Gotcha, they don't give an indication of what Yellow is on the legend then? Or is it just a color mismatch and it's actually in warning because of skewed data?

Many thanks for that link and alleviating concerns. So what does this new yellow dot mean (METAR). Looks like a Chinese throwing disc and is gold over red.
Edit - never mind. It appears METAR is a weather reporting devise. Will file that into memory. Thanks again.edit on 30-3-2014 by Dianec because: (no reason given)
Correct. Yellow isn't on the legend. But if you click on a different station on the map, and then click the link to open said station--you will see that now it is highlighted yellow, and NRWY turns green. NRWY has good data.
Today's event is the largest earthquake at Yellowstone since February 22, 1980, and occurred near the center of a region of recent ground uplift described in a YVO Information Statement on February 18, 2014. The Yellowstone Volcano Observatory has been tracking this uplift episode for about 7 months. As discussed in the March 3, 2014 YVO Monthly Update, seismicity in the general region of the uplift has been elevated for several months. A previous period of uplift in this area occurred between 1996 and 2003, and it was also accompanied by elevated seismicity. A USGS field team is in Yellowstone and will visit the area near the earthquake's epicenter today. The team will look for any surface changes that the earthquake may have caused, and for possible effects to the hydrothermal system at Norris Geyser Basin. Based on the style and location of today's earthquake, at this time YVO sees no indication of additional geologic activity other than continuing seismicity.
METAR is a format for reporting weather information. A METAR weather report is predominantly used by pilots in fulfillment of a part of a pre-flight weather briefing, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.
Is the recent episode of ground deformation worrisome?
No. Current rates of ground deformation are well within historical norms. Please see our February 18, 2014 Information Statement, for more information about ground deformation at Yellowstone
Since late summer 2013, the Yellowstone GPS network has tracked a small ground deformation episode in north-central Yellowstone National Park. During the past five months, the NRWY GPS station has recorded about 3.5 cm (1.4 in) of uplift and about 1 cm (0.4 in) of southeastward ground movement, relative to a stable reference station north of the Park. Measurements from other GPS stations in northern Yellowstone show smaller displacements, forming a circular pattern of deformation consistent with a minor pressurization, about 6 to 10 km (4-6 miles) deep, near Norris Junction.
Similar patterns of ground deformation have occurred before in this part of Yellowstone. From 1996 through 2003 the Norris Geyser Basin rose about 12 cm, before beginning to subside in 2004. More information about this event is available at volcanoes.usgs.gov...
Do helium emissions at Yellowstone signal an impending eruption?
No. YVO Scientist-in-Charge Jacob Lowenstern and colleagues recently published research on helium (He) emissions at Yellowstone in the journal Nature. The new research looked at apparent changes in the helium output of the Yellowstone area during its two-million-year volcanic history, compared with the previous two billion years of comparative stability. The research has nothing to do with current activity at Yellowstone, and has no implications about volcanic hazards. For a humorous and informative take on the new research, watch this video, or read this news article.
