$\begin{figure} \par\includegraphics[width=5.8cm,clip]{4604.f2.eps} %\end{figure}$ Figure 2: The deformation of the volcanic flank. a) The rotational slumping produces backward tilted blocks and arcuate scarps (I) within the flank of the volcanic center. b) The overlying load depresses the coalesced layer which becomes unstable resulting in lateral spreading of the cone and in fracturing of coherent material (II) due to plastic flow of the subsequent material (Modified after Sumner 1998).

$\begin{figure} \par\includegraphics[width=8cm,clip]{4604.f3.eps} %\end{figure}$ Figure 3: The left-looking radar image of the Mbokomu Mons (from Magellan image F-MIDR.15S/215;1). This Corona-nova (15S/215E) has a prominent graben system to the SW of the Nova center. The high-resolution image of the suite (white box) is shown in Fig. 5. The topographical profiles O-A and O-B are shown with the graben regions shaded in the profile. In profile O-A the vertical enlargement is $\times$ 83, and $\times$ 62 in profile O-B.

The high-resolution image of the graben (white box) is shown in Fig. 8. The topographic profile O-A is also shown with a vertical enlargement of $\times$ 27. The graben are located within the shaded regions.

The two white boxes show locations of graben in Fig. 8a ( upper) and Fig. 8b ( lower). The locations of the graben sets are shown within the topographical profiles O-A (with vertical enlargement of $\times$ 78) and O-B ( $\times$ 76).

There are actually two separate suites modifying the flank of this structure. b) The SW graben of Dhorani Corona. Although three different suites are seen, at least the set in the middle is somewhat obscured by the fractures of the corona rim.

$\begin{figure} \par\includegraphics[width=8.2cm,clip]{4604.f9.eps} \end{figure}$ Figure 9: The radar image (from left-looking Magellan image C1-MIDR.15S163;1) displays that the corona-nova (14S/164E) has also graben to the NE as well as to the SW of the nova center. The white boxes show locations of Fig. 10a ( upper) and Fig. 10b ( lower). O-A and O-B mark the topographical profiles with vertical exaggerations of $\times$ 83 for the profile O-A and $\times$ 70 for the profile O-B. The profiles have shaded areas showing the regions with graben.
