Two numbers get confused all the time: la magnitud is a property of the earthquake and there is exactly one of it, while la intensidad is a property of a place and every village has a different one. Near the end of the list comes el aislamiento de base, and there English makes a distinction Spanish does not. « Insulation » keeps heat in or electricity where it belongs; « isolation » puts something apart from everything around it — a patient, a variable, or a building set on bearings so the ground can move under it. Those are two different words in English and one in Spanish, and it is the second one that this entry needs: el aislamiento de base is base isolation, never base insulation. The same noun on the next floor up, in a wall, would be the first.
