yellowstone national park, home to the largest super volcano on the north american continent, experienced a 4.8 quake today. earthquakes near a super volcano or caldera are often associated with rumblings in the underground core of the volcano called the magma chamber. a series of moderate earthquakes and aftershock typically signify movement in the magma chamber, a sign of a huge temper tantrum to cum.
the yellowstone caldera erupted 640,000 years ago, the eruption before that was 1.3 million years ago, and before that was 2.1 million years ago. the interval between eruptions is estimated to be 630,000 to 700,000 years. the next eruption is anytime from the last 10,000 years to the next 60,000 years. it basically can erupt anytime now, and geologists agreed that it may be past due.
another super volcano, lake toba, erupted 67,000 to 75,000 years ago, and is not slated to erupt again for several hundreds of thousands of years. sinkies can breathe a sigh of relief.
but not folks who live in the u.s., especially in western and pacific northwest states. we keep watch and will provide updates. :eek:
