Солтүстік Самар провинциясының Сан-Антонио муниципалитеті

Municipality in Northern Samar, Philippines

San Antonio, officially the Municipality of San Antonio (; ; ), is a 5th class municipality in the province of Northern Samar, Philippines. According to the 2020 census, it has a population of 8,882 people. Its territory is coterminous with Dalupiri Island, just off the western coast of Samar Island at the south end of the San Bernardino Strait. The island's white beaches are considered an "undisturbed paradise" and future "premier tourist destination" in the Eastern Visayas region. San Antonio is also unique, as it is the only municipality in Northern Samar that also speaks Cebuano due to the influx of Boholano and Cebuano settlers in the past. The locals speak Waray which is the predominant language of Northern Samar and it is the main lingua franca in the island.

In the early 19th century the settlers from the mainland of Samar found the island an ideal ground for fishing and bird hunting. They come to the island just to catch fish and hunt birds and go back to the mainland of Samar after a handful of catch. People from Bohol and Cebu came to the island in the second half of the 19th century and introduced a method of catching fish using net, commonly known as "laya". With its introduction, the name "Manoglaya" was born, which literally means mano nga paraglaya or "fishermen using laya". As new settlers came and built new communities in the island, they called the island as "Sugod sugod", a Cebuano derivative meaning "just to start or begin". Later, name was changed to "Matabia", referring to the knife shape of the island. No one knows now why it was changed that way, neither folklores nor historical data reveal the ways and wherefore of the change of its name to Dalupiri Island. In 1904, the Municipality of San Antonio of the province of Samar in Dalupiri Island was established. The Municipality of San Antonio named after its patron saint Anthony of Padua.

Dalupiri Island lies in the east central periphery of the Philippine archipelago. It is bounded by San Bernardino Strait in the north and east, Samar Sea in the south, and Capul Island in west. It is approximately 5 nautical miles from the Pacific Ocean and sits near the entrance along the Paso de Acapulco, otherwise known as San Bernardino Strait. It has long white sand beach around the island. Dalupiri Island is a 2,700 hectare island of gently rolling hills, mostly of coconut vegetation and shrubbery. It is home to white beaches, caves, and the Lagbangan Lake.

The island is composed largely of low and extremely rugged hills and small lowland areas. The island is endowed with relatively rich and fertile soil that allow most crops to be cultivated, but presently it is utilized mostly for coconut plantations. The highest point of the island is in its central southern portion with a maximum elevation of above sea level.

The island has no distinct dry or wet season but it has pronounced rainfall from October to January. The heaviest precipitation occurs in November. May is relatively the driest month.

San Antonio is one of the manufacturing centers of dynamite chemicals like ammonium nitrate, used in the manufacture of blasting caps that are sold in the other provinces of Samar island. It was learned that the island has been tagged by the police as one of the areas in the manufacture of the dynamite blasting caps. Chief Supt. Abner Cabalquinto, Regional VIII Police Director, disclosed that the police operatives in Northern Samar confiscated 50 bags of ammonium nitrate in the town of San Antonio. However, the suspects were able to escape and alluded arrest by the police. Because of the prevalence of homemade dynamite, blast fishing is a perennial problem in the region. In 1994, an Italian tourist was killed and another severely injured while diving when a local fisherman dropped his dynamite on top of them. As a result, the Flying Dog Beach Resort, established in the early 1990s, decided to cease its operation. The Dalupiri Ocean Power Plant is a proposed tidal fence generating station across the Dalupiri Passage between the islands of Dalupiri and Samar.

Because of Dalupiri Island's pristine white sand beach, Republic Act No. 9458 declared San Antonio, together with the island towns of Biri, Capul, and San Vicente, as eco tourism zones in May 2007. With its coral reefs, Dalupiri island is ideal for scuba diving, snorkeling, sailing, yachting, jet skiing, para sailing and marine life observation.

A cultural tourism festival held in the town of San Antonio from the 9th to the 12th of June annually, celebrating the fishing skills of the townfolks. The festival composed of cultural performances, street dance, beauty search and exhibit complemented with “sugod sugod sa plaza”, a nightly entertainment of music and other performances from leading local performers in the community.
