Correlation between Tornado and Seismic activity

Many of you have seen the devastating effects of a large tornado outbreak in Ill and Ind Feb 28- Mar 3 of this year. Here is a nice compact presentation of some data gathered from seismographes by scientists at Indiana university.

It begs the general question are atmospheric and seismic phenomenon related?

Will it provide future results this spring?

Okay rather than waste and edit and make a new post, let me try and rephrase the question. Are they thinking that the atmospheric pressure changes that occur in conjunction with very strong tornadoes can actually deform the crust enough to cause mild seismic activity? I can see how that could make sense.

It is not science to take one incident and make any kind of correlation. Bit premature.

Researchers are not claiming the tornado itself was the direct reason the seismographs detected activity. Instead, they are analyzing the correlation of the atmospheric pressure prior to the tornado. There are some indices that show seismic activity prior to a tornado forming and hitting the ground. During the February 29 event, scientists found a slow and small tilting of the seismograph that lasted for several minutes. Hamburger called it a pressure-related signal and said it might help scientists better understand atmospheric activity that takes place right before tornadoes touch down.

from your link. It would have to be consistent over time and in many locals for it to be relevant.
It is interesting, but misleading.
