Το Κέντρο Αριστείας BEYOND του ΕΑΑ παρήγαγε ένα πρώτο διαφορικό συμβολόγραμμα που αφορά τον σημερινό σεισμό στη Ζάκυνθο και στο οποίο δεν ανιχνεύεται κάποια εδαφική παραμόρφωση.

Για την ανάλυση χρησιμοποιήθηκαν δεδομένα Sentinel-1 και η επεξεργασία των εικόνων ξεκίνησε αυτόματα με τη λήψη της πρώτης διαθέσιμης εικόνας μετά τον σεισμό.

Η υπηρεσία geObservatory είναι διαθέσιμη στη σελίδα :

http://beyond-eocenter.eu/geohub/ του Κέντρου Αριστείας BEYOND και παράγει αυτοματοποιημένα προϊόντα συμβολομετρίας μετά από σημαντικά σεισμικά γεγονότα και ηφαιστειακές εξάρσεις οπουδήποτε στον κόσμο.

Οι χρήστες μπορούν να προβάλλουν και να κατεβάζουν ελεύθερα τα προϊόντα που βρίσκονται στην εφαρμογή geObservatory.


Α quicklook of the differential interferogram produced for today’s earthquake in Zakynthos island, Greece. This is a raw interferogram, and no manual operations for fine-tuning the processing parameters have been applied.
No fringe pattern is evident in the island.

Sentinel-1 data were used and a fully automatic processing engine was activated a few minutes after the earthquake occurrence. This engine is named geObservatory and a beta-version front-end is available here:

Note that this is work in progress and any feedback on the functionality of geObservatory is welcome!

The event’s specific page is available here:

More interferograms will automatically populate this page as new Sentinel-1 data arrive.

Users can freely visualize and download the raw interferograms that are output from the geObservatory application of BEYOND Center Of Excellence.

 

After a week of intense micro-seismic activity in the wider area of the Kīlauea volcano in Hawaii, suddenly last Thursday a volcanic crack appeared near the road network, from which lava and hot steam appeared. The Civil Protection instructed residents of the Puna community (~ 10,000) to leave their homes immediately. On Friday, May 4, 2018, a powerful 6.9 earthquake hit the Big Island, the largest in the past 43 years.

The 2018 Oaxaca earthquake occurred on February 16, 2018 at 17:39 local time (23:39 UTC) in the Sierra Madre del Sur in Oaxaca state in Southern Mexico. It had a magnitude of 7.2 on the moment magnitude scale and a maximum felt intensity of VII (very strong) on the Mercalli intensity scale. The hypocenter was located at a depth of 24.6 km and approximately 37 km northeast of Pinotepa de Don Luis.

On 12/11/2017, late Sunday, an earthquake of magnitude 7.3 struck near the border of Iran and Iraq. At least 452 people were killed and thousands injured, while the earthquake was felt as far away as Turkey and Pakistan. Around 100 of the dead are believed to be from one town in Iran's Kermanshah province. Mapping of the surface deformation with Sentinel-1 data, available through the Greek Mirror Site (https://sentinels.space.noa.gr/).

The main earthquake event, Mw=7,8, occurred just after midnight, on Monday 13/11/2016, near the coastal community of Kaikoura-New Zealand, 93 kilometers NE of the city of Christchurch. A series of powerful aftershocks jolted New Zealand's South Island, triggering a tsunami and sending aftershocks across the country with at least two, officially reported, casualties. Shortly after the earthquake, four successive ascending Sentinel-1 Synthetic Aperture Radar images were acquired, two before (3/11/2016) the devastating earthquake and two after (15/11/2016).
