EUGENE, Ore. (AP) — A series of explosions has gone off in an underground tunnel at the University of Oregon in Eugene, but no injuries have been reported.
Campus officials say the blasts Monday morning appear related to the electrical system, but they don't yet know the cause.
Campus police spokesman Kelly McIver says there were about five explosions around 10 a.m., followed by a series of blasts for about half an hour. Videos showed puffs of smoke coming from manhole covers.
McIver says fire department personnel were waiting to make sure the power has been shut off before going into an underground tunnel to check the electrical system.
The student health center was evacuated, and McIver said a few buildings are either without power, or have power intermittently.
