ALOS PALSAR
Eric Fielding of JPL has prepared an unwrapped interferogram from ALOS path 533
using dates 2009/11/30 and 2010/04/17 (precise orbit). This is also available as a kmz file.

ScanSAR interferogram by David Sandwell. ScanSAR to ScanSAR interferogram derived from ALOS PALSAR acquisitions on December 23,
2007 and April 5, 2010. This is combined with a partial ALOS PALSAR ascending
interferogram. Increasing color is increasing range. The ascending interferogram has most
of the fringes on the northwest side of the fault near highway 2. This shows decreasing
range which represents motion toward the radar due to right lateral strike slip. The
pattern is asymmetric with almost no LOS deformation on the west side. This indicates
that the increasing range on the west side due to the right lateral strike slip is
largely cancelled by upward deformation on the west side. This is consistent with the
ascending interferogram which shows a decreasing LOS displacement on the northwest side
of the fault. These results indicate a combination of right-lateral strike slip and a
east-side-down normal faulting.
Unfortunately the correlation of the interferogram is poor along much of the fault partly
because of the very low SNR of these ScanSAR data.
KMZ file
David Sandwell and Matt Wei have prepared the first interferogram of the 2010 Baja event, using GMTSAR
to process PALSAR Track 213. Each fringe is 11.6 cm of displacement along the line of sight.
KMZ file
It would be very helpful if the following PALSAR images could
be acquired in FBS or FBD mode, level 1 processing:
T531 F2960-3000
T532 F2930-3000
T533 F2950-2990
T212 F0620-0650
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.
ERS-2:
It would be very helpful if the following SAR images could
be acquired with level 0 (raw) processing, in CEOS format:
Tracks 77 and 306, Frame 639
Track 84, 356 and 313, Frames 2925, 2943, 2961 and 2979
ENVISAT:
It would be very helpful if the following ASAR images could
be acquired in I2 mode, with level 0 (raw) processing:
Tracks 77 and 306, Frame 639
Track 84, 356 and 313, Frames 2925, 2943, 2961 and 2979
The more frequently the above images are acquired, the more we can learn about
the post-seismic strain field.

Eric Fielding of JPL has prepared an unwrapped interferogram from Envisat decending
track 84, using preliminary orbits and scenes from 2010/03/28 and 2010/05/02.

track 77, using preliminary orbits and scenes from 2010/03/28 and 2010/05/02.
Eric Fielding of JPL has prepared an unwrapped interferogram from Envisat decending
track 356, using dates 2010/03/12 and 2010/04/17. This is also available as a kmz file.
Eric Fielding of JPL has prepared a preliminary Envisat interferogram from ascending
track 306, using the pair from 2009/11/24 to 2010/04/13. This is also available as a kmz file.
Yuri Fialko of Scripps prepared an interferogram with Envisat, ascending track 306, Mar 9 2010 - Apr 13 2010 (preliminary orbits, perperdicular baseline of 270 m). Change in radar range is 2.8 cm per fringe. Mapped surface ruptures are shown in heavy black lines.

The NASA/JPL airborne repeat-pass InSAR system, UAVSAR will start the
first San Andreas 'lawn mowing' flight of 2010 on Monday, April 12.
The plan also contains one line over the Salton Sea, making it a total
of 14 lines repeating flight lines flown in 2009. These lines should
capture all of the deformation from the April 4th earthquake that we can
measure with UAVSAR. For more information please see
flightplans
at JPL.
UAVSAR completed the 14 flight lines on April 12, 2010, but some of the flight lines had to be reflown on April 13 due to unusually strong winds. Another similar set of lines was flown on July 1, 2010 under the request of Andrea Donnellan to study the postseismic deformation.
