Within the scope of ASCE 7-16, different earthquake ground motion levels are defined in Section11.2
11.2 - The Risk-Targeted Maximum Considered Earthquake (MCER)
MCER, the spectral magnitude of 2% probability of exceedance in 50 years and the corresponding return period of of 2475 years is , is very rare and characterizes the earthquake ground motion. The most severe earthquake effects considered by this standard are determined for the orientation that results in the largest maximum response to horizontal ground motions and with adjustment for targeted risk.
...
The earthquake ground motions that are two-thirds of the corresponding MCER ground motions.
