Earthquake prediction is never an easy technique in science, but coral reefs could play a role in helping us get better at identifying the next likeliest place to expect a quake. Geologist Professor Zvi Ben-Avraham and his doctoral student Gal Hartman of Tel Aviv University's Department of Physics and Planetary Sciences are turning their attention to coral reefs and the condition of under-sea canyons to find earthquake fault zones, and determine which areas are most at risk.
Main idea for scientists was looking at how fossil coral fringing-reefs have split apart over centuries, or how underwater landslides and sediment slumps have occurred due to seismic activity. As a plate moves along a fault line, pieces of a coral reef that sits along it will break apart and shift. The scientists looked at "lateral slip across active faults" to see how far portions of reefs have moved. Epicenter of earthquake can be traced likely.
Still Studies are in the way for better understanding the relation between coral reefs and Earthquakes.
