JAKARTA, June 16 (Xinhua) -- Tidal waves striking Indonesia's Bali island have left one holiday maker dead and another injured, a senior official of disaster agency said here on Thursday.

Piter Tan and Wong Sum Sum, both 64 years old from China's Hong Kong, were dragged to sea by tidal waves in a popular surf spot in Sanur beach of Bali, Gde Jaye, senior official of the agency said.

"Peter Tan was dead, but Wong Sum Sum survived after being treated at Sanglah Hospital," he told Xinhua by phone from Bali.

Several cafes and restaurants have been damaged by the unusual and dangerous huge waves in Jembrana tourist resort, Jaye disclosed.

Tourists in Bali have been warned to stay alert as the meteorology and geophysics agency forecast the extreme weather will keep happening until the end of this month.

"Coast guards have boosted surveillance in beaches at several spots. Tourists are also warned and banned from beach activities," the official stressed.

Previously, hundreds of houses and building were damaged on Java Island and hundreds of people fled homes after tidal waves and sea water flooding hit coastal areas, according to the national disaster management agency.
