ERS and ENVISAT multitemporal interferometric analisys to characterise land subsidence and uplift in Phoenix (Arizona)

  • In this study the team show the usefulness of InSAR for examining surface deformation due to groundwater withdrawal and recharge in Phoenix, Arizona. Multi-track ascending and descending ERS SAR datasets from 1992-1996 and ENVISAT ASAR , 2003-2010 are combined to obtain vertical and horizontal (east-west) displacement time series components.
  • The result has been presented in the paper "Spatiotemporal characterization of land subsidence and uplift in Phoenix using InSAR time series and wavelet transforms", authored by Megan Miller and Manoochehr Shirzaei,, and published in July 2015 in the JOURNAL OF GEOPHYSICAL RESEARCH - Solid Earth doi:DOI: 10.1002/2015JB012017, 2015.

ASU researchers find complex relationship between major earthquake faulting and mountain building in the Himalaya

  • The April 2015 Gorkha earthquake in Nepal killed more than 8,000 people and injured more than 21,000. With a magnitude of 7.8, it was the worst natural disaster to strike Nepal since the 1934 Nepal-Bihar earthquake.Researchers Kelin Whipple, Manoochehr Shirzaei, Kip Hodges, and Ramon Arrowsmith of ASU’s School of Earth and Space Exploration were quick to begin analyzing the data from this quake. Their findings have been recently published in Nature Geosciences.
