Catanduanes in the context of "Virac, Catanduanes"

The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago and the largest sea in the world, occupying an estimated surface area of 5 million square kilometers (2×10^ sq mi). The Philippine Sea Plate forms the floor of the sea. Its western border is the first island chain to the west, comprising the Ryukyu Islands in the northwest and Taiwan in the west. Its southwestern border comprises the Philippine islands of Luzon, Catanduanes, Samar, Leyte, and Mindanao. Its northern border comprises the Japanese islands of Honshu, Shikoku and Kyūshū. Its eastern border is the second island chain to the east, comprising the Bonin Islands and Iwo Jima in the northeast, the Mariana Islands (including Guam, Saipan, and Tinian) in the due east, and Halmahera, Palau, Yap and Ulithi (of the Caroline Islands) in the southeast. Its southern border is Indonesia's Morotai Island.

The sea has a complex and diverse undersea relief. The floor is formed into a structural basin by a series of geologic faults and fracture zones. Island arcs, which are actually extended ridges protruding above the ocean surface due to plate tectonic activity in the area, enclose the Philippine Sea to the north, east and south. The Philippine archipelago, Ryukyu Islands, and the Marianas are examples. Another prominent feature of the Philippine Sea is the presence of deep sea trenches, among them the Philippine Trench and the Mariana Trench, containing the deepest point on the planet.

Luzon (/luːˈzɒn/ loo-ZON, Tagalog: [luˈson]) is the largest and most populous island in the Philippines. Located in the northern portion of the Philippine archipelago, it is the economic and political center of the nation, being home to the country's capital city, Manila, as well as Quezon City, the country's most populous city. With a population of 64.3 million as of 2024, it contains 55% of the country's total population and is the 4th most populous island in the world. It is the 15th largest island in the world by land area.

Luzon may also refer to one of the three primary island groups in the country. In this usage, it includes the Luzon Mainland, the Batanes and Babuyan groups of islands to the north, Polillo Islands to the east, and the outlying islands of Catanduanes, Marinduque and Mindoro, among others, to the south. The islands and provinces of Masbate, Palawan and Romblon are also included, although these three are sometimes grouped with another of the island groups, the Visayas.

Central Bikol, commonly called Bikol Naga or simply Bikol, is an Austronesian language spoken by the Bicolanos, primarily in the Bicol Region of southern Luzon, Philippines. It is spoken in the northern and western part of Camarines Sur, the second congressional district of Camarines Norte, the eastern part of Albay, the northeastern part of Sorsogon, San Pascual town in Masbate, and the southwestern part of Catanduanes. Central Bikol speakers can be found in all provinces of Bicol, and it is a majority language in Camarines Sur. The standard sprachraum form is based on the Canaman dialect. The language has also speakers outside their native regional homeland, especially in Metro Manila, Mindoro, Palawan, and Mindanao (particularly in Mati, Davao Oriental)

Central Bikol features some vocabulary not found in other Bikol languages nor in other members of the Central Philippine language family like Tagalog and Cebuano. Examples are the words matua and bitis, which are the same as the Kapampangan words meaning 'older' and 'foot, feet', respectively. The word banggi ('night') is another example of this as it is different from the usual Bikol word gab-i but closer to the word bengi of Kapampangan. There is no formal study on the relationship of the Central Luzon languages to Central Bikol but the latter has several words that are also found in the archaic form of Tagalog spoken in the Rizal and Quezon provinces that are believed to be the home of Central Luzon languages such as Kapampangan in Pampanga and southern Tarlac, and Sambalic languages in Zambales province.

The Bikol languages or Bicolano languages are a group of Central Philippine languages spoken mostly in the Bicol Peninsula in the southeastern part of Luzon, the neighboring island-province of Catanduanes, and the island of Burias in Masbate.

The Bicol Region, designated as Region V, is an administrative region of the Philippines. It comprises six provinces, four on the Bicol Peninsula (the southeastern end of Luzon): Albay, Camarines Norte, Camarines Sur, and Sorsogon, and two off the shore: Catanduanes and Masbate.

The regional center is Legazpi, the most populous city in the region and has one independent component city, the pilgrim city of Naga. The region is bounded by Lamon Bay to the north, the Philippine Sea to the east, and the Sibuyan Sea and Ragay Gulf to the west. The northernmost provinces, Camarines Norte and Camarines Sur, are bordered to the west by the province of Quezon in the Calabarzon region.

Camarines Sur (Central Bikol: Habagatan na Camarines; Tagalog: Timog Camarines), officially the Province of Camarines Sur (Bikol: Probinsya kan Habagatan na Camarines; Tagalog: Lalawigan ng Timog Camarines), is a province in the Philippines located in the Bicol Region on Luzon. Its capital is Pili and the province borders Camarines Norte and Quezon to the northwest, and Albay to the south. To the east lies the island province of Catanduanes across the Maqueda Channel.

Camarines Sur is the largest among the six provinces in the Bicol Region both by population and land area. Its territory includes two cities: Naga, the most-populous, lone chartered and independent city, as the province's religious, cultural, financial, commercial, industrial and business center; and Iriga, a component city, as the center of the Rinconada area and Riŋkonāda Language. Within the province lies Lake Buhi, where the smallest commercially harvested fish, the sinarapan (Mistichthys luzonensis), can be found. The province is also home to the critically endangered Isarog Agta language, one of the three critically endangered languages in the Philippines according to UNESCO. The province is home to historic churches and landmarks reflecting its Spanish colonial past. The Peñafrancia Festival held every September is a significant religious event attracting thousands of pilgrims. The province is also home to indigenous communities such as the Agta whose traditions contribute to the region's unique cultural tapestry

The Maqueda Channel is a strait in the Philippines, eastern side, separating the island of Catanduanes from the Caramoan Peninsula in the Bicol Region of Luzon. The strait connects Lagonoy Gulf and the Philippine Sea.
