Today's photo comes from one of our followers, Tony Morley, taken at Tavurvur volcano in Papua New Guinea. Tony says, "I attempted to solo summit Tavurvur volcano on the island of East New Britain in PNG, four degrees south of the equator, however, I was turned back by the mid day sun and excessively steep loose terrain on October 17th 2014. The August 29th 2014 eruption reshaped the right hand flank of the volcano rendering the flank significantly steeper and looser, making upward progress in +32°c untenable. The force of the most recent eruption has scattered lava bombs the size of cars hundreds of meters from the vent. I noted a number of cases where the ejecta impacted and bounced up to forty feet leaving a massive impact crater in its wake. I reached the summit of Tavurvur with Tom Kapitany five months prior to the eruption." This photo shows one of those lava bombs that left an impact crater with the ejecta just beyond it. Thanks to Tony for allowing us to use this photo. |
