The lowering or sinking of the ground’s surface, referred to as land subsidence, can cause serious damage to infrastructure and private property, and in turn, have an adverse impact on communities, individuals, and the economy. The European Space Agency’s (ESA) Sentinel-1 satellite, part of the Copernicus programme, is being used to monitor cases of land subsidence and contribute to risk assessment and urban development efforts.

From Sentinel-1 radar data collected over time, ground deformation maps can be created, which provide important insights to local authorities charged with implementing hazard mitigation and management strategies. For example, such maps recently helped authorities in... read more

Comparing surface deformation data through Envisat and Sentinel-1A data over Bay of Naples in Italy (Image: ESA)

The remote sensing technique to map ground deformation is being improved thanks to scientific work based on frequent observations from the Sentinel-1A radar satellite data.

The one-year old satellite data has been compared with those from the ERS and Envisat, former satellite radar missions. This work has enabled researchers of Italy’s Institute for Electromagnetic Sensing of the Environment (IREA-CNR) to show a drastic improvement in mapping surface deformation and to draw a new path for earthquake and volcano monitoring.

“To achieve this, the scientists used the Interferometric Synthetic Aperture Radar, or InSAR, technique. This involves combining two or more radar images acquired at different times. If something on the ground has changed between the acquisitions, the terrain deformation is displayed as a continuous sequence of coloured stripes called interference fringes, or an ‘interferogram’,” explains the European Space Agency on their website.

The mean... read more

Earth’s changing surface can be closely monitored thanks to the use of satellite radar data. This week at the Fringe Workshop held by the European Space Agency ESA, new advances in the science and applications of Interferometric Synthetic Aperture Radar (InSAR) were presented.

InSAR is a remote sensing technique where two or more images of the same area are combined to detect slight changes occurring between acquisitions. ESA elaborated: "Tiny changes on the ground cause changes in the radar signal and lead to rainbow-coloured interference patterns in the combined image, known as an ‘interferogram’. Small movements – down to a scale of a few millimetres – can be detected across wide areas. Tectonic plates grinding past one another, the slow ‘breathing’ of active volcanoes, the slight sagging of a city street through groundwater extraction, and even the thermal expansion of a building on a sunny day."

Height of Bangladesh mangrove

More than 275 researchers from around the world gathered last week at the biennial POLinSAR and first Biomass science workshops hosted at ESA’s centre for Earth observation in Frascati, Italy. Polarimetric InSAR – or POLinSAR – is a remote sensing technique based on combining polarimetric and interferometric information in synthetic aperture radar images.

ESA reported: "One of the examples presented at the POLinSAR gathering shows how the height of Bangladeshi mangrove forest, which is an important local resource, can be mapped from space. This example uses data from the German TanDEM-X satellite along with POLinSAR." The technique of POLinSAR has matured considerably over recent years and scientists are now looking forward to further advances that will come once ESA’s Biomass mission is launched 2020.

Images collected by Envisat have been used to monitor the ground

Data collected by satellite has been used to establish the stability of the ground sustaining the Basilica di Massenzio in Rome, the largest of the ancient buildings that make up the Roman Forum. ESA explains on their website: "With the help of the satellite images, the geologists could tell very quickly if a particular hillside had slid a little over the years, or if the ground under a house had sunk a bit.

In order to measure if the vibrations coming from the modern-day Roman traffic and expansion of Rome's metro line was affecting the stability of the building, geologists and engineers made use of satellite images collected by Earth observation missions like ERS and Evnisat. The images were used to determine if there had been any movement of the ground beneath the structure.

Previously, when they suspected any movement of the ground, experts had to wait several months to confirm or discard their suspicions. With the new technique experts were able to measure any... read more

River Nile and its Delta hosting two of the biggest cities in Egypt

Flood is one of the most common geohazards, which also costs most devastation to society. There are areas more vulnerable to floods, where measures are taken to mitigate the impacts, but further research is needed for identifying flood vulnerability in order to make communities in such vulnerable areas more resilient.

Professor Alberto Montanari from the University of Bologna found new ways of pinpointing vulnerable areas by using satellite observation of night time lights from homes or businesses and combining this data with river network data.

The Institute of Hazard, Risk and Resilience explains: "Since night lights are a useful indicator for human settlements it can be used to identify and prioritise vulnerable populations that live close to streams or rivers. The data presented by Montanari shows an increase in night lights in areas... read more

The plumes of sediment are clearly visible in the Mediterranean.

Heavy rainfall caused flooding in southeastern France and northern Italy. On the images taken by the MODIS sensor on NASA’s Terra satellite, the mud-laden runoff is clearly visible creating tan and green plumes of sediment in the Mediterranean.

The floods caused two deaths and forced widespread evacuation. BBC reported on the situation in France: “By Sunday evening, 155 people had been airlifted from the worst-hit areas and the evacuation of residents by boat was continuing.” In Italy, the regions around Bologna, Genoa and Florence experienced widespread flooding, with the city of Modena, in the Emilia-Romagna region, particularly affected.

As well as providing critical information about ice, CryoSat has also demonstrated that it can offer a valuable source of data for oceanography, hydrology and geodesy.

The conference therefore provides a forum for international scientists and operational users to present and share state-of-the-art CryoSat-based results, its decadal contribution to science and future perspectives in the following areas:

  • Sea ice
  • Greenland and Antarctica icesheets
  • Glaciers and ice caps
  • Oceans and marine gravity
  • Hydrology
  • Icebergs & ice shelves
  • 10 Years of operations, synergies and future missions

The International Conference on Disaster Management is being reconvened following the success of the previous meetings, held at Wessex Institute in the New Forest in 2009, the University of Central Florida in Orlando, USA in 2011, A Coruña, Spain in 2013, Istanbul Technical University, Turkey in 2015 and Seville, Spain, 2017.

This series of conferences originated with the need for academia and practitioners to exchange knowledge and experience on the way to handle the increasing risk of natural and human-made disasters. Recent major earthquakes, tsunamis, hurricanes, floods and other natural phenomena have resulted in huge losses in terms of human life and property destruction. A new range of human-made disasters have afflicted humanity in modern times; terrorist activities have been added to more classical disasters such as those due to the failure of industrial installations for instance.

It is important to understand the nature of these global risks to be able to... read more
