N2 - Multichannel Analysis of Surface Waves (MASW) is a non-invasive, fast and low-cost seismic exploration method for evaluation of near-surface shear wave velocity (VS) profiles. MASWaves is an open source software for acquiring and analyzing MASW field data that has been under development for the past few years. To date, MASW measurements have been carried out at over twenty different locations in Iceland, ranging from sites characterized by peat and loosely compacted sand to cemented soil materials and soft rock. The methodology used for acquiring and analyzing the surface wave records is described, with emphasis on recent advances in both in-situ procedures and data analysis. A newly developed open database is further introduced where results of MASW measurements carried out at Icelandic sites can be viewed and shear wave velocity/stiffness profiles for different sites compared. The aim is to give engineers and researchers access to the data and allow utilization of the results for, e.g., evaluation of seismic hazard and liquefaction potential, and for defining site-specific earthquake loading according to EC8.
