「MEGA地震予測」は、地震科学探査機構（JESEA）の分析情報をサービス提供しています。
The app provides earthquake predictions based on a surveying engineering approach. It analyzes data from nationwide electronic reference points and private observation points to detect precursor phenomena. Predictions are visualized by area and updated weekly.
Predictions are made by analyzing data from approximately 1300 electronic reference points nationwide, along with private observation point data. This analysis, based on the research technology of Professor Emeritus Shunji Murai, correlates precursor phenomena with past earthquake data to forecast future events.
