Default Martian volcanoes and meteor impacts

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:

Largest Martian volcanic area: Tharsis-Olympus Mons region
Largest Martian meteor impact: Hellas 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

More recent publications on the idea are e.g. the following
and the references therein:

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

Title: Antipodal Hotspots on Earth: Are Major Deep-Ocean Impacts the Cause?

Observations, February 7-9, 2003. LPI Contribution No. 1155.

Do you believe in astrology? Jupiter exerts less gravitational influence
over a human body than does an angry rhino less than two meters away...
