Why in news?
A magnitude 5.8 earthquake struck Negros Island in the Philippines on 2 November 2025. Though no major damage was reported, the event drew attention to the geography and hazards of this populous island.
Background
Negros is the fourth‑largest island and the third‑most populous in the Philippine archipelago. Part of the Visayas group, it lies between the islands of Panay to the west and Cebu to the east, separated by the Guimaras and Tanon straits respectively. The island is boot‑shaped, stretching about 217 km long and between 35 and 79 km wide.
Geography and economy
- Mountain spine: A north–south mountain range runs along the island’s length, culminating in Mt Canlaon, an active stratovolcano rising 2,465 m. Lava flows and fertile soils from past eruptions support agriculture.
- Rivers: Several short but fast‑flowing rivers, such as the Binalbagan and Ilog, drain westward across the plains before emptying into the Sulu Sea.
- Provinces and people: Negros is divided into two provinces—Negros Occidental in the west and Negros Oriental in the east—with major cities including Bacolod and Dumaguete. It is a hub of the Philippine sugar industry.
Significance
- Hazard awareness: The island lies in a seismically active region; the recent quake underscores the need for resilient infrastructure and disaster preparedness.
- Economic importance: Sugarcane plantations and fisheries are major employers; disruptions from natural disasters can affect livelihoods.
