Subsurface mechanical architecture of coronae on Venus and its implications for processes governing fractures and seismicity

Figure 2 The investigated coronae are all shown on the global Magellan synthetic aperture radar left-look mosaic base map: Atahensik (panels a–c), Demeter (panels d–f), Didilia (panels g–i), Heng-O (panels j–l), Kamui-Huci (panels m–o), Ninkarraka (panels p–r), Pavlova (panels s–u). Magellan global topography (4641 m/px) is displayed in panels b,e,h,k,n,q,t. The…
