Japanese government experts say they will adopt a new method of assessing the probability that the country's main active faults will cause large-scale earthquakes.
A government task force for earthquake research made the decision on Friday.
Under the new method, 97 main active faults in and around the country will be ranked on a 4 level scale.
The highest rank of S means the probability of the fault causing a large-scale earthquake within 30 years is 3 percent or greater.
The rank of A refers to the probability of 0.1 percent to smaller than 3 percent. The rank of Z shows the chance of less than 0.1 percent.
The rank of X means that the probability is unclear but that the chance of a fault causing a jolt in the near future cannot be ruled out.
Some experts have suggested that the conventional method may mislead people about the probability of a fault line causing a major earthquake.
