New underwater video shows cracks in California pipeline

In the video recorded on Monday, which has been annotated with a red circle to show where the pipeline was raptured, oil appeared to no longer be leaking.

Investigators were still searching for what caused the offshore pipeline to rupture.

The U.S. Coast Guard on Wednesday inspected a vessel in Oakland focusing on the possibility that a ship's anchor struck a pipeline, causing an oil spill in California, the Los Angeles Times reported.

Amplify Energy, which owns the pipeline and connected rigs, is under scrutiny about the time it took to respond to the spill.
