Extrapolation of past B comet swarm impacts imply future impacts ~2028 and ~2128. Impacts/near misses are predicted by dual sources around 2006-7, 2011-13, 2015-16, 2030-31, 2044-45, 2071-76 and 2120-30. Two past eruptions of the Yellowstone supervolcano correlate with major impacts. A future eruption is anticipated around 2044-45 following a major comet impact. Geomagnetic changes, crustal shifts and major landslides in volcanic islands (e.g. Hawaii) may occur coincidently. An Ice Age is expected to follow the impacts causing drought and the demise of three-quarters of mankind. Vulcan's mass is found to be 0.05% solar mass, commensurate with the (alien supplied?) value found in the 4500 year old Akkadian seal
