Mapping and analysis of the Central Italy Earthquake (2016) with Sentinel-1 A/B interferometry

Marinkovic, Petar; Larsen, Yngvar

Results Description

Background

A 6.2M earthquake hit Central Italy, the area of city of Amatrice, on 24 August 2016. The quake epicentre was southeast of Norcia, Italy, in an area near the borders of the Umbria, Lazio, Abruzzo and Marche regions. The quake hypocentre was at a depth of approximately 5 km.

InSAR

We computed a set of coseismic Sentinel-1A/B interferograms, over the affected area.

  • Descending track 95: S1A (2016-08-26) / S1A (2016-08-14)
  • Descending track 22: S1A (2016-08-21) / S1B (2016-08-27)
  • Ascending track 117: S1B (2016-08-21) / S1A (2016-08-27)

Earthquake Motion Decomposition

We also performed the two-dimensional earthquake motion decomposition. As an input for the decomposition, data of tracks 22 descending and 117 ascending were used, since they provide the full coverage of the earthquake.

Results and Data Package

Descending Interferogram, Track 95:

  • Goldstein filtered wrapped interferometric phase, 16x4 ML (KMZ format)
  • Interferometric coherence (KMZ format)
  • Descending Interferogram, Track 22:
  • Goldstein filtered wrapped interferometric phase, 16x4 ML (KMZ format)
  • Interferometric coherence (KMZ format)
  • Full geo-coded Goldstein filtered wrapped interferogram, 16x4 ML (GeoTiff format)
  • Intereferorgram subset (GeoTiff format)
    • Specifically for subset: 8x2 ML + goldstein + unwrapping + geocoding, incl oversampling to 10 m + smoothing (5x5 pixel boxcar) + subsampling to ~50m + calibrated at the point at used for 2D decomposition

Ascending Interferogram, Track 117:

  • Goldstein filtered wrapped interferometric phase, 16x4 ML (KMZ format)
  • Interferometric coherence (KMZ format)
  • Full geo-coded Goldstein filtered wrapped interferogram, 16x4 ML (GeoTiff format)
  • Intereferorgram subset (GeoTiff format, 7Mb zip file)
    • Specifically for subset: 8x2 ML + goldstein + unwrapping + geocoding, incl oversampling to 10 m + smoothing (5x5 pixel boxcar) + subsampling to ~50m + calibrated at the point at used for 2D decomposition

Decomposed Solution

  • Vertical Component (KMZ format)
  • East-West Component (KMZ format)
  • Vertical Component (GeoTiff format)
  • East-West Component (GeoTiff format)

Additional Information

  • Filenames are self descriptive and not require additional information
  • KMZ and GeoTiff files that are available for download, are generated for high-resolution investigations in GoogleEarth and post-processing & interpretation. They are not prepared for overviews, and thus are not heavily smoothed nor filtered.

Terms and Conditions: All Sentinel-1 results that are available for download are Derived Works of Copernicus data (2014-2016), subject to the "TERMS AND CONDITIONS FOR THE USE AND DISTRIBUTION OF SENTINEL DATA AND SERVICE INFORMATION".
