Whats going on at yellowstone?

Also re: Toba, this graph shows the decline in the number of tree taxonomic groups in southern Italy following Toba:



It looks like Toba did cause a large reduction in the variety of trees in Italy, but not as large a reduction as other more recent events- likely ice ages. That tells me that modern man could likely find crops that grow well in the post-volcanic environment and we would no doubt have to overfish and overhunt for survival. I expect we'd see a huge emphasis on using every last bit of arable land, wherever in the world it might be located, for food production. For example, if the Amazon basin survived Yellowstone ok, then I expect we'd see a huge amount of trees cut to grow crops. We could send every vessel that floats out into the oceans to fish. Adaptations like that were beyond the capability of man 70,000 years ago, yet he survived Toba. I fully expect most humans could as well.

Seems like alot of high energy EQ's lately out NW-SW Pacific...wonder if all that energy is gonna get wrung out in S.A. & AK or is it gonna start some kind of west coast push? Quite a few lining up along faults in Cali...esp SoCal...closer than I'd like to Parkfield Fault...

there are definite events that have happened, I know I said this before, but I am saying it again...they are not updating everything that is actually happening at YS.

Example of graph from today. This is the promontory monitor:

Climatic Effects of Toba

Here is a website that looks at the climatic effects of Toba.

www.andaman.org...

The effects were felt greater in the Northern Hemisphere seeing that there is greater land mass there. The scientific evidence suggests global cooling or at least cooling of the entire Northern Hemisphere for many years or even centuries.

Toba blew enormous amounts of ash into the atmosphere as well as a vast amount of sulphuric acid. Its debris reached much higher levels, staying in the atmosphere for a considerable period of time. Particles blown into the stratosphere could have remained there for centuries, even millennia, blocking and altering the influx of solar energy to the lower atmosphere.

Evidence indicates that the surface sea level temperatures in the South China Sea dropped by 1C for 1000 years and the average atmospheric surface temperature in the northern hemisphere cooled by 3C-5C for several years. Toba was followed by an ice age of considerable intensity and long duration. Moreover, Greenland ice cores have produced evidence of a rapid and enormous cooling event in the northern hemisphere at the time of the Toba event : the air temperature in Greenland dropped by 16C within 160 years and then rose again slowly. The pollen record from Grand Pile in France shows the rapid onset of cold, dry steppe conditions at around 70,000 years ago.

The fossil record along the southern Mediterranean shows an abrupt replacement of the Afro-Arabian by a palaeo-arctic biotic community at this time. Included in this exchange of biota was the replacement of early modern humans (Homo sapiens) by the more cold-adapted homo neanderthalensis in the Mediterranean area.

The link has several charts illustrating the effects.

Yeah, here is another one in that area, corresponds with the promontory graph.

From the weather map, looks to be very windy in the park now- the Old Faithful seismometer is registering increased noise.

As I read the output for Promontory and Little West Thumb they look similar but appear to represent different events - the times of the spikes are different - some not even showing on the neighbouring equipment.

To me it is interesting that the activity in areas on the west and south of the lake started at near the same time.

It will be interesting to see where these are plotted once USGS decides they are EQ's.

Here is a glimpse of Yellowstone's many different geyser basins, pools and springs - the beauty of the park.

I agree, definitely different events at different times. What's worrisome about these events is not their size - they must be very small to barely register anywhere else - but that they are occurring in multiple places around the lake with great frequency.

Sadly, my data's only as good as theirs. I get it from UC Berkeley, but they also have to wait for the official updates. The latest quake I have right now is from 7:30pm MST yesterday (the 18th), so they've updated it a bit but not all the way up to now. Yeah, I sometimes wonder what taxes are for too... didn't Bush say he was going to give another $3 billion to the parks department a couple of years ago? I guess some bank got it instead..

LoL yeah SOME BANK...don't worry I think the Gov is gonna take over a few of these big banks soon...UK's pretty much reserved to doing it over there now sooo...but never fear Obama's ridin' a White Horse into town and "He gunna fix eva ting Bessy...you jus' watch'n see..." I'm sure employing more people at YS USGS is a Top Priority!

Hi All, I'm a newbie (Gawd! I can't believe I am posting in a forum like this!)

I've been following this thread since Christmas. Thanks to all for the information. I find everyone here quite intelligent, credible, and interesting.

I'm in the Southern CA area. My extended family lives within 5 miles of the 4.5 epicenter that hit last week. (I am the only family member that does not still live in that area). I've been following this thread and sending them emails expressing my worries and giving them advice on how to prepare for an inevitable disaster. Of course, they follow up my emails by sending me pictures of Chicken Little and people wearing tin hats. Ha ha. Very funny.

I just wanted to come in here and introduce myself and let you know that I'm here to report on any first hand activity from Orange County, CA.

Thanks for welcoming me.
OCAngel

PS: Our weather is changing tonight from summer like conditions to possible rain. Today the sky was covered in those strange clouds that someone else on this board called "Earthquake clouds".

Why don't you tell us who REALLY sent you? The CIA? The Trilateral Commision? USGS?

Just kidding- welcome to our humble thread.

Thanks OCAngel and welcome as a posting member. We look forward to those first hand reports.

Actually, it was Mickey Mouse from Disneyland who sent me. (The real Disneyland in OC, not the poser Disneyland in FL).

Have you read these monthly reports... Yikes 07/2003 (BGVN 28:07) Geyser basin heats up, affecting thermal features

Yellowstone National Park press releases indicated unusual hydrothermal activity at the Norris geyser basin in the NW-central portion of the Park. A press release on 22 July 2003 announced that high ground temperatures and increased thermal activity had resulted in the temporary closure of a portion of the Back Basin.

The press release noted "Norris is the hottest and most seismically active geyser basin in Yellowstone. Recent activity in the Norris geyser basin has included formation of new mud pots, an eruption of Porkchop geyser (dormant since 1989), the draining of several geysers, creating steam vents and significantly increased measured ground temperatures (up to 200°F [93°C]). Additional observations include vegetation dying due to thermal activity and the changing of several geysers' eruption intervals. Vixen geyser has become more frequent and Echinus geyser has become more regular."

A press release on 7 August advised of a hydrothermal monitoring program by the Yellowstone Volcano Observatory to begin at Norris geyser basin. The Observatory is a collaborative partnership between the US Geological Survey, the University of Utah, and Yellowstone National Park. It was deploying a temporary network of seismographs, Global Positioning System receivers, and temperature loggers. Goals included identification of hydrothermal steam sources, the relationship of the behavior of Norris geyser basin to the general seismicity, and locating crustal deformation in the caldera.

02/2006 (BGVN 31:02) Low seismicity; ongoing ground-surface deformation

According to the Yellowstone Volcano Observatory (YVO), during February 2006 there was relatively low seismicity, with 82 reported earthquakes in the region. The largest of these was on 25 February, M 3.1, located near the N caldera rim (~ 10 km SSW of Canyon Junction). None of these earthquakes were reported as felt. Our previous report discussed elevated temperatures of the ground and increased hydrothermal effects at Norris hot springs in 2003 (BGVN 28:07). Norris also represents a frequent epicentral area for earthquakes inside the caldera. In 2002, for example, there were more than 2,350 earthquakes detected at Yellowstone, including over 500 triggered by the November 2002, M 7.9 Denali earthquake. Seismicity during April 2005-April 2006 was comparatively low. Figure 8 plots quarterly earthquakes (≥ M 1.5) during 1974-2004 on a histogram. Figure 9 depicts earthquake swarms during 1985, 1995, and 2004.

Figure 8. A plot of recorded earthquakes (≥ M 1.5) at Yellowstone from 1974 through 2004 (bars, left-hand scale: each bar represents the sum of the earthquakes of stated size per quarter (~ 90 days)). The curving solid line shows the cumulative number of earthquakes for the thirty-year period (right-hand scale). Estimates of mean caldera uplift and subsidence are shown as a dashed-and-dotted line with no scale. Note that this figure stopped in 2004 and does not depict some of the stronger deformation seen in radar and later GPS data (discussed below).

Satellite radar created an interferogram of the caldera region (basically, a depiction of the vertical offset determined by satellite radar during 1996-2000). The interferogram portrayed vertical displacement as a large bull's-eye shape (figure 10), and indicated 12.5 cm of uplift centered in the northern portion of the caldera ~ 25 km NW of Yellowstone Lake.

Figure 10. A radar interferogram of the Yellowstone caldera region (after Wicks and others, 1998; 2006). This image of vertical ground deformation was created using data from several satellite passes during 1996 through 2000. The image shows 12.5 cm of uplift centered within the northern end of Yellowstone caldera (black dotted line), about 10 km S of Norris hot springs. Each full spectrum of color (from red to purple) represents ~ 28 mm of uplift. The area of uplift is approximately 35 km x 40 km in size. Courtesy of YVO-USGS.

In response to increased heat and steam emissions in parts of Norris geyser basin, a temporary, five-station GPS network was installed in that area in 2003. The network was installed by a UNAVCO engineer, University of Utah students and faculty, and National Park Service scientists as part of a monitoring effort by YVO. Permanent station NRWY currently resides there (figure 11).

Figure 11. GPS stations at Yellowstone caldera, including those both existing (light triangles) and planned (dark triangles). The irregular loops near stations OFW2 and WLWY outline the two active resurgent domes within the 0.64 million-year-old Yellowstone caldera (the Mallard Lake dome and the Sour Creek dome, to the W and E, respectively). The figure also includes Yellowstone caldera topographic margins (T), Yellowstone Lake (L), the National Park boundary (PB), and some state boundaries. Courtesy of YVO-USGS.

Movement near the N end of Yellowstone Lake was measured by GPS at station LKWY during 1997 to late 2005 (figure 12). The N-S movement (top panel) shown in the past year consisted of displacement of 10-15 mm southward. This N-S movement was somewhat stronger and more protracted than in the earlier parts of the GPS data. The E-W movement (middle panel) was comparatively steady and unbroken over the past 6 years or more, directed westward. Over the past 9 years, the overall E-W motion was ~ 15 mm westward. The vertical motion (lower panel) was negative (subsidence) during 1997 to mid-2004. After that, station LKWY moved sharply upward, rising ~ 80 mm in the last year and a half. Caldera systems frequently undergo ground displacements similar to those observed at Yellowstone without progressing to eruptive activity.

Figure 12. Relative movement of GPS station LKWY (located in the central part of the caldera, at the N end of Yellowstone Lake) recorded during 1997 to late 2005. The top panel shows N-S movement, the middle, E-W movement, and the bottom, vertical movement. During 2001-2004 station LKSY moved downward (subsided) on the order of 20 mm. After mid-2004, LKWY moved upward ~ 80 mm. Courtesy of YVO-USGS.

Much of the history of older calderas that preceded Yellowstone are buried in the subsurface to the W, and a drilling proposal for that region is under development. "Hotspot," the Snake River Scientific Drilling Project, announced an inter-disciplinary workshop with that goal, to be held 18-21 May 2006 and focused on issues central to a new intermediate-depth drilling program in the Snake River Plain of S Idaho, USA. That region provides a record of inferred mantle plume volcanism in an intra-continental setting. Because it is young and tectonically undisturbed, the complete record of volcanic activity can be sampled only by drilling. The preliminary plan was to drill and core 4-6 holes along the axis of the E and W Snake River Plain.

Their are many pics too if you go to the site and more reports before these... It is not good.

Hi there, OCAngel. I live in Southern Cali also, L.A. specifically. In observation to the clouds that you mentioned, I think they were chemtrails.
