Fig. 7From: Gravity changes observed between 2004 and 2009 near the Tokai slow-slip area and prospects for detecting fluid flow during future slow-slip eventsDistribution of x2 (Eq. (3)) in the inverse analysis of the gravity change rates. The horizontal and vertical axes denote the permeability κ and the width W of the fluid conduits, respectively. Color contours are drawn only in areas where x2 < 4.5.Back to article page
