History
In 1823, an Augustinian priest, Fr. Bernardo Lago arrived on the town of Pidigan, where he built a church and a rectory atop a hill near the river, marking the official start of Catholicism in Abra.[3]
In 2022, the Abra River Fault, which runs along the river, triggered a magnitude 7.0 earthquake in Abra.[4]
Geography
The Abra originates in the southern section of Mount Data. It descends westward to Cervantes, Ilocos Sur, and flows into Abra. At a point near the municipality of Dolores, it is joined by the Tineg River, which originates in the uplands of Abra.[5] There are also other small rivers like the Binongan River, Ikmin River, and other rivers connecting to Abra River.[6]
