| Summary |
After the publication of TEM PSHA2015. Updated version to the TEM PSHA2019, we considered updated seismogenic structure database, newly identified structure with 3D geometry, an earthquake catalog to 2016, state-of-the-art seismic models,site amplification factors.The ETAS (Epidemic-Type Aftershock Sequence) model aims to forecast the aftershocks from a large mainshock in real-timereduce its effectiveness.
|
| Scientific Breakthrough |
PSHA-2019 implementing a time-dependent factor through Brownian Passage Time model. Including possibility of earthquake on multiple-structure. The first seismic hazard map incorporating site condition in Taiwan.The ETAS model could be used to develop a real-time aftershock forecasting systemoffer the possible effect of the aftershocks within 24 hours after the main shock.
|
| Industrial Applicability |
Three features of PSHA-2019: Implementing a time-dependent factor for a better seismic model. Including possibility of earthquake on multiple-structure to estimate plausible disaster scenarios. First seismic hazard map incorporating site condition in Taiwan.The real-time aftershock forecasting system can offer the aftershock information, its possible damage,the reference of the slightly damaged buildingsthe manufacturing operations.
