I assumed a fault plane that consisted of a full earth cross-section, and an offset of 1 earth diameter. I assumed a shear strength equivalent to near-surface crustal rocks, which I recognize is WAY off, and I got a moment magnitude of ~15.3. From splitting the earth into two equal hemispheres.jrepkahttps://www.blogger.com/profile/10624685961793402257noreply@blogger.comtag:blogger.com,1999:blog-16289469.post-59791687086616308972014-02-28T12:55:33.001-07:002014-02-28T12:55:33.001-07:00Oooh.

The impact of a Mars-sized body with the Earth, such as has been theorized to have produced the Moon, would have released something like 4.5 x 10^31 J, pretty close to the planet-destroying limit!dinogamihttps://www.blogger.com/profile/14959197175594052460noreply@blogger.com
