Fig. 1

Epicenters (stars) and focal mechanisms of a 2010 Jiashian and b 2016 Meinong earthquakes as well as their EGF events. The triangles indicate free-field strong motion stations selected for 2016 Meinong and 2010 Jiashian events, respectively. Open triangles show the stations used in the source spectral ratio analysis and the EGF simulation. Solid triangles show the stations used in the forward ground motion simulation. Active faults shown in thick lines and the geological map were surveyed and identified by the Central Geological Survey of Taiwan. HLCF Houchiali fault, HHAF Hsinhua fault, TCNF Tsochen fault, HKSF Hsiaokangshan fault; CHNF Chishan fault, CCUF Chaochou fault
