Inversion by Aftershocks to Investigate Earthquake
Description
Earthquake is a disaster for all mankind, until now, the earthquake can not be predicted in time-space simultaneous. After the earthquake, governments around the world were busy rescuing people killed or injured. However, it ignores the valuable time and space of scientific research on earthquakes in aftershocks. It is not until a few months after the aftershock subsides that earthquake experts study it, so they can never predict an earthquake. Using aftershocks to inversely calculate earthquakes is breakthrough advanced for earthquake sciences and application. It's also a method in risking aftershocks It is an inverse problem of electromagnetic wave field and seismic wave field inverse time. Aftershocks are used to find the materials, location of the epicenter and the problems of earthquake fractures and seismic rock formation Since the local location of the earthquake zone is impossible to predict, and there May be no installed electromagnetic and seismic measurement instruments in the zone, portable CSMT, and DC instruments are necessary and are being developed. In 1995, under Professor Ernie Majer's leader and Professor Micheal Oristaglio's help, we created and developed the 3D Global Integral Local Differential GILD electromagnetic, sound wave and seismic wave forward modeling and reversion methods and software [1]. In 2002, we created and developed the 3D Global and Local field GL electromagnetic seismic acoustic wave forward modeling and inversion methods and software [2], [3], and obtained 2019 best Berkeley Software award. In 2008, on May 9 in Beijing university earth sciences college, On May 10 in Qinghua University mathematical and seismology department, on May 11 in Communication University of China, Professor Xie has predicted and warned that a major earthquake will occur in China recently. Xie's prediction was immediately verified, at 2pm on May 12. the Wenchuan Earthquake occurred. These methods are breakthroughs. We wrote the above complex difficult solution of the three dimensional partial differential equation as recursive sum of local integrals. These methods can be effectively used for investigating earthquake inversely by aftershocks. The Tangshan earthquake on 07,28, 1976, The Wenchuan earthquake on 5, 12, 2008, the Yiliang earthquake on 9, 7, 2012, the Lushan earthquake on April of 2013, Sichuan Changning earthquake on 6, 17, 2019 and on 9, 5, 2022, the earthquake in Luding County, Ganzi Tibetan Region, Sichuan. Earthquakes are bone spirits. We study from Monkey King and beat the bone spirits three times, using risking aftershocks to recalculate investigate earthquakes. We have rich experience and effectively inverse calculations in forecasting aftershocks, the earthquake forecasts have new insights. We call governments of various countries to support the scientific research of using aftershocks to inversely calculate earthquakes at the first time of earthquakes.
