While the Costa Blanca refers to the coastline from Denia to Alicante, Torrevieja and Torre Horadada, is meant by Vega Baja del Segura administrative district of the Spanish province of Alicante in the Valencia region. The Vega Baja del Segura includes 27 municipalities, located in the extreme south of the province of Alicante and is adjacent to the region of Murcia, whose capital is Orihuela.
After the town of Orihuela inland, Torrevieja is the main town of this district on the coast. The river Segura flows through this region.
Largest cities and towns are: Guardamar del Segura, San Fulgencio, Dolores, Catral, San Isidro, Albatera, Almordi, Rojales, Formentera del Segura, Benijófar, Los Montesinos, Torrevieja, Cox, Granja de Rocamora, Redovan, Jacarilla, Daya, Rafal, San Miguel de Salinas, Orihuela, Bigastro and Pilar de la Horadada.
The Vega Baja is prone to earthquakes, as European and African tectonic plates meet here. In 1829 an earthquake destroyed more than 2,000 buildings, which today due to the modern and earthquake-proof construction can no longer happen.
