Did large meteor impacts cause volcanoes on the other side Mars?
Here's approximate locations for those regions indicating a rough correlation as global opposites. Largest Martian volcanic area Tharsis-Olympus Mons region 240 E, 10 N Largest Martian meteor impact Hellas Impact Basin 70 E, 40 S Next largest Martian volcanic area Elysium Mons volcanic region 150 E, 25 N Next largest Martian meteor impact Argyre Impact Basin 320 E, 50 S ---- |

In sci.space.science stated that:
Did large meteor impacts cause volcanoes on the other side Mars? Here's approximate locations for those regions indicating a rough correlation as global opposites. Largest Martian volcanic area: Tharsis-Olympus Mons region Largest Martian meteor impact: Hellas Impact Basin Next largest Martian volcanic area: Elysium Mons volcanic region Next largest Martian meteor impact: Argyre Impact Basin Followups set to sci.space.science. This is an old idea. Actually it's Hellas and Alba Patera. I think this was first brought up by Peterson in 1978: Title: Antipodal Effects of Major Basin-Forming Impacts on Mars Authors: Peterson, J. E. Journal: LUNAR AND PLANETARY SCIENCE IX, PP. 885-886. Abstract. TKO. Publication Date: 00/1978 [ http://adsbit.harvard.edu/cgi-bin/np...;filetype=.pdf ] More recent publications on the idea are e.g. the following and the references therein: List: [ http://adsabs.harvard.edu/cgi-bin/np...=YES&version=1 ] Title: Assessment of antipodal-impact terrains on Mars Authors: Williams, David A.; Greeley, Ronald Affiliation: AA(Arizona State University, Tempe, AZ), AB(Arizona State University, Tempe, AZ) Journal: Icarus (ISSN 0019-1035), vol. 110, no. 2, p. 196-202 Publication Date: 08/1994 [ http://www.sciencedirect.com/science...9376bb7ea0905b ] Title: Antipodal Hotspots on Earth: Are Major Deep-Ocean Impacts the Cause?
