Lying directly on the Marikina fault line, Bagong Silangan is considered as a high risk area for earthquake.Bagong Silangan shares its history with San Mateo, Rizal as it was once part of the municipality until it was ceded to Quezon City in the 1930s.The casualties brought by the tropical storm Ondoy have caused several families to relocate in Batangas and Laguna, thus decreasing the population especially in flood-affected areas.[4] With the predominantly Catholic population, Bagong Silangan hosts cultural events that are heavily themed by their religion such as fiestas that are celebrated every May to give homage to their patron San Isidro Labrador.[4] The barangay is also the home to informal settlers who occupy not only vast tracts of public and private lands but also riverbanks, creeksides, aqueducts and transmission lines.
