Clean up efforts continued Monday in the Santa Cruz harbor as city officials and environmental experts dealt with the impact of Friday's tsunami.
Officials list the damage estimate at more than $17 million after a series of tsunamis hit the harbor knocking boats and docks off their moorings.
On Monday engineers brought in sonar to help scour the bottom of the harbor for sunken vessels that are still missing. There are as many as 12 of them down there and each pose an oil spill in the waiting, according to the Coast Guard.
About 100 other boats received damage ranging from broken masts to dings, according to harbor officials. The harbor was officially closed all weekend which meant the people who live on their boats had to find another home.
The area became a tourist destination over the weekend as people from the Monterey Bay area and San Jose came to access the damage for themselves. The area, which is often bustling thanks to popular restaurants like Aldo's and the Crow's Nest, was hard to reach this past weekend thanks to the added crowds and street closures.
