Heavy swells have been rolling through the port and marinas of the Mexico's Baja California resort of Cabo San Lucas. Some are several feet (more than a meter) high, but no damage has been reported.
The Mexican navy says it had detected offshore swells of 70 centimeters (2 1/3 feet) related to the tsunami spawned by an 8.9-magnitude earthquake in Japan.
The swells appeared at least twice that high as they rocked boats in the harbor, but they have not topped the seawalls at marinas in Los Cabos.
Mexico earlier closed the cargo port of Manzanillo and officials say some ships have delayed entering ports to avoid possible problems.
