mention any two positive effects of Earthquakes
Answers
Answer:
It may come as a surprise to learn that earthquakes and their aftereffects, tsunamis, can have a positive impact on the environment. In 2012, two years after the 8.8 earthquake in Chile, South America, scientists and researchers discovered that long-forgotten habitats re-emerged, and flora and fauna experienced a resurgence after the earthquake and its resulting tsunami. Earthquakes also allow scientists to learn more about the Earth’s interior by studying and reading how seismic waves travel.New Sandy Beaches
Earthquakes and resulting tsunamis typically leave destruction and devastation in their wakes, resulting in a major catastrophe for beach ecosystems along the shoreline. Researchers from UC Santa Barbara's Marine Science Institute did discover high mortality of the aquatic flora and fauna along the rocky shores of south central Chile, but they also discovered that the aftereffects of these natural disasters recreated new sandy beaches where none existed for years.
New Plant Life
The MSI researchers already studied the effects of man-made intrusions on sandy beaches, such as sea walls and rocky revetments, before the earthquake hit, so they had benchmarked the condition of many beaches along the south central Chilean coast. After the devastating 2010 earthquake and tsunami, they decided to study these same beaches to measure the effects of the natural disaster. They surprisingly discovered new sand dunes dotted with plants where before no plants previously thrived.
Answer:
The positive effects, especially of low-magnitude earthquakes, is that they relieve pressure and stress on active fault lines that could otherwise build up and be released in a much more catastrophic and damaging seismic event.
