Land motion over UK mapped with unprecedented accuracy

UK InSAR motion map

TRE ALTAMIRA has processed more than 7,000 satellite radar images acquired over the UK since 2015 to generate a nation-wide database of displacement measurements with unprecedented accuracy. Our pioneering experience of national-scale processing dates back 10 years when we were involved in the processing of the entire European Space Agency radar satellite data archive acquired…

InSAR nationwide monitoring: the Italian case

InSAR Monitoring over Italy

TRE ALTAMIRA together with E-geos have processed thousands of SAR images to cover the entire Italian territory within the framework of the PST project (Piano Straordinario di Telerilevamento), which went live in 2008, years prior to the launch of Sentinel-1 satellites. The PST results are now presented in the article: “Analysis of surface deformations over…

Can InSAR contribute with new insights into possible earthquake precursors?

Co-seismic interferogram #L'Aquila

This controversial issue is under analysis in a paper co-authored by Fabrizio Novali, R&D manager of TRE ALTAMIRA, now published in Scientific Reports – Nature.   Seismologists at INGV (Istituto Nazionale di Geofisica e Vulcanologica) have analysed ground displacement before and after the L’Aquila earthquake, which struck the central part of Italy in April 2009…

Néuquen Basin: Sentinel-1 ground deformation study

InSAR ground deformation maps #Néuquen-Basin

We are pleased to be featured in the latest issue of Géologues, the French Geological Society magazine. The article “L’interférométrie radar au service de la cartographie et de la surveillance des mouvements du sol. Application à l’étude des déformations dans le bassin de Neuquén (Argentine)” details our InSAR project with the multinational company TOTAL to…

Long-term satellite study over the London basin

Snapshot from London InSAR motion map

We have recently explored the use of large-scale, multi-temporal and multi-sensor imagery over the London basin, an area about 250 km-long, starting from 1992 up to date. This project was established as scope of an internship between the Imperial College London and TRE ALTAMIRA. By combining over 500 radar images from different satellites (i.e. ERS,…

Precursor of Maoxian Landslide Measured from Space

SqueeSAR™ measurements reveal clear, precursory movements of the ground months before the Maoxian landslide occurred. On 24 June 2017, a massive landslide hit a village in Maoxian county in Sichuan province, south-western China, destroying 40 homes and killing dozens of people (BBC news here). Authorities suggest the event was triggered by prevailing heavy rains. TRE…
