“…It was established by Philippine Institute of Volcanology and Seismology (PHIVOLCS), but data collection was done through scheduled survey campaign. The potential of satellite altimetry, tide gauge and GNSS data for VLM determination were demonstrated in several studies (Fenoglio-Marc et al 2004, 2012Avsar, et al 2017;Kleinherenbrink et al 2018;Wöppelmann and Marcos 2015;Ray et al 2010;Nerem and Mitchum 2002;Kuo et al 2008;Zulkifli et al 2018;Yildiz et al 2013) with encouraging results. VLM detection is based on the difference of the SSH from different satellite altimetry missions and TGSL that are time co-located.…”

Abstract. Coupled with the occurrence of regional/local sea level rise on urbanized coastal cities is the possibility of land subsidence that contaminates the measurement by the tide gauge (TG) sensors. Another technology that could possibly check the in-situ data from tide gauge is satellite altimetry. The sea surface height (SSH) measured from satellite altimeter is compared with the observed tide gauge sea level (TGSL) to detect vertical land motion (VLM). This study used satellite altimeter retracked products near the TG Stations in Tagbilaran, Bohol; Dumaguete, Negros Oriental; and Mambajao, Camiguin located in the vicinity of the South East Bohol Trench and Fault (SEBTF).Based on the results, the TG site in Tagbilaran is undergoing land subsidence. The rate of VLM is around 5 mm/year from 2009 to 2017. The same trend was manifested in the GNSS observed data in the PHIVOLCS monitoring station in Tagbilaran and the geodetic levelling done in the area. After the October 15, 2013 earthquake in Bohol, downward trends of around 27 mm/year and 17 mm/year were observed from GNSS measurements and SSH-TGSL difference respectively. These different rates may be due to the distance between the two sensors. The comparison between SSH and TGSL in Dumaguete showed small difference with a VLM rate of 1.8 mm/year. The difference in SSH-TGSL in Mambajao is quite large with a downward rate of 9.4 mm/year. This result needs to be further investigated for TG or TGBM instability or monitored for a possibility of land uplift.

“…The Gravity Recovery and Climate Experiment (GRACE) is the first dedicated satellite time-variable gravity mission, and it offers a novel technique for monitoring large-scale mass changes in the Earth system (Tapley et al, 2004. The principle of GRACE is mapping the Earth's gravity field by measuring the changes distance between the pair of GRACE satellites with GPS and microwave ranging along the orbiting Earth (Zulkifli et al, 2018). The gravity variations analysed by GRACE satellite include the changes of the continental water and snow storage, variations of the sea-floor pressure, the mass balance of ice sheets and glaciers, and redistribution of mass on Earth, which serve as critical input for various fields of oceanography, hydrology, glaciology, and solid Earth science.…”

“…This is because, GLDAS data do not include the measurement of GWS. The GLDAS land model combines satellite and ground-based data products using the data assimilation technique to produce the most accurate land surface information (Rodell et al, 2004: Zulkifli et al, 2018. The GLDAS consist of aggregated anomalies in land water storage from soil moisture (SM), snow water equivalent (SWE), and surface water (SW), mainly storage of the plant canopy as predicted by land surface models.…”

Abstract. Water stored beneath the Earth’s surface, known as groundwater is a major water supply for living things. The increase in human population leading to high urban development and industrial needs in Malaysia has made the use of groundwater more critical. The current issue faced by Malaysia is the limitation of freshwater source from dam resulting in increasing demand to gather the source of fresh water from groundwater; hence, leading to the crucial exploitation of groundwater. Therefore, this study aims to evaluate groundwater storage (GWS) using Gravity Recovery and Climate Experiment (GRACE) and Global Land Data Assimilation System (GLDAS) data in Peninsular Malaysia. GRACE data consist information on the liquid water equivalent thickness covering terrestrial water storage (TWS) of GWS, soil moisture (SM), snow water equivalent (SWE), and surface water (SW). In comparison with GLDAS data, they only consist hydrological products of SM, SWE, and SW. Therefore, the differences between the GRACE and GLDAS data are most likely to reflect the information of GWS. Due to the seasonal monsoon, the changes in GWS can also be seen in specific months. In addition, the data can also be used to identify important areas that need improvement and attention. The output of this study is expected to help authorities monitoring the changes in GWS in recharge and discharge areas for future preservation of groundwater quality. Moreover, the excessive exploitation of groundwater can also be observed for the prevention of land hazard phenomena, such land subsidence.

“…Until the deployment of global navigation satellite system (GNSS) satellite constellations, land subsidence monitoring was carried out using leveling techniques [ 13 , 14 ]. New global positioning systems have improved the flexibility of monitoring networks, allowing the direct measurement of 3D deformations [ 15 ], alone or combined with satellite data [ 16 , 17 , 18 ]. The launch of synthetic aperture radar (SAR) satellites, the first in 1992 (ERS 1/2), provided a new way to monitor land subsidence over wide areas [ 19 ].…”

The launch of the medium resolution Synthetic Aperture Radar (SAR) Sentinel-1 constellation in 2014 has allowed public and private organizations to introduce SAR interferometry (InSAR) products as a valuable option in their monitoring systems. The massive stacks of displacement data resulting from the processing of large C-B and radar images can be used to highlight temporal and spatial deformation anomalies, and their detailed analysis and postprocessing to generate operative products for final users. In this work, the wide-area mapping capability of Sentinel-1 was used in synergy with the COSMO-SkyMed high resolution SAR data to characterize ground subsidence affecting the urban fabric of the city of Pistoia (Tuscany Region, central Italy). Line of sight velocities were decomposed on vertical and E–W components, observing slight horizontal movements towards the center of the subsidence area. Vertical displacements and damage field surveys allowed for the calculation of the probability of damage depending on the displacement velocity by means of fragility curves. Finally, these data were translated to damage probability and potential loss maps. These products are useful for urban planning and geohazard management, focusing on the identification of the most hazardous areas on which to concentrate efforts and resources.
