BEYOND EO Center was mobilized to assess the spread of the oil spill in the Red Sea, and produced this map depicting the observed oil spill extent from the Iranian SABITI crude oil tanker, which was attacked on October 11th 2019 off Jeddah's coast.

The oil leak status has been captured by two Sentinel-1B satellite images on 13-10-2019 with an estimated length of 489 km in yellow color, and by two Sentinel-1A satellite images on 14-10-2019 with an estimated length of 710 km in pink color. All satellite images were acquired by the Hellenic Mirror Site of BEYOND, NOA.

It is undoubtedly a large disaster, rendering a severe contamination effect.

BEYOND will continue to monitor the oil spill for the next few days in order to detect changes and assess the level of marine pollution.

In July 1, 2022, 23:25:15 UTC, an M6.3 earthquake occurred in Southern Iran. Co-seismic deformation was mapped by the geObservatory service of BEYOND Center of Earth Observation Research and Satellite Remote Sensing of the National Observatory of Athens. The first co-seismic interferogram was produced with the use of two Sentinel-1 images of June 22, 2022 and July 4, 2022 of ascending satellite track 130. In the co-seismic interferogram, surface deformation induced by the seismic event is clearly presented bυ numerous fringes. 11 fringes can be detected. Each fringe corresponds to a ground deformation equal to 2.8 cm, resulting to an overall of almost 30 cm of ground deformation. All co-seismic and pre-seismic interferograms, associated with the event are freely available in the geObsevatory website (http://geobservatory.beyond-eocenter.eu/).

On January 07, 2022, 17:45:31 UTC a strong earthquake of M6.2 occurred in Northern Qinghai, China. geObservatory service of BEYOND Center of Earth Observation Research and Satellite Remote Sensing of the National Observatory of Athens, was activated and detected co-seismic deformation induced by the seismic event. The first co-seismic interferogram, was generated from Sentinel-1 SLC images of descending track 33, of December 29, 2021 and January 10, 2022. Each fringe in the interferogram corresponds to ground deformation equal to 2.8 cm. All co-seismic and pre-seismic interferograms, associated with the event are freely available in the geObsevatory website (http://geobservatory.beyond-eocenter.eu/), which is updated with new interferograms as long as new Sentinel-1 satellite data becomes available at the Hellenic Mirror Site.

First co-seismic interferogram of Haiti region earthquake.
On August 14, 2021, 12:29:09 UTC a strong earthquake of M7.2, occurred in Haiti region. It was followed by a second seismic event of M5.9, on August 15, 2021, 03:20:45 UTC. The geObservatory service of BEYOND Center of Earth Observation Research and Satellite Remote Sensing of the National Observatory of Athens, was activated and mapped ground deformation in the affected region. Sentinel-1 SLC images of descending track 142, of August 3, 2021 and August 15, 2021, were used to produce the first co-seismic interferogram, where deformation of both seismic events is mapped. Each fringe in the interferogram corresponds to ground deformation equal to 2.8 cm. All co-seismic and pre-seismic interferograms, associated with the events are freely available in the geObsevatory website (http://geobservatory.beyond-eocenter.eu/). The website will be updated with new interferograms as long as new Sentinel-1 satellite data becomes available at the Hellenic Mirror Site.

Παιανίας.

Θα χαρούμε να σας συναντήσουμε στο περίπτερο μας, για να γνωρίσετε από κοντά τόσο τις υπηρεσίες μας όσο και τους ανθρώπους πίσω από αυτές, αλλά και στην Ημερίδα μας που θα διοργανωθεί στο πλαίσιο της έκθεσης, στο “Verde.tecForum”.

Το Κέντρο Αριστείας BEYOND μέσω της υπηρεσίας του geObservatory παράγει αυτόματα όλα τα αναγκαία συμβολογραφήμματα (interferograms)  πριν και μετά τον σεισμό και δίνει τη δυνατότητα λήψης των εικόνων (interferograms) για περαιτέρω ανάλυση στην επιστημονική κοινότητα. 

Την Παρασκευή 24.01.2020 στις 20:55 (τοπική ώρα) σημειώθηκε σεισμική δόνηση μεγέθους 6,9 βαθμών Ρίχτερ με 10 μέτρα εστιακό βάθος στην Ανατολική Τουρκία και συγκεκριμένα στην περιοχή Ελαζίγ. Μέχρι στιγμή ο τραγικός απολογισμός είναι 41 νεκροί.

Συγκεκριμένα για τον πρόσφατο καταστροφικό σεισμό στην ανατολική Τουρκία έγινε εκτίμηση της εδαφικής παραμόρφωσης στην περιοχή, μέσα από την επεξεργασία δορυφορικών εικόνων Sentinel-1 που συλλέχθησαν στα Copernicus Hubs που λειτουργεί το BEYOND/EAA.

Η ανάλυση του σεισμού (co-seismic interferogram) έγινε με εικόνες πριν και μετά τον σεισμό (Master 2020-01-21 15:25:22, Slave 2020-01-27 15:25:50) και παρατηρούμε ένα μοτίβο κροσσών συμβολής που αντιστοιχούν σε μετατόπιση του εδάφους. Ο αριθμός των κροσσών ίδιου χρώματος δείχνει το μέγεθος της μετατόπισης (2,8 cm ανά κροσσό). Στο αντίστοιχο pre-seismic interferogram ( Master 2020-01-21 15:25:22, Slave 2020-01-15 15:25:50 ) που έχει δημιουργηθεί με εικόνες πριν τον σεισμό δεν παρατηρούνται κροσσοί.

Η υπηρεσία geObservatory είναι ανοιχτή και ελεύθερη για χρήση από όλη την επιστημονική κοινότητα η οποία μπορεί να  χρησιμοποιήσει όλα τα παραγόμενα συμβολγραφήμματα για πιο εξειδικευμένες αναλύσεις. Οι χρήστες καλούνται να επισκεφτούν την υπηρεσία geObservatory http://geobservatory.beyond-eocenter.eu/ και να χρησιμοποιήσουν την online γεωχωρική εφαρμογή για να δουν και να κατεβάσουν τα διαφορικά συμβολογραφήμματα, τόσο για τον σεισμό της Ανατολικής Τουρκίας, όσο και για άλλα σημαντικά σεισμικά γεγονότα παγκόσμια.

EMS Activations

Copernicus EMS - Mapping provides all actors involved in the management of natural disasters, man-made emergency situations and humanitarian crises, with timely and accurate geospatial information derived from satellite remote sensing and completed by available in situ or open data sources. The information generated by the service can be used as supplied (e.g. as digital or printed map outputs). It may be further combined with other data sources (e.g. as digital feature sets in a geographic information system). In both cases it may support geospatial analysis and decision making processes of emergency managers. Copernicus EMS - Mapping is provided during all phases of the emergency management cycle, in two temporal modes, and free of charge for the users. It can be activated only by authorized users.

The infrastructure and excellence developed in the BEYOND Center of Excellence are actively involved in the provision of Risk & Recovery Mapping which consists of the on-demand provision of geospatial information in support of Emergency Management activities related to Emergency Support. This applies in particular to activities dealing with prevention, preparedness, disaster risk reduction and recovery phases. There are three broad product categories: Reference Maps, Pre-disaster Situation Maps and Post-disaster Situation Maps. The research developed in BEYOND, exploits satellite data and ingests fusions of geo-partial information and data in rush mode, when, where needed, for enhanced risk modelling and improved assessment of the expected disaster impacts.

The list of methodologies developed, adapted, validated, and used in BEYOND to address risk and recovery needs of the civil protection authorities worldwide are listed below (in more details in ANNEX III):

  • Seismic Methodologies: Seismic Hazard, Seismic Vulnerability, Seismic Vulnerability of Pipelines, Seismic Risk.
  • Lava Flow Methodologies: Lava Flow Hazard, Lava Flow Vulnerability, Lava Flow Risk.
  • Forest Fires Methodologies: Fire Damage Delineation & Burn Severity Grading, Damage/Biomass Loss Statistics, Forest Fire Hazard, Population & Assets Vulnerability to Forest Fires, Forest Fire Risk – Population, Assets and Transportation Network at risk.
  • Industrial Accidents Methodologies: Industrial Accidents Hazard, Industrial Accidents Exposure, Industrial Accidents Risk.
  • Tsunami Methodologies: Tsunami Hazard Assessment, Assets Vulnerability to Tsunami, Storm Surge Hazard Risk.
  • Soil Erosion Methodology: Soil Erosion Hazard.
  • Coastal Erosion Methodology: Coastal Erosion Vulnerability.
  • Ground Deformation Methodology: Ground Deformation Dynamics.
  • Landslides Methodology: Landslide Hazard, Landslide Vulnerability, Landslide Risk.
  • Subsidence and Landslide Methodology: Subsidence and Landslide Risk.
  • Floods Methodology: Flood Delineation at peak conditions, Flood Depth at peak conditions, Flood Damage Assessment, Flood Hazard, Flood Vulnerability, Flood Risk, Flash Flood Hazard triggered by earthquakes, Flash Flood Risk triggered by earthquakes.
  • Disruption of Transportation Networks Methodology: Vulnerability of Disruption of Transportation Networks.

Up to now the BEYOND Center has been activated in the framework of the COPERNICUS EMERGENCY MANAGEMENT SERVICE in the following worldwide disaster risk and recovery cases :
