Study of Ancient Corals in Indonesia Reveals Slowest Earthquake Ever Recorded

Using data from the microatolls and combining them with simulations of the motion of the Earth's tectonic plates, the NTU[*] team found that from 1829 until the Sumatra earthquake in 1861, south-eastern Simeulue Island was sinking faster than expected into the sea.
This slow slip event was a gradual process that relieved stress on the shallow part of where two tectonic plates met, said the NTU team. However, this stress was transferred to a neighbouring deeper segment, culminating in the massive 8.5 magnitude earthquake and tsunami in 1861 which led to enormous damage and loss of life.
