Cráter Meteórico Barringer, Arizona 1.2 km, 49.000 año Crater Doble Clearwater, Canada 32 y 22kkm, 290 Maño Cráter Manicouagan, Canada 100 km, 212 Maño
5
Simple scaling model Crater size = F [ {impactor prop}, {target prop}, {env. prop.} ] V = F [ aU,, Y, g ] Strength-regime: 1-3 -3 /2 ) ( ) Y U 2 ( V m V m ga/U 2 Gravity-regime: -3 /(2+ ) ) ( ) ga U2U2 ( 2+ -6 2+ V m (from Housen 2003)
6
Cratering in metals Ref: Holsapple and Schmidt (1982) JGR, 87, 1849-1870. Regression gives =0.4, =0.5

Pi-scaling Strength RegimeGravity Regime Cratering law
12
Radius of transient crater depth R final = 1.3 R d/D final ~ 0.2 d=d=
13
In the gravity regime Diameter of transient crater Diameter of final rim Depth of transient crater Depth of final rim (Collins et al. 2005)
