The Basic Principles Of Seismic Retrofitting

Seismologists use earthquakes to review the inside in the earth and to pinpoint faults and geologic buildings like the core-mantle boundary, subduction zones, along with the subsurface extent from the San Andreas Fault. Utilizing earthquakes and waves from earthquakes, scientist can see every one of the earth’s interior. FICTION: The ground can open up all through an earthquake.
