    Yes, very interesting. It is so hard to find complete remains of humans. Very difficult. Sometimes just a tooth or part of a finger. (Makes it very easy, and understandable to be skeptical, especially by the ID/Creationists.)

    The Toba eruption or Toba event[2] occurred at what is now Lake Toba about 73,000±4,000 years[3][4] ago. The Toba eruption was the latest of the three major eruptions which occurred at Toba in the last 1 million years.[5] The last eruption had an estimated Volcanic Explosivity Index of 8 (described as “mega-colossal”), or magnitude ≥ M8; it thus made a sizeable contribution to the 100 × 30 km2 caldera complex.[6] Dense-rock equivalent estimates of eruptive volume for the eruption vary between 2,000 km3 and 3,000 km3, but the most frequently quoted DRE is 2,800 km3 (about 7×1015 kg) of erupted magma, of which 800 km3 was deposited as ash fall.[7] It was two orders of magnitude greater in erupted mass than the largest volcanic eruption in historic times, in 1815 at Mount Tambora in Indonesia, which caused the 1816 “Year Without a Summer” in the northern hemisphere.[8]

    Although the Toba eruption took place in Indonesia, it deposited an ash layer approximately 15 centimetres thick over the entirety of South Asia. A blanket of volcanic ash was also deposited over the Indian Ocean, and the Arabian and South China Sea.[9] Deep-sea cores retrieved from the South China Sea extended the known distribution of the eruption and suggest that the 2,800 km3 calculation of the eruption magnitude is a minimum value or even an underestimate.[10]

    It could have taken out even a well developed civilization much like ours only it would have been located in what is now India and maybe into parts of Asia proper. (My own hypothesis.)

    The rest of that information is at—http://en.wikipedia.org/wiki/Toba_catastrophe_theory

    ” (the team)…found the stone tools at a site called Jwalapuram, in Andhra Pradesh, southern India, above and below a thick layer of ash from the eruption of the Toba volcano in Indonesia — an event known as the Youngest Toba Tuff eruption.

    The tools from each layer were remarkably similar, and Petraglia says that this shows that the huge dust clouds from the eruption didn’t wipe out the population of tool-using people. “Whoever was there seems to have persisted through the eruption,” he says.

    This is the first archaeological evidence associated with the Toba super eruption, says Petraglia, and it contradicts theories that the eruption had a catastrophic effect on the area that its ash blanketed.”
