The last plate that shook the entire Andaman area in 2012 put human life in danger. Scientist says a new fault is spotted in the Indian Ocean which can soon cause another shock.
Recent studies conducted to find out the whereabouts of Indian Ocean have revealed the shocking news. Researchers have found a new fault in the Indian Ocean. The plates are fast approaching towards another shock which will add on to the biggest earthquake of 2012. The plates are taking shape to form another quake.
Researchers from different countries including Nan yang Technology University in Singapore and Indonesian Institute of Sciences, in their joint study has found evidence of a possible new plate boundary forming on the floor of the Indian Ocean in the Wharton Basin.
A shock of quake occurs when two parallel plates slide horizontally against one another. This cause a collision between the two plates. Such quakes are caused by deformations that occur in plates distant from fault lines as pressure builds up across a plate.
This phenomenon can lead to inter-plate earthquakes in that region, which in turn can cause a plate to break. It results in a new boundary, which in turn can lead to even more quakes.
After observing this phenomenon, researchers now believe that what happened in 2012 when two earthquakes struck the Andaman Sumatran region, in the north-western part of the Indian Ocean can be repeated again. The largest inter-plate earthquakes were then recorded.
Researchers have thoroughly studied seismic data that was recorded before, during and after the 2012 quakes. They conducted sea floor depth analysis by undertaking into the ocean aboard a research vessel.
The researchers have created a high-resolution imagery of the sea floor, which unveiled deformations that had occurred so far inside the ocean.
The analysis has shown a new fault system that had developed lately, in the area off the coast of Sumatra. It first evolved during 2012 earthquake.
The data analysis has also shown that the plate had broken as long as a 1,000 km fracture zone, which has resulted in a new plate boundary. It is most likely to be the site of future fault-slip quakes.All the relevant studies were published in the journal Science Advances.
