I’ve been watching it live on the news (I live in NC) and it looks like a targeted hit to me. Just my opinion, no sauce. But this is not something that is a common occurrence around here.
According to a commentor on WRAL, they felt their house shake in Chapel Hill. I don’t think a simple gas leak would do that.
General area. People mistakenly think Raleigh Durham and Chapel Hill are all a part of the RTP and they are not. These cities span many miles and 3 counties.
It was being reported on WRAL that it was a coffee shop that had been closed. I live in NC, an hour or so away from Durham and I’d be happy to dig.
