Regional Gravity NOAA-FA data analysis using several gradient methods has been conducted to determine the fracture and direction fault based on FFT. Fault can be qualitatively identified from a regional anomaly data. gradient Theta and Normalized Standard Deviation (NSD) is trending north-south. Dominant fracture orientation parallel to the fault is only detectable by gradient Theta a... https://stehlenautomotivers.shop/product-category/grille-guard/
