Using displacement gradient grid from optical image correlation, fault rupture trace, from Sep 28 #earthquake, can be mapped in detail. #Fault can be seen through Palu city. #Paluearthquake. Displacement using MicMac & PlanetLabs imagery.
New #InSAR map of deformation from #PaluEarthquake from NASA Caltech-JPL analysis of JAXA ALOS-2 PALSAR-2 data acquired last week. Color contours are 12 cm (4.8 in.) each in this wrapped interferogram map. More soon. KMZ and GeoTIFF available at https://t.co/nRh1s2DMg0
Line-of-sight deformation from ALOS-2 for the Palu earthquake (data provided by JAXA, processed using GMTSAR). Unwrapping is challenging for this earthquake! Some near-fault region is too decorrelated to be trustworthy.

@seismolucy @BaptisteGomb @stef92320 @SotisValkan@EricFielding Yes, that may have happened here. The figure summarizes our supershear-from-the-outset observation.
Also interesting: 4.2 km/s is close to Eshelby speed = sqrt(2) x S wave speed. At this speed there is no shear Mach wave, but still a Rayleigh Mach front (https://t.co/Jr0rnKsw1i)
Shallow afterslip following M7.5 Palu #earthquake. 12-day interferogram (Oct4-Oct16) from ascending pair of #Sentinel1, w/DIAPASON at @esa_gep. Patches of afterslip follow the ruptured plane (hangingwall), small higher peaks found along the trace. Each fringe is ~2.8cm LOS.
emm..
izinkan sy menyampaikan fakta,
khusus area kab.pekalongan;
bahwa semarak medsos tentang timses & relawan
@prabowo@sandiuno di pusat sana;
hingga saat ini blm ada pengaruh di masyarakat bwh!
mukidi msh menjadi idola!
data sy dpt dari setiap hari gerilya di basis petahana.
Alhamdulillah, hari ini genap setahun bertugas di Jakarta, mensyukuri bahwa satu per satu janji ditunaikan dan kita tetap berkomitmen terhadap apa yang sudah direncanakan.
