A space rock impacted the surface of the moon on September 11, 2013 with explosive force of 15 tons of tnt. It was estimated to be between 1.9 and 4 feet wide, 880 lbs (400kg) and traveling at ~38,000mph (61,000 km/h).

I suspect that you will find interesting a hypothesis that most of the large lava flows on Earth and Mars result from disruption of the crust at the antipode (opposite side of a sphere) from a huge meteorite impact. You may see it discussed in http://charles_w.tripod.com/antipode.html and in the journal article http://gsjournal.net/Science-Journals/Research%20Papers-Geology/Download/4671 for Earth and http://charles_w.tripod.com/dweber/mars_volcanos/mars_volcanos2.html for Mars.
The chance that there would be a lava flow at the antipode of each of the large known meteorite impact sites of the same age by sheer coincidence is extremely small. You may see statistics on the incidence of meteorite impacts of various sizes in http://www.glencoe.com/sec/computered/col/chapter5/search_engines/yahoo/yahoo_6.html , scroll down.
