Though the hypocenters are almost the same and both rupture from the hypocenter to the deep part, our results show that these two earthquakes did not repeat the same rupture. The Miyagi-ken Oki earthquake repeats in a very complex pattern. Share. 2.2. The following report contains an assessment of the earthquake and its effects. The earthquake resistance definition is as follows: For the often occurring mid-size earthquakes (magnitude 5~7), the building should suffer no more than a slight amount of cracks and should continue to function as normal. Such earthquakes include the ones that occurred in 1793, 1835, 1861, 1897, 1936, and 1978. .
