A massive fire sent flames shooting through the branches of a large, tall tree in Seattle’s University District late Tuesday afternoon.

The fire reportedly began at a homeless encampment near NE 50th Street and 9th Avenue NE. It was spotted around 4:30 p.m. Thick black smoke could be seen from I-5.

Ten units were dispatched to the scene. No injuries were reported. Siding on a building adjacent to the blaze was melted. It is unclear how the fire began.

Video posted by KIRO 7’s Joanna Small shows a blaze burning through the large tree, with items exploding underneath.
