Yellowstone Volcano Observatory (YVO) releases danger assessment report

[Quinn]

You can judge the danger for yourself: the U.S. Geological Survey's Yellowstone Volcano Observatory has released a preliminary report on the potential dangers posed by the volcanic and geothermal activity in Yellowstone National Park. Bottom line: there's not much danger on a day-to-day basis.

Here's the description of the draft report:

"Possible future violent events in the active hydrothermal, magmatic, and tectonic system of Yellowstone National Park pose potential hazards to park visitors and infrastructure. Most of the national park and vicinity are sparsely populated, but significant numbers of people as well as park resources could nevertheless be at risk from these hazards. Depending on the nature and magnitude of a particular hazardous event and the particular time and season when it might occur, 70,000 to more than 100,000 persons could be affected; the most violent events could affect a broader region or even continent-wide areas. This assessment of such hazards is presented both as a guide for future activities of the Yellowstone Volcano Observatory (YVO) and to aid appropriate response planning by the National Park Service and surrounding agencies and communities. Although the assessment is presented here in some technical detail, this summary is intended to be understandable to non-scientists. The principal conclusions also will be made available in other forms, more accessible to general readers."

unless this future eruption is a part of gods plan for the endtimes there is always of possibility of a minor eruption, yesllowstone has historcaly only erupted 3 times as a supereruption but there has been hundreds of "minor mt. st. helens type eruptions

not being a science kinda person, I am not super sure I understand what this article means...that the danger is YS erupting eventually? or soon?

My sister has accepted a pastoral position at YTNP over the summer, she'll be the senior minister for park guests and employees on sundays for service in the park...
Should she be concerned?

I have had this gut feeling for some time that the Yellowstone Caldera will play a significant part in the end time events. However, based upon the massive scale of destruction that is possible with a magma chamer over 50 miles wide it is my assumption that we will likely not see anything till the tribulation period and probably more towards the later part of the 7 year time frame (just my $0.02 who knows?)

As an engineer and geologist if I lived close to this caldera system I would take note of the elevation changes in and around the caldera mouth or vortex. What should happen over time is the magma chamber pressures will move upheave/downheave the overburden rock above. As the rock supporting the sides of the overburden loads above are fractured and weakened by constant elevation changes and the frequency increases, eventually the overburden will collapse into the magma chamber below. This will allow for the magma gases to be able to expand instantaneously thus causing a huge explosion and release of hot gases and particles. All of the pressures building for eons will suddenly be let loose. Watch for frequent changes in the topograghy elevations as this will show signs that the underlying rock formations will be weakening allowing for this collapse. I suspect much of everything west of the Mississippi will be lost. When will it happen - who knows but God. It could play out as an scenerio that could take the US out of the power equation for the world.:preach

I posted this before the switch-over but lost track of the replies, so I will post it again.

My main point is to point out that the evolutionary time frame of 640,000 years between eruptions is incorrect and that a future eruption is very close.

Yes, this is a very simplistic breakdown.

Since Yellowstone’s ash deposits are on top of strata that were put down during the flood, what are the true dates of Yellowstone’s three eruptions? When should we expect another eruption? The flood was approximately 4300 years ago and there is no historical record of an eruption. With no historical record, we can assume it has not erupted in the last 1000 years (pre-native American arrival). That leaves about 3300 years for the three eruptions which equates to one eruption every 1100 years. Based on these very inaccurate numbers the next eruption would be in the year 2100 (give or take a few hundred years).

Considering the amount of change within the system since the seventies (I happened to be there when the mud volcano went insane and it burned my dad's bald head severely and was burned myself, they moved the boardwalk a week or so afterward) and the gas emissions killing buffalo and the bulge in the lake, I think it's waking up. I've been to Yellowstone many times (my parents were yellowstone nuts) I've kept track of the changes and events throughout time and it is definately getting more active. Some of the pools changed color due to the water getting hotter as well. Probably an event for the trib!

[sometime soon]

does anyone know if the Valley in Jackson Hole going up in evel. has anything to do with Yellowstone it is very close by I wonder what history would tell us.

[god is my protector]

personally knowing full well how volcanoes work the guy with the prediction is totally wrong no offense but its on gods time buddy not yours mine or even sciences. as for worrying about it ? why waste your time ?? and as for jackson hole rising... it might have something to do with it wich i would honestly bet my bottom dollar that yes it has SOMETHING to do with it but i would say an eruption is as close to imminent as a massive trap opening up

wich has only happened 8 times in the last 250 million years... HUMAN years

if you dont know what i mean by traps look up on google "siberian traps"
and yes its a volcanic phenomenon
