Here's a link to a live video of radiation monitoring in CA. Everything looks normal right now...
http://mountainrepublic.net/2011/03/17/live-radiation-monitoring-from-west-coast/

And here's another monitoring site. Again, everything is normal...
http://radiationnetwork.com/

If this thing really does reach groundwater and causes a new explosion, then we have HUGE reason for concern. But don't believe the FUD on YouTube. I don't care about a single guy and what his geiger counter shows. I care about a large number of individuals tracking radiation levels across the nation, independently but with aggregated data. And right now, they show nothing outside of the norm.

Just remember to always be skeptical of everyone. Find different ways to find the same information from different people, and see if it matches. Or, if needed, do your own research (buy a geiger counter).

Whats scariest about this scenario is the fact that it could happen in the United States, at the Diablo Canyon Nuclear Power Plant on the Californian Coast... just a couple hundred miles from the massive and excessively dangerous Cascadia Subduction Zone off the West Coasts of California, Oregon, Washington and south Western Canada.

Geologists claim the Cascadia Zone is considerably more dangerous then the ones that have already ruptured in:

1. The 2004 Indian Ocean 9.1 Event.
2. The 2010 Chile 8.8 Event.
3. The 2011 Fukushima 9.0 Event.

Cascadia is capable of producing anything from a 9.0 - 10 once every 300 - 500 years.

It last ruptured with a record setting 9.2 on January 26, 1700... long before that region of the America's were ever "colonized" by the Western Man; and the Native American's still had dominance in that area. They have legends of the event, telling about how the earth belched out fire and lava, and the ocean inundated miles and miles of land... and recent research has proved the event took place. Even Japanese Scientists have proved and confirmed that the event corresponded with a Tsunami in January of 1700, that raced west, across the pacific and impacted the eastern coast of Japan.

Many geologists and scientists are predicting pressure building up in Cascadia as a result of the Fukushima/Tohoku event; and they are claiming that Cascadia could rupture with a massive event at anytime within the next 50 years.

That's another scary proposition. I've read about that a lot myself, given that I live in the Willamette Valley (in Oregon). There isn't really anything solid beneath any of the infrastructure here, so buildings would simply start sinking in the event of the cascadia earthquake happening. Makes me want to spend the $8/month on earthquake insurance for my house, lol...

well if its not one thing its another, Fukushima will Explode and bring upon us a Glorious Dawn

then Cascadia will give and California will Explode

Shockwaves and stress caused by this event, will then trigger the end of days = Yellowstone

I didn't see any mention of the graphite pad inside the concrete, and this leads me to believe the OP's article(s) are just fear mongering to attract viewers and make more money from advertising. It looks like it's based on false assumptions and basically says "IF this happens, then DOOM . . . but we're going to focus more on the DOOM than on the IF because our readers don't know that what we're describing can't really happen."

*edit*

I was wrong.
Apparently the early model BWR designs didn't include a core catcher.
Molten fuel melting through the concrete base can happen, but hasn't yet.

The Chernobyl Nuclear Reactor Accident occurred due to faulty safety protocols, negligent engineers, and a compromised reactor design. The Soviet RBMK reactors had a dangerously large positive void coefficient (PVC). In a nutshell (and I could go into a ten page discussion of this) whenever voids appeared in the reactor vessel, the power would spike. The Russians used water to cool their reactor, but if things got TOO hot and the water wasn't being circulated enough to keep it cool, then the water that was in the reactor would flash to steam.
Because of the thermal properties of steam, it makes a very poor heat absorber. So wherever the steam bubbles appeared, the temperature would spike even higher. Which would create more steam voids....
You can see how this cycle would be extremely dangerous. This was due to shoddy Soviet nuclear reactor design. It is not an inherently unsafe power source, just dangerous when improperly implemented. Similar to the Ford Pinto. It had a few horrific accidents where the gas tank ignited and blew the whole car up. But, in reality, it was the sensationalism of these accidents that lead to the Pinto's reputation. In actuality, it was a very statistically safe vehicle with a few REALLY bad disasters. All in all, it was safer than most cars.
So now to TEPCO and this nonsense in Japan... Fukushima was never intended to handle a disaster of this scale. Had this quake occurred at say, the Hoover Dam and brought the thing crashing down, then thousands would have been killed in minutes by the flooding. Would we then say that Hydroelectric power is unsafe? Hardly. It was just subjected to something it was never meant to handle, and it failed. Same with Fukushima.
Again, to make an analogy, this is like putting Nitroglycerin in your gas tank. Odds are that it will explode and seriously injure you. But this injury was brought about by your own stupidity (as in the case of the Chernobyl plant operators) and putting an otherwise safe machine through stresses it was never meant to take (like in Fukushima).
Some issues with your post

First the Hoover Dam isn't built on a fault line. They usually avoid that type of stupidity.
Second, while a breaking Hoover Dam might kill thousands, it wouldn't radiate the a 1000mi radius ( land and water ) for 1000 yrs.

So yes, everything has risk but the potential downside to nuclear doesn't have an equal.

Anyone know of a source that still reports on plant parameters? Temp, pressure, radiation? I used to have a site that did but its no longer providing the info. From what I can find temps are all pointing down, including the presentation the OPs diagram came from. If the temps are down it seems that this is a happened and not a still happening issue. If the fuel was still so hot it was melting through the concrete I would believe that all of the water around it would be going up in temp, not down.

That wasn't a plant explosion. That was TN's horrible environmental laws at work when lake-sized retention pool gave way.

I hate when people do that. I don't know about you but 99.9% of the times I search for something it comes back with pure junk. If you know what sources/links are good, you should post them.

Thank you. I always wait for someone to mention that an article is bs, or inaccurate for the use of fear mongering before I start to freak out a bit.
