LOS ANGELES (CBS) — Debris from last year’s deadly tsunami in Japan is washing ashore on the West Coast — and some of it may even contain human remains.

Officials are warning the public to not touch the debris.

Items as small as clothing and as large as a dock and a fishing boat have been reported washing up along the West Coast.

Heal The Bay started surveying Malibu and Palos Verdes and said they have not found any items from the disaster.

Los Angeles City officials asked L.A. Port leaders Friday to outline how they plan to handle the items washed ashore.

Authorities ask that residents to contact them if you find debris, especially any mementos so they can try to return them to their original owners in Japan.
