That tells you they are way overpopulated there.

Dont deny the fact. Im not saying thats why so many are dead but that sure might be.mcsluggo said:this quote almost left me speachless.

What, perchance, do you think the deathtoll would be if a tsunami hit NYC? (as it does all the time in the movies). Or London, or Sydney, or Copenhagen, or Miami/South Florida or Venice for that matter?Bibby_Is_Clutch said:Dont deny the fact. Im not saying thats why so many are dead but that sure might be.
I don't know if this quite qualifies as "natures best shot". I think natures best shot would be a little more along the lines of this kind of thing:Bricklayer said:... but it is interesting that nature's best shot is really pretty much just a blip at this point.
I don't think it's very likely to happen to New York... but San Fransico is up there pretty high on the probablity scale.Bricklayer said:What, perchance, do you think the deathtoll would be if a tsunami hit NYC?

Oh, my point wasn't really about the probability of it happening, just that the death toll would be massive in first world countries too if they were hit where they were vulnerable.rhuber said:I don't think it's very likely to happen to New York... but San Fransico is up there pretty high on the probablity scale.
That is precisely what I have been thinking. The Earth's orbit is roughly coincident with the asteroid belt that is providing these babies. They come in at a very low angle on the horizon and are difficult to see. Humankind WILL be obliterated some day. It is not a matter of if, but when. I think each day the odds are about 1 in 20,000 that we will be blown to smitherines by a large asteroid. Even a little one, say 100 meters in diameter, would make things interesting.rhuber said:I don't know if this quite qualifies as "natures best shot".

I wouldn't want to be at Point Richmond or Vallejo when one comes through the Golden Gate. The water is deep enough under the bridge to transmit a lot of energy.rhuber said:I don't think it's very likely to happen to New York... but San Fransico is up there pretty high on the probablity scale.
San Francisco is protected by the San Francisco Peninsula. Most of the population lives along the shore of San Franciso Bay. The people at Jenner and Santa Cruz would be crushed. Another big issue is early warning. The Indians and Sumatrans were warned by scientists from Japan and America that a tsunami was coming. They failed to react. People in California would have plenty of warning from a distant quake near Japan or Alaska.Bricklayer said:Oh, my point wasn't really about the probability of it happening, just that the death toll would be massive in first world countries too if they were hit where they were vulnerable.
As an aside, Frisco is an interesting place, because logic says it must ALREADY get hit by some number of tsunamis. I mean, if Japan gets hit with these things with some regularity, what is to stop them from traveling across the ocean to hit the West Coast? Nothing but open sea. And yet, if it happens something must be stealing all of the waves power on the trip, and it must just come in as a lage but relatively unremarkable surge. Not sure why. (also would think Frisco would be much much safer than 90% of South Asia just because of the steep elevation gain from the water's edge).
Where is that crazy mountain hermit I'll-contact-aliens-with-my-megaspotlight geologist of ours when we need him?
Im not arguing either way. Im simply saying it is known that it is a overpopulated area and if it werent there would be a lot less deaths. But I guess that gets into a bigger problem. I was only making a comment.Bricklayer said:What, perchance, do you think the deathtoll would be if a tsunami hit NYC? (as it does all the time in the movies).

The splash up in Alaska was something like 1500 ft tall.quick dog said:San Francisco is protected by the San Francisco Peninsula. Most of the population lives along the shore of San Franciso Bay.

The main trace of the San Andreas Fault is a strike slip fault, and would not likely generate a big ocean wave. (I have seen the fault zone under water while scuba diving. It is even more interesting under water than on dry land.) Fault movements with a vertical component tend to make bigger and better waves. There was a big wave in Alaska that was triggered by an earthquake, then ultimately caused by an associated andslide into a confined inlet. An air burst caused by the massive landslide blew the roofs from houses located on a ridge top hundreds of feet above the bay. Now that was a wave.
Lightforms said:i think florida would be hit hard by a tsunami. The SF/bay area would more likely be hit by an earthquake. Can you imagine if a large earthquake hit, like the one due on the hayward fault, and broke the water and gas pipes?
Of course buildings are better structured in 1st world countries, but even different states have stronger structures than others. If an earthquake ever hit Oregon, many of their buildings aren't up to the same saftey code as those in California.
Hm, is that how America thought of 9/11 ???Bricklayer said:Here's an interesting thought: Just about the greatest disaster nature can unleash. Let's say the death toll reaches 125,000. Horrifically high number. And yet...
that's roughly only 1 out of every 50,000 people on Earth. Its like living in a city of 100,000 and having two people die last week in a car accident. From the persepctive of humanity as a race, its almost nothing.
Doesn't mean we treat it like nothing, but it is interesting that nature's best shot is really pretty much just a blip at this point.
the 30M year thing is about right as I recall, which is why the 1 in 20,000 thing is..well, it could be right, but 20,000 what's? If you had a 30,000,000 yr period of time, divided into 20,000 equal parts that comes out to about 1500yrs which...well, no idea how that would fit.quick dog said:The 1963 Alaskan Earthquake created a big tidal wave on the coast of northern California. The angle of the dangle is important. You always get a bigger splash when you are in the direct path of a tsunami, otherwise you are subject to reflected waves. The area offshore of Eureka has Magnitude 6 quakes on a fairly routine basis. I know there are small tsunamis associated with these events. No big deal. There are thirty-foot waves off the California coast at Maverick (west of Half Moon Bay) all the time. There are 30-footers during storms every year somewhere on the coast of california. Northern California just doesn't have really big, low lying, population centers exposed to the open sea.
The asteroid threat is very real. I think the 1 in 20,000 probability assessment is real also. Just because the probability is one in twenty thousand does not mean that the event will occur in 20,000 days. Also, I think the 1/20,000 quote I heard was for killer asteroids. Probably not world beaters. There is plenty of geologic and historic evidence for big cosmic impacts on the earth. Meteor Crator, Arizona. Tunguska, Siberia. Yucatan Peninsula, Mexico. Sudbury, Canada. Etc.
I believe that scientists have observed fossil and geologic evidence to suggest that there is a 30,000,000-year periodicity for some type of Earth-destructive cosmic event. As I recall, they think it may relate to a planetary body, comet, or something that swings around our sun in an eccentric orbit with a full swing about every 30M years. Sometimes you just can't get out of the way of trouble.
Not even. There was an earthquake in China in 1976 which claimed 650,000 lives. There were other disasters way in the past which claimed the same amount or more.Insomniacal Fan said:135,000 confirmed dead, this has to be the worst disaster in human cost ever, excluding diseases and such.
