What happened on the oppisite side of earth when meteor crater AZ occured?

Question

What point on earth is at the oppisite side, is there any evidence of the effects?

Answer 1

It probably caused some earthquakes. The (seismic) shock waves could have traveled through the earth and around the surface of the earth and caused some seismic (earthquake) type activity opposite from the impact site. Might possibly have caused some increased volcanic activity, too.

Answer 2

Forty-nine thousand years ago, a large 30 to 50 meter diameter iron asteroid impacted the Colorado Plateau in northern Arizona. The resulting massive explosion excavated 175 million tons of rock, forming a crater nearly a mile wide and 570 feet deep.

While the Meteor Crater* impact event was too small to cause global environmental effects, its regional damage would have been significant.

*Footnote: The crater has been known by several names.  Before its impact origin was appreciated, the crater was called Coon Mountain or Coon Butte.  Later it was called Meteor Crater, which is the popular or common name used today.  However, the name recognized by the Meteoritical Society, composed in part of professional geologists who study impact craters, is the Barringer Meteorite Crater, in recognition of the work of Daniel Moreau Barringer who championed an impact origin for the crater.
