"I've seen it bubble up a little bit before, and it's always fascinating when it happens. Thinking, OK, the tar pits are gonna win this time and take over the world," Andrea Ross-Greene said laughing. "This is the biggest eruption I've seen, and I think it's pretty cool."
The earth has been oozing tar and methane gas in the area since pre-historic times.
Eruptions are fairly common in the area, but residents say it's is a relatively large leak that's easy to see and smell.
The city will continue to clear the tar spillage until it hardens, essentially sealing itself off.
