale. The largest tornado ever recorded was the 2.6 mile wide monster that hit near El Reno, Oklahoma in 2013. However, size does not necessarily correspond to a tornado's rating. Ratings are based on the severity of the damage a tornado inflicts. The El Reno tornado was officially rated EF3 but there are some indicators that it may have reached EF5 intensity, the highest rating possible.
Katrina
one was new Orleans
Louisiana, Mississippi and Alabama
Very big. It had a magnitude of 8.3 on the Richter scale.
Concerning that the highest reading is 7, so a 6.3 Richter can cause very big damage

Category 1
Magmatic quakes (on the Richter scale, 6-10) are indeed severe quakes. The severity is caused by how large the movement of an earthquake is. If it is a timy move, it may be a 1-5 rank on a Richter scale. For the big movements, you never know how large scientists record it as. The maximum on a Richter scale is 10.
Its because of the amplitude shown on a seismograph according to the Richter scale.
Estimated wave height: 10 meters. Earthquake Richter scale: 8.9
up to at least 8 average 9.5 was the biggest
The evacuation for Hurricane Rita was much more efficient than Hurricane Katrina. The big difference is that the governors in the states involved ordered mandatory evacuations. There were some deaths from heat problems.
