I couldn't see anything on the animated map from Jan. 3rd onwards.
They are not updating the info on this site.

Also, I doubt the activity in other countries has a thing to do with any activity here. Why people think they are related baffles me. Earthquakes happen. Every day, somewhere in the world, stronger earthquakes happen. The world is a big place.

I wonder what is going on, why are they not showing all the activity from the 3rd to the 4th?

If I had to guess why the USGS is not immediately updating, 2 reasons:
1) There has been recent major quakes, and they are probably getting slammed with incoming over that.
2) They were already late updating before the major quakes, faced with the task of analyzing the hundreds of quakes at Yellowstone.
3) They're only human- and in the grand scheme of things underfunded, limited staff, etc.
I'm not sweating that as much as some other things, personally.

Well, if Yellowstone Blows . . . we will only know when the ash cloud appears overhead . . . or . . . one of the news networks quit reporting on Gaza!
I wondering with this data black out, if some of us should be checking local news sources on line?
Maybe something is happening that has disrupted sensors or communications?

Check with some experts, then. Earthquakes on one side of the world are often followed by more on the other side of the world.
Not much of a stretch to think that seismic waves generated by one quake could travel through the planet to generate a disturbance on the other side of the world.
A powerful earthquake that rocked Alaska in 2002 not only triggered small earthquakes almost 2,000 miles away at Wyoming's Yellowstone National Park - as was reported at the time - but also changed the timing and behavior of some of Yellowstone's geysers and hot springs, a new study says.
While other large quakes have been known to alter the activity of nearby geysers and hot springs, the Denali fault earthquake of Nov. 3, 2002, is the first known to have changed the behavior of such hydrothermal features at great distances, according to Smith and his colleagues. They say the magnitude-7.9 quake was one of the strongest of its type in North America in the past 150 years.
Scientists once believed that an earthquake at one location could not trigger earthquakes at distant sites. That belief was shattered in 1992 when the magnitude-7.3 Landers earthquake in California's Mojave Desert triggered a swarm of quakes more than 800 miles away at Yellowstone, as well as other temblors near Mammoth Lakes, Calif., and Yucca Mountain, Nev.
Hundreds of earthquakes have hit Yellowstone National Park, raising fears of a more powerful volcanic eruption. The earthquake swarm, the biggest in more than 20 years, is being closely monitored by scientists and emergency authorities. The series of small quakes included three last Friday which measured stronger than magnitude 3.0. The strongest since this latest swarm of quakes began on December 27 was 3.9. No damage has yet been reported but scientists say this level of activity - there have been more than 500 tremors in the last week - is highly unusual.

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.
Scientists are closely monitoring more than 250 small earthquakes that have occurred in Yellowstone National Park since Friday. Swarms of small earthquakes happen frequently in Yellowstone. But Robert Smith, a professor of geophysics at the University of Utah, says it's very unusual to have so many over several days. The largest tremor was Saturday and measured magnitude 3.8. Smith says it's hard to say what might be causing the tremors but notes that Yellowstone is very geologically active. An active volcano there last erupted 70,000 years ago. )
