A second earthquake shook Samoa and Tonga this evening, about 11 hours after residents were awoken by a mild tremor in the morning.
The United States Geological Survey said the evening quake had a magnitude of 5.2 and was centered just over 100 kilometres north northeast of Hihifo, Tonga and 220 kilometres southwest of Apia, the capital of Samoa.
Shortly after the evening quake, a small bridge in Leone village in American Samoa collapsed.
There were no cars on the bridge at the time and children who were walking from Leone to Auma village escaped unharmed.
The same bridge was washed away during last years tsunami.
A Leone resident Maiava Fidelis Leota said cars were unable to cross the bridge for several hours.
Crews from Public Works restored one lane late Wednesday night.
