Listric Normal Faulting with Reverse Drag
Listric Normal Faulting with Rollover
Occurs due to space problem with curved detachment
Imbricate Listric Normal Faulting
Synthetic faults also accommodate collapse of HW block
Imbricate Listric Normal Faulting
“Meatslices common in large displacement systems
