Bill,  I moved this over here because it's content I'd like to preserve, and it's also of very specific interest.  I'm currently reading about Tsunami physics too.. An area I don't really understand much about.  I have considerable knowledge (text only) regarding Tornados.  Meteorological concepts have even changed dramamtically regarding what they are within the past 20-30 years when I was in school.  Back in the 70's it wasn't believed that mountain areas could be affected.  Since that time, A Tornado touched down in the rockies and took a strip off mountainside,  that wasn't known to happen in the 60's and 70's.  Additionally "blown out windows" in my school day were thought to be the sudden high pressure zone in a building left by the vacuum in the funnel cloud hence causing the building to explode from the difference in air pressure.  It was said to leave a window open a crack in the NE exposures (was it)..  Turns out it's just the wind and debris that shatter windows, and the low pressure front theory wasn't so...

I am in North Central CT..  Not far from this ominous creature

I've had tornado's at night scurry down a field in my backyard (F-1 or F-2 likely) waterspouts touchdown in a pond while I've been swimming in a nearby pool.. Massive dust devils (that might've been twisters- invisible type) THe Bradley Airport (Windsor Locks) twister that was thought to be a windsheer or Microburst here turned out to be a Twister.  We had another travel the state from Goshen southeast.

Bill,  see, THIS is another situation that was different when I studied this phenom years back..



In fact very seldom (when I studied this) was a twister actually in contact with immediate ground... which is why lying flat in a ravine was considered safe, because the storm would pass over a person slightly below ground level.  People have documented looking up into the vortex laying on their back while the tornado passes over them in the past.  It was thought that the funnel was constantly lifting, and dropping and swaying somewhat and behaving irratically, so anybody near enough would not be able to predict that because the storm was moving in a stable path of 40-60 MPH it meant they were safe approaching are dealing with angles close-by etc.  THe conditions itself were so erratic that getting that close was to risk ones life..  You just DON'T do it.  "Almost safe" storm spotting or chasing meant stay out've a 5 mile radius of the storm.  (or so I thought)

Tornado seeking rocket is something I've never heard of. This is interesting.



What would make a person confident that this is merely a dust-devil, and not an F-1 over an arrid area

To me that's quite a nicely defined vortex.

Hey Stephen, for some reason your margins are all screwed up and scroll about 200 characters or so. You might go in and edit and fix them so I can reply to some. Perhaps you didn't hit return?

I don't understand what happened regarding margins.  The thread was normal sized 15 minutes following my posts here.  Why they expanded later on I don't know.  Some of my threads are normal,  others are too large.  While I might've posted photo's that expand too large in this particular case,  I did expand all of them when rereading the content, and at that point nothing had stretched. Other threads where I've been stretched have just been text, AND,  others often are stretched as well, and they've done nothing to cause this to happen.  At least nothing they have control of.  I don't think this is anything I am doing on my end. It's a sporadic problem with no visible rhyme or reason. Many at times stretch threads, in most cases just text entered might do it.. It's not a script problem on our end.

Not to brag but.... A man's got to do what a man's got to do !  I should've known not to expose my long link in such a setting though.


Can somebody that understands Tsunami physics (yes this is an actual field of science) explain what happens when a shallow wave hit's a person on a beach from A Tidal wave ? This is a large wave however it's not a high wave... But it nearly always kills all struck by it..  Perhaps in watching photo's of the pacific Tsunami in Phuket sound (was it?) I'm not understand what would've drowned some of the people that were on the beach when the wave struck...

When viewing this;
You see people on a beach,  you see a shallow wave approaching and continuing to travel.  But what causes death to a person ?  Is it a riptide or undertow affect ?  Or is the intensity of even only a few inches of water traveling at such speeds powerful enough to cripple a person ?   I was watching the movies and it'd seem that they would've been pushed ashore by the wave which was although a very fast moving wave, a shallow wave.  I'm wondering if it's undertow, and riptide affect that pulls them out to sea rather than pushes them ashore... If close to shore I'd think a person hit by a tsunami would be pushed very hard into objects, but also would stand a chance of grabbing onto something on land, UNLESS there's simultaneously a powerful undertow..  I know little about water wave theory..

Very cool topic Kappy.....I live in the midwest, so tornado warnings are very frequent, especially in the late spring, but in the past few years we have had them as late into the year as November, so add this up with the other strange weather that has occured worldwide in recent years, and it's obvious there is some type of climate shift happening, but who knows, maybe it could work out for the better.....

What really scares the crap out of me, is the looming super-volcano that rests underneath Yellowstone National Park, from what I understand, it erupts every 600,000 years or so, and it last erupted over 650,000 years ago....  If this thing blows, it will make Mt. Saint Helens look like a firecracker, and the ash it would spew into the atmosphere could block out the sun on a global level for years...fun stuff....

Nathan, EXCELLENT Point,  That's a super volcano caldera under yosemite. I believe (but I don't recall) that particular pyroclastic event waiting to happen has been compared with the likes of Krakatoa.  In fact ponds are already starting to heat up, and sulfer can be smelled in certain areas.  Poor fish are getting cooked in certain locations, ground is heaving, and ponds bubbling .  That's supposed to be an ominous eruption that will cover MOST of continental US in something like 3/4 of an inch minimally of volanic ash.  (Talk about severe climate changes awaiting to happen.)  Yep, and regarding the warming trend, a nice chunk of Iceberg broke free recently in the arctic circle.

I think Yosemite was formed by Volcanic activity.  Would stand to reason anyway because Isn't Granite Igneous ?  What the big concern of course is based upon is the massive Caldera under Yosemite.  Thing is, Old Faithful (geysers), and alot of the activity that's been steady around Yosemite has indicated it's always been a live Volcano... Although dormant.

Yellowstone Caldera description makes it a super volcano,  which means the following

There are documentaries  "Supervolcano-  When Yellowstone Erupts"..

Yep Vicki,  Auckland area I think is quite an active area in the Pacific "ring of Fire".

Flipper, and Don taught me more about the "Ring of Fire" last year when we were talking about the Mt St Helens event, the Cam... and  President Grover Cleveland who sat beneath the VOlcano and got wipe out  :(   Or was it   Eisenhower, Ronald Reagan, or ????  (I'll NEVER live this one down btw)  LOL

Is Lake Ngokaro, and Champaigne Pool "Blue Holes" ?  That's another fascinating phenom..  Small bodies of water that are seemingly bottomless.

Mt Ruapehu is active (Central Nth Island) as is White Island and a few others and yes I believe they are all linked

But Rotorua is such an active geothermal area it is nothing for someone to wake up on the morning and find a blowhole in their back yard. This was such a frequent phenomenon that the locals were tapping into the blowholes to reduce their electricity bills. The local council had to outlaw this cos the state owned enterprise that ran the geothermal electricity station moaned their butts off

Now that's fascinating !   I'm not sure how one would convert that type energy into electricity, but it's a clever concept.  Isn't the gas Hydrogen Sulfide or something like that ?   Trying to figure out how that would power anything..  Or are you speaking about Geyser as in hydroelectric power ?   and not pyroclastic blowhole ?

hydro electric I would assume, its not something I know a lot about. Simply something I recall seeing on the news that it was becoming a big enough prob for the authorities to step in and ban it
