Columbia County 36 inch gas line rupture. Is three a trend?

Yesterday I reported on a gas explosion in Allentown Pennsylvania. The total of damaged houses there is now up to 47.

Today a thirty-six inch gas line ruptured near Hanoverton Ohio. The gas pipeline explosion rocked entire county of Columbiana, reports say it was felt as far away as Pittsburgh PA.

Fox8 News has video of the event.

We now have three major gas explosions in less than 30 days. I don't like this trend. Will my neighborhood be next? Maybe yours?

Are we looking at a systemic failure of technology?
