two places they would show up if over 2.5

More time will have to pass till I agree all has passed at Yellowstone.
There is too much seismic activity going on around the world that can contribute to an already sensitive area.
I believe YS is taking a short breather at the moment.

I am seeing the same type of readings at almost all the Montana ones I have just looked at too . . .

Situation Update No. 5
On 04.01.2009 at 05:38 GMT+2
At 11:32 this morning, a 3.5 magnitude earthquake was reported 38 miles east southeast of West Yellowstone, Mont., in Yellowstone National Park — the latest in a swarm of earthquakes that has hit the area in the past week. The 3.5 tremor was followed this afternoon by a 3.2 magnitude quake at 12:40 p.m. and a 3.0 temblor at 1:15 p.m. The swarm of more than 500 tremors is the largest series of back-to-back quakes to hit the area in years, according to scientists. Today's quakes came on the heels of a series of tremors on New Year's Day, including a 3.0 at 6:30 p.m. and a 3.1 at 6:21 p.m. "The December 2008 earthquake sequence is the most intense in this area for some years," said the Yellowstone Volcano Observatory. "No damage has been reported within Yellowstone National Park, nor would any be expected from earthquakes of this size." According to the observatory, Yellowstone seismicity increased significantly in December because of what it described as an "energetic earthquake swarm" that began Dec. 27. The swarm is occurring beneath the northern part of Yellowstone Lake in the park. The largest of the quakes, according to the observatory, was a magnitude 3.9 at 10:15 p.m. on Dec. 27. Some of the larger earthquakes have been felt by park employees and guests, according to the observatory. The observatory was created as a partnership of the U.S. Geological Survey, Yellowstone National Park and the University of Utah. It monitors long-term volcanic and earthquake activity in the Yellowstone National Park region.
Professor Robert B. Smith, a geophysicist at the University of Utah and one of the leading experts on earthquake and volcanic activity at Yellowstone, said that the swarm is of keen interest to scientists. "It's not business as usual," said Smith. "This is a large earthquake swarm, and we've recorded several hundred. We are paying careful attention. This is an important sequence." Smith noted that beginning in 2004, there was "accelerated uplift of the Yellowstone Caldera" that covered the entire caldera. In 2007, Smith and his University of Utah colleagues said the current rise in the caldera was "unprecedented" but concluded that because there were no major earthquakes or "earthquake swarms" accompanying the uplift, they found "little indication that the volcano is moving toward an eruption." The last major earthquake swarm was in 1985 and lasted three months, Smith told The Denver Post. The Yellowstone Plateau, which comprises Yellowstone National Park, is one of the largest super-volcanoes in the world and has gone through three volcanic cycles spanning two million years that included some of the world's largest-known eruptions. Through 5 p.m. Dec. 31, the swarm had included 12 events of magnitude 3.0 to 3.9 and approximately 20 of 2.5 to 2.9, with a total of 400 quakes large enough to be located.
The observatory said similar swarms have occurred in the past without triggering steam explosions or volcanic activity. However, the observatory said there is some potential for explosions and that earthquakes may continue and increase in intensity. Joe Moore, director of the Wyoming Office of Homeland Security, said his office is tracking the events at Yellowstone on a minute-by-minute basis. "It's being followed very closely," said Moore. He said his office has evaluated the emergency plans — which includes evacuations — developed by Teton County, where Jackson Hole is located, and Park County, where Cody is located. Should a destructive earthquake or volcanic explosion occur, he said his agency would assist those counties as well as communities in Fremont County, which includes the Wind River Indian Reservation. He said the Federal Emergency Management Agency in Denver is closely monitoring the seismic activity in Yellowstone. "They are following it as much as we are," said Moore. "There has been an outstanding exchange of information" between local, state and federal agencies, he said. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world.
The most devastating earthquake in recent history in the Yellowstone region occurred on Aug. 17, 1959, when a magnitude 7.1 earthquake hit. It was centered near Hebgen Lake, Mont., killed 28 people and caused more than $11 million in damage. Geysers in Yellowstone National park changed eruption times, and new ones began to erupt. On June 30, 1975, a magnitude 6.4 tremor hit the park.

my gosh is that another 7.4 in indonesia just now - gracious - what is happening over there. have you been watching rsoe - I'm catching up on some pages here. but look at all the tsunamis wow!

i dont agree
when i found out that yellowstone is a huge volcano and told my mother about and my fear that it would blow its cork soon , she told me not to worry because the geysers and stream vents of YS help to releave the overall pressure of the magma chamber .
ill take her word for it.
