  2. Cráteres de Impactos de cometas y asteroides Cráter Aristarco, Luna

  3. Cráter Manicouagan, Canada 100 km, 212 Maño Crater Doble Clearwater, Canada 32 y 22kkm, 290 Maño Cráter Meteórico Barringer, Arizona 1.2 km, 49.000 año

  4. Gravity-regime: rV rV m m -3m/(2+m) r ga ( ) ( ) µ d U2 rV m 2+m-6n 2+m Simple scaling model Crater size = F [ {impactor prop}, {target prop}, {env. prop.} ] V = F [ aUmdn, r, Y, g ] Strength-regime: -3m/2 r 1-3n Y ( ) ( ) µ d rU2 ga/U2 (from Housen 2003) †

  5. Cratering in metals Regression gives n=0.4, m=0.5 Ref: Holsapple and Schmidt (1982) JGR, 87, 1849-1870.

  6. Regímenes de Impacto

  7. Regímenes de Impacto II

  8. Pi-scaling Strength Regime Gravity Regime Cratering law

  9. Radius of transient crater d= depth Rfinal = 1.3 R d/Dfinal~ 0.2

  10. In the gravity regime Diameter of transient crater Diameter of final rim Depth of transient crater Depth of final rim (Collins et al. 2005)
