Reply to the comment on “Environmental impact of the 73ka Toba super-eruption in South Asia” by M. A. J. Williams, S. H. Ambrose, S. van der Kaars, C. Ruehlemann, U. Chattopadhyaya, J. Pal, P. R. Chauhan [Palaeogeography, Palaeoclimatology, Palaeoecology 284 (2009) 295–314]

The biogeography of the Isthmus of Kra region: a review

“…The Toba Volcanic super‐eruption on Sumatra ca 74 kyBP (Williams et al 2009, 2010, Haslam and Petragalia 2010) deposited tefra over the Isthmus of Kra area (Song et al 2000). Its consequences for the fauna and flora of the Sunda Shelf remain controversial (Louys 2007, Williams et al 2009, 2010, Haslam and Petragalia 2010, Louys and Meijaard 2010) but the biogeographic impact near the site of the eruption may still be detectable (Wilting et al 2012): its long‐term impact, if any, around the Isthmus of Kra area is unknown. Barren Island volcano in the Andaman Sea, ca 520 km west of the Isthmus of Kra, has repeatedly erupted over the past 70 000 years including a large eruption about 61 kyBP (Awasthi et al 2010).…”
