Assessing changes in subsidence rates in the low Pampanga river basin and Manila area, Philippines (2021-04-30)

QR code

Activation date: 2021-04-30

Event type: Mass movement

Activation reason:

The service was activated by a request from the Federal Office of Civil Protection and Disaster Assistance (BBK) on behalf of Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) – authorized user, and the University of Philippines – local user. Several sources suggest that the Manila NCR and lower Pampanga river basin, Philippines, has been affected by ground subsidence phenomena impacting settlements and increasing flood risk.The EMS service aims to provide evidence of ground motion patterns in the targeted areas using multi-temporal satellite SAR data analysis – by persistent scatterers interferometry. Product derived from time series of Sentinel-1 imagery provides insight into localization and extent of sinking zones and severity of phenomena related to estimated motion velocity or different adversary patterns.The ground motion map shows average annual vertical and horizontal ground motion velocities. Furthermore, the vector product provides value-adding features such as temporally coherent targets, comparing annual motion trends and classification of motion dynamics such as motion acceleration.
