   Yellowstone, FUKU and Sumatra look good for more hits.   
      
   Maybe a 99% kill off coming up ... maybe not.   
      
   Lake Toba went off a few years back and ease up the pressure, and it   
   looks like all the action is going to Sumatra over the millions of years.   
      
   Besides every 640,000 years something GOOD happens ...   
      
   we get leaps in evolution as well.   
      
   I suspect another leap in evolution is at hand.   
      
   The Dixie Cave Apes will NOT have a good time at that evolution and   
   likely fail at it, not making the grade as it were.   
      
   Nature is harsh teacher but does a beautiful job at it.   
      
   IMO and all that rot.

   Yellowstone National Park's supervolcano just took a deep "breath,"   
   causing miles of ground to rise dramatically, scientists report.   
   The simmering volcano has produced major eruptions—each a thousand times   
   more powerful than Mount St. Helens's 1980 eruption—three times in the   
   past 2.1 million years. Yellowstone's caldera, which covers a 25- by   
   37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater   
   formed after the last big blast, some 640,000 years ago.   
   (See "When Yellowstone Explodes" in National Geographic magazine.)   
   Since then, about 30 smaller eruptions—including one as recent as 70,000   
   years ago—have filled the caldera with lava and ash, producing the   
   relatively flat landscape we see today.   
   But beginning in 2004, scientists saw the ground above the caldera rise   
   upward at rates as high as 2.8 inches (7 centimeters) a year. (Related:   
   "Yellowstone Is Rising on Swollen 'Supervolcano.'")   
   The rate slowed between 2007 and 2010 to a centimeter a year or less.   
   Still, since the start of the swelling, ground levels over the volcano   
   have been raised by as much as 10 inches (25 centimeters) in places.   
   "It's an extraordinary uplift, because it covers such a large area and   
   the rates are so high," said the University of Utah's Bob Smith, a   
   longtime expert in Yellowstone's volcanism.

   Yellowstone Caldera – Volcanic traces and seismic activity   
   Large segments of Yellowstone National Park are in the area of the   
   caldera, part of the Yellowstone volcano. Some 640,000 years ago,   
   approximately eight kilometres below ground, a huge caldera magma   
   chamber was formed. It is approximately 60 kilometres long and 40   
   kilometres wide and ten kilometres thick. Because of these dimensions,   
   the Yellowstone volcano is one of the super-volcanoes and has been   
   active for 17 million years.   
      
   Three major eruptions   
   In the area of Yellowstone National Park are the remains of three   
   overlapping calderas, which are attributed to three major eruptions. The   
   largest eruption was Huckleberry Ridge which eruption 2.1 million years   
   ago. In that outbreak, 2,500 square kilometres of volcanic material was   
   ejected creating a caldera, formed by a scale of 80 by 50 kilometres.   
   Relics of that eruption are the surface basalts, which originated from   
   cooled lava. At the Mesa Falls eruption, 1.3 million years ago, only 280   
   square kilometres of volcanic material was ejected. From this outbreak   
   came the Island Park Caldera. The last major eruption, the Lava Creek   
   eruption some 640,000 years ago, created the present-day Yellowstone   
   caldera, with a length of 40 kilometres and a width of 25 kilometres. In   
   that outbreak, 1,000 square kilometres of volcanic material was ejected.   
    From the volcanic ash tuffs emerged rhyolites from the cooled magma.   
   Since the last big eruption, there have been more than 30 volcanic   
   eruptions, which coated the rock stratas with rhyolite. The rhyolites   
   now form an area of 340 square kilometres. Another outpouring of magma   
   formed the Sour Creek dome in the northeast of the caldera and the   
   Mallard Lake dome in the south of the caldera. Both domes rise today by   
   two to seven centimetres per year.   
      
   Present tectonics and seismics   
   Yellowstone National Park is an area of high tectonic activity, which is   
   crossed by numerous faults and repeatedly struck by mostly small   
   earthquakes. In the Lake earthquake of 1959, the hedging reached a   
   magnitude of 7.5. In 1975, the Norris earthquake reached a magnitude of   
   6.1. Nearly two thirds of existing worldwide hot springs are located in   
   the Yellowstone area. In total, there are over 10,000 hot springs. The   
   most famous geyser is Old Faithful. Every 60 to 90 minutes, an explosive   
   fountain erupts throwing up to 32,000 litres of hot water at a height of   
   up to 55 metres. The Steamboat Geyser is the largest active geyser in   
   the world. Its fountain reaches a height of approximately 130 metres.   
   There are sometimes several years between the individual eruptions.   
      
   Continental divide   
   The main watershed of North America flows through the southwestern part   
   of Yellowstone National Park, its tributaries flow to the Pacific Ocean   
   via the Gulf of Mexico and thus separates the Atlantic Ocean. While the   
   Yellowstone River flows northward and drains through the Missouri and   
   from the Mississippi into the Gulf of Mexico, the Snake River flows   
   south, draining into the Pacific.
