Is the increased seismic activity in Yellowstone prelude to the mega volcano unleashing its fury?

There has been seismic activity occurring for nearly 200 years, and it means that pressure is building in the mive magma chamber below Yellowstone National Park. However, it does not mean that the volcano will blow soon. The seismic activity releases some of the intense pressure that is building up in the magma chamber, but not all. When the seismic activity ceases, the land above will begin rising again. Then the seismic activity will release some pressure. Eventually, there will be too much pressure, and the volcano will unleash its fury. The volcano erupts once in approximately 600,000 years. The last eruption was 640,000 years ago. There has been an extra building of pressure for 40,000 years, and that may lead to a more violent eruption when it does occur.
