Table 1 Key features of the three investigated landslides

Features	Melas Chasma	Ophir Labes	Coprates Labes
Runout (km)	100–120	40/60/65	65
Deposit area (km²)	2500	2700	1900
Source area (km²)	70	60	330
Fall height (km)	9	6	4.5
Volume, Quantin et al. (2004a) (km³)	376	458	346
Fahrböschung	0.075	0.120	0.069

We list the runout distance, the area of the deposit and of the source, the maximum fall height, the estimated volume, and the Fahrböschung (i.e., the fall height divided by the runout)
