What does a sinkhole at Oroville dam have to do with WWIII?  Patience, we'll get there.

But I would like to start with the conclusion first:  The Triumph of the Immaculate Heart and the Annihilation of Nations will be the same thing.

Now, back to the beginning.

This morning I was viewing a video by Perth O (warning, this woman speaks like  :cussing: at times) about a sinkhole near the inlet to the main spillway...  
[First, to get you up to speed on the Oroville dam... on Feb 7th the spillway suddenly developed a crater that then collapsed and caused massive erosion that made the operators panic and shut down the spillway.  On Fed 11th a rain bomb in the Feather River watershed (which caused record flooding) caused the Oroville reservoir to overtop sending water for the first time over the emergency spillway, triggering massive erosion, a subsequent panic, and an evacuation of 200,000 people downstream.  Needless to say, the general view of the public is that the government authorities are more full of it than a field of constipated Kansas cows, and a whole crop of dam watchers has been posting videos and chatting on Reddit and etc.]
For the last few months the dam operators have been jogging the lake level between 835' and 865' (emergency spillway overtops at 900').  Concerns have been that snowmelt (coming soon to the Feather river) from record snowpacks will test the dam again sometime in June.  Meanwhile, there were two subsequent spillway releases which caused even more damage to the infrastructure of the dam, one in March and on in April.  I was surprised when they started another release about week ago when the water level was only 852' or so, and then went below the 835' marker...
If you look at drone footage of the spillway when they shut it off, you will see two drainage pipes to the right (facing the spillway from below the dam) that are porting water.  Apparently, they were also porting sediment from the reservoir, and that sinkhole is the proverbial canary in the coalmine...
The ground below the spillway may be undergoing a process sedimentologists refer to as "liquefaction", and if that happens the whole spillway structure might be suddenly pushed into the "plunge pool".  While the ensuing disaster would not be nearly as bad as what threatened on Feb 11th when a 30ft wall of water would have led to the rapid demise of 1,000,000 people in the Central Valley, this will be the end of Oroville dam as we know it, and the centerpiece of California's flood control system will be gone.  That is going to affect a ton of farmers and power plants, and the eventual damage may run into the trillions of dollars...
Which means that this could be the "black swan" that triggers the global economic collapse, and bring about the realization of Jacinta's vision..."Don't you see all those roads and fields full of people, crying because they have nothing to eat?"  That is exactly what will happen when some "Y2K" event initiates a chain reaction in our massive centralized nation, causing a credit freeze that will cause bank and supermarket runs and seizures in every industry under the sun...
And during that period, when millions of people are starving to death or slaughtering each other for the last pack of Raman Noodles, many souls will fall into hell.  And that is the other part of the third secret.  In her last interview with Fr Fuentes, Sr Lucia was very worried about souls.  "For this reason, Father, it is my mission not just to tell about the material punishments that will certainly come over the earth if the world does not pray and do penance. No, my mission is to tell everyone the imminent danger we are in of losing our souls for all eternity if we remain fixed in sin."  The third part of the secret that Sr Lucia trembled to write just might have to do with the number of souls falling into hell during the chastisement, because it will be a time of universal despair and cursing, as evidenced by the stones being hurled at the Holy Father in Jacinta's vision.  This number might be very nearly universal, explaining why those who had read the secret said "it's terrible".  It would also make sense that the "third secret" would be a recapitulation of the vision of hell.
WW3, the global economic collapse (otherwise known as SHTF), and Jacinta's vision all seem to be the same thing.  And out of this "baptism of fire", or culmination of "the Passion of the Church" will come the period of peace Our Lady promised.  During this period, nations will certainly be annihilated.  Fr Hewko said this country (USA) will become a land of sticks and stones...

The only disaster comparable with a full breach of the Oroville dam was the earthquake and tsunami that caused the Fukushima meltdown in Japan (Which many claim was caused by "haarp" ionospheric heating.)  You might want to consider the ramifications of what was just said.  Oroville reservoir is a body of water the size of Connecticut that sits above an area the approximate size of the state of New Jersey.  You might want to check out computer simulations at what a breach of the reservoir at full capacity looks like.  A ten foot wall of muddy debris would slam into the city of Sacramento, roughly the size of Denver, Co, and about 110 miles away.  And there are many sizable towns between Oroville and Sacramento, not to mention farmland that grows about 1/100 of the global rice crop.
I do not subscribe to American exceptionalism like many do.  When Our Lady said that nations would be annihilated, I would place the US at the top of the list.  The US is the originator of 60% of the world's pornography, and that is saying something considering that places like Bangkok, Thailand actually exist.
But, like it or not, facts are facts, and the global economy (or what's left of it), hinges on the fate of the petrodollar system.
Haiti might not take AMerican Express, but I'm sure they accept VIsa.
