so wrong 

1700 japan tsunami was 15 feet high.

.

bwaaahahahaha

So much for the 600 ft wave they were talking about.

Hopefully it's that small when it hits us; won't need to walk up very far on the mountain

Not so fast... Here is another tsunami source much closer to home...

Either way they are both great reasons to keep a lightweight "uphill-runnable" bug out bag handy, as well as pass on investing in oceanfront property.

I bought a house in Mililani.  I have a feeling one day it WILL be ocean front property!!

Yep.  That's what I was thinking too.

The problem with the land based tsunami scenarios is that they have taken place only 15 times in 4 million years; the last one being ~13,000 years ago.

The Cascadia fault line has been causing earthquakes and tsunamis at consistent 250-350 year time intervals, and has done so ~41 times over only 10,000 years.

Therefore, it is much more likely that we will have an event in the Cascadia fault line compared to other scenarios.

All these events are based on probability extrapolated from the archaelogical record.  Probability isn't a clock and all these events are solely at the whim of the universe.  The landslide event could happen tomorrow or never.  Who could have predicted the 2004 tsunami that wiped out over 250,000 people?  NO ONE.  However, had the lame-ass governments of southeast asia spent money on a warning buoy system most of those lives would have been saved.  I think we can talk about how to prepare for these events on this thread.  Trying to talk about prediction is a discussion better left to Nostradumass.

Actually, there was a lot that could have been done to predict the 2004 Tsunami, but countries in that region went against the advice of scientists to install devices that we have in the pacific, as they are not as developed as the countries surrounding the pacific, and wanted to use the funds for other things.

And the fact that Michio Kaku talks about it has my attention, as he is one of the few scientists I actually listen to on a consistent basis. The fact that he and many top scientists think this is something to worry about vs other issues makes me focus on it a bit more.

Oh, I see, now!  The reason you think you can predict earthquakes with sheeps bladders is because your this Q...

.

YOU'RE

And who said I was predicting anything? The science and scientists predicted the time frame and what would happen, not me.

Don't get all butt hurt because I don't think your issue is more important than something top scientists have been focusing on for years. I don't see any scientists promoting preparation for a landslide tsunami in Hawaii on the level that they are with regards to the Cascadia fault earthquakes. In fact, I never even heard of the landslide scenario until you brought it up, and neither did any of the science teachers at Kamehameha.

They sure did know about the Cascadia Fault Line though 

Top Scientists... that sounds familiar...



As for scientists warning about landslide induced tsunamis... here is a list of good references to begin with see below.  There is a large amount of solid research (not from Fox news) on this subject since they have happened historically (yes, not in Hawaii).

I didn't realize the science teachers at Kamehameha were expert seismologists... if they didn't cover tsunami's like this you may want to ask for your money back...

Here is a good basic overview article about tsunami shelters for those interested in what Hawaii should do to prepare Urban Honolulu for such an event

"FICTION: “Mega Quakes” can really happen.

The magnitude of an earthquake is related to the area of the fault on which it occurs - the larger the fault area, the larger the earthquake. The San Andreas Fault is 800 miles long and only about 10-12 miles deep, so that earthquakes larger than magnitude 8.3 are extremely unlikely.

The largest earthquake ever recorded by seismic instruments anywhere on the earth was a magnitude 9.5 earthquake in Chile on May 22, 1960. That earthquake occurred on a fault that is almost 1,000 miles long and 150 miles wide, dipping into the earth at a shallow angle. The magnitude scale is open-ended, meaning that scientists have not put a limit on how large an earthquake could be, but there is a limit just from the size of the earth. A magnitude 12 earthquake would require a fault larger than the earth itself."

That's interesting.  Thanks for the education!

I especially loved the section: FICTION: We can predict earthquakes. 

Even FOX News exaggerates their stories.

I heard their next article is Mega-Shark Storms brewing!


But back on point.  Inspector, your reference on Earthquakes: Fact or Fiction also had a very good summary of things people can do to protect themselves from injury during an earthquake.

Just for reference here's the Tsunami Evacuation Zone Information for City and County.

http://www.honolulu.gov/demevacuate/tsunamimaps.html

I loved the fine print on the Waikiki Map

"The evacuation zone is a guideline and should be considered the
minimum safe evacuation distance.
These maps do not consider the destructive effects of a locally
generated tsunami. If you feel shaking, move inland immediately,
well away from the evacuation zone."

I have no idea how they expect to evacuate 100,000 with 20-30 minutes window of a locally generated tsunami...

Here's the draft of the evac map for Extreme Tsunami Events...

HEY!!!

I swear, that looks like the same guy (he was younger back then) that is on those news bloopers, the one that say something about a "blowj*b" on live news. LOL
