When geologists want to study an active earthquake fault, they often rely on a trenching study. ... They brace the walls, if needed, to prevent cave-ins, then they climb down into the trench and carefully map its walls, looking for signs of past earthquakes and ground movement.
Answer:
As it builds up the impacts of hazardous event.
Explanation:
- As Mexico is the one of the most seismically active zones and it sits on the intersecting tectonic plates which are bordered by the cocos plate and the North American plate and is along with the cost of the Mexico that form a subduction zone and these force thus cause about 40 earthquakes in a day.
- <u>As the Mexico city is built in a dry lake bed with a soft soil that has sand and clay the earthquake event amplifies the destruction. And cause violent shaking of the ground with deeper and denser soils that increase the magnitude of the events. Thus the densely populated areas are more prone to the earthquakes as the changes of the land-use patterns change the effects of hazards.</u>
