Earthquake, 13 April 2010 13:23 UTC, Latitude 32.27°S,Longitude 96.63°E, 6.9, Depth 10 km (USGS).

If you have data or results that you would like to post on this webpage, please e-mail Falk Amelung, the Task Leader of GEO's Supersite initiative (famelung@rsmas.miami.edu) or Susanna Gross (sjg@unavco.org). If appropriate, a KMZ file is convenient to use in the field.

SAR Data

Natural Laboratory ESA SAR Data for Download index of SAR data for download

Tim Wright of of School of Earth and Environment, University of Leeds, UK is coordinating data requests for this supersite.

ALOS PALSAR

tracks 487 and 488 frames 640 and 650
archive orbits 21189 and 21437

tracks 137 and 138 frames 2950 and 2960
archive orbits 14909 and 15157

The more frequently the above images are acquired, the more we can learn about the post-seismic strain field. It would be very valuable to get every possible orbit for the first few months.

Zhenhong Li of the University of Glasgow has provided this latest (Apr 25) PALSAR interferogram. A rewrapped ALOS PALSAR interferogram from Path 487 (ascending) superimposed on a hill-shaded SRTM DEM. The black line represents the surface rupture (txt file) derived from offset maps. For more information, please see his Yushu web page.

Guangcai Feng of the Hong Kong Polytechnic University has provided this PALSAR wrapped interferogram from Track 487 and Frames 640 and 650 (ascending orbit). For more information, please see his report.

Guangcai Feng of the Hong Kong Polytechnic University has provided these PALSAR Range and Azimith offset maps. For more information, please see his report.

Zhenhong Li of the University of Glasgow provided these PALSAR range and azimuth offset maps. Range offset map shows the range change in the satellite line of sight (LOS) whilst Azimuth offset map shows displacements in the azimuth direction (nearly North-South); therefore the latter is sensitive to surface movements in the N-S direction. For more information, please see his Yushu web page.

ERS-2:

It would be very helpful if the following SAR images could be acquired with level 0 (raw) processing, in CEOS format:

(a) Track 004 (Descending): Frames: 2907, 2925, 2943, 2961
(b) Track 276 (Descending): Frames: 2907, 2925, 2943, 2961

ENVISAT:

It would be very helpful if the following ASAR images could be acquired in I2 mode, with level 0 (raw) processing:

IM mode:
(a) Track 004 (Descending): Frames: 2907, 2925, 2943, 2961 First post-seismic image: 2010-04-27 (preferred over WS mode)
(b) Track 276 (Descending): Frames: 2907, 2925, 2943, 2961 First post-seismic image: 2010-05-16
(c) Track 455 (Ascending): Frames 639, 657, 675, 693 First post-seismic image: 2001-04-23
(d) Track 498 (Ascending): Frames 639, 657, 675, 693 First post-seismic image: 2001-04-26

WS mode:
(e) Track 004 (Descending): First post-seismic image: 2010-04-27 (if IM mode not acquired)
(f) Track 083 (Ascending): First post-seismic image: 2010-05-02
(g) Track 226 (Ascending): First post-seismic image: 2010-05-12
(h) Track 233 (Descending): First post-seismic image: 2010-05-13

The more frequently the above images are acquired, the more we can learn about the post-seismic strain field.


Track 498 interferogram from the COMET+ group. Unwrapped ENVISAT ascending interferogram covering the western part of the fault rupture overlain on hillshaded topography. Peak deformation away from the satellite is 18 cm, and towards the satellite is 3 cm. (bottom) Interferogram wrapped to 2.8 cm contours of deformation. Coloured fringes indicate surface deformation in the satellite line-of-sight. Cycles of colour from blue to red indicate the ground has moved away from the satellite. SAR data from the European Space Agency (ESA). For more information, please see the COMET website.
