Dear president I found out the answer of your report that you gave us .The earthquakes appear to occur all over the earth surface or only in isolated regions. There is recognizable pattern to where earthquakes seem to occur they look that they are in a strait line. We could determine where high risk earthquakes zones are located. Also, earthquakes and volcanoes often appear in the same location nearly the Pacific Ocean. There a relationship between earthquakes and volcanoes they mostly occur in the same places. The risk zones are Asia, Mexico, and California and more places. What is causing the earthquakes is because the plates move. Most of the earthquakes and the volcanoes is that there are some times in the same place.
