Chile sinkhole DOUBLES in size to 160ft wide and more than 650ft deep - large enough to engulf France's Arc de Triomphe - days after it appeared near small town

High hopes, from Chinese slopes,
engulfing the Arc de triomphe!
Vertical shears, faulty gears,
and nothing to support the oomph.

#12  Well...not out loud

#11  A vertical shear indicates differential soils with no vertical support below IMHO

So you're saying it's aliens.

#10  sloping walls only possible if there is support at bottom.

So you're saying it's bottomless.

#9  sloping walls only possible if there is support at bottom. of wall. The less support, the more vertical the sides.

#7  Sloping indicates somewhat uniform soil with cohesion (clay/sedimentary, etc.). A vertical shear indicates differential soils with no vertical support below IMHO

#6  Black hole or earthly rectal inversion ?

#5  Should be safe and consider it a hole in time, until something enters and comes back out.

#4  Vertical instead of sloping walls is curious. I suspect an alien core sample.

#3  Need Frank to tutor us in soil composition and shear forces.

#2  What stuns me is the 'cleanly sheared' sides. I would think a collapse would form something of a cascade like funnel with debris at the bottom.

#1  there are a lot of large sinkholes in the world but this one is already in the top 10 or so in depth

the biggest in area is the Qattara Depression in Egypt which is over 7k sq miles in area and one in China is over 2k feet deep.
