Second photo may have been same as first photo, just 20X as large and rubble everywhere after it fell. I think that was in NY near NYC if I recall properly.
Active earth pressure - all cantilever walls not restrained at top and not ridiculously stiff.
Passive pressure - Soil behind guardrail post after it has been hit that was pushed up.
RE: earth pressure on retaining walls
You fall because, active pressure (which is F=m*a acting on your body's mass centroid) causes more moment with respect to your feet's bottom, than passive moment caused by the stone. Imagine if stone was much larger, 1m tall, you will not fell over, because passive pressure is much more.
