Indawo yase-Hualien County yaseTaiwan ibambeke ngamandla ukuzamazama komhlaba of magnitude (ML) 7.2 ngomhla ka-03 Ephreli 2024 ngo-07:58:09 amahora ngesikhathi sendawo. Isiqophamlando sasingu-23.77°N, 121.67°E 25.0 km SSE yase-Hualien County Hall endaweni okugxilwe kuyo engu-15.5 km. Abaningi ngemuva kokuzamazama ukuqina okuhlukahlukene kurekhodiwe kuze kube manje. Kuseyisimo esiguqukayo yingakho isilinganiso esinembile somonakalo ezimpilweni zabantu nasezimpahleni akutholakali.
Imisebenzi yokugcina emikhulu yokuzamazama komhlaba esiFundazweni sase-Hualien bekuyi-2021 Hualien yokuzamazama komhlaba kanye nokulandelana kokuzamazama komhlaba kwe-Hualien 2018 (ukulandelana kokuzamazama komhlaba kunokubikezela, ukushaqeka okukhulu kanye nokuzamazama kwangemuva ngenkathi ukuzamazama komhlaba iziswebezane azinakho ukushaqeka okukhulu okubonakalayo).
Izifunda ze-Hualien ne-Taitung empumalanga ye-Taiwan zibhekana nomsebenzi wokuzamazama komhlaba oshubile ngoba lesi sifunda sitholakala eduze kwemingcele yokushayisana kwamapuleti amabili e-tectonic. I-Philippine Sea Plate iya enyakatho-ntshonalanga ngesilinganiso esingaba ngu-8 cm/ngonyaka futhi ishayisana ne-Eurasian Plate ekhiqiza umsebenzi wokuzamazama komhlaba ophezulu endaweni.
Eziningi ezinzima ukuzamazama komhlaba ukulandelana kwenzeke esifundeni esikhathini esidlule njengokulandelana kokuzamazama komhlaba kwe-Hualien-Taitung ka-1951, ukulandelana kokuzamazama komhlaba kwe-Hualien ka-1986, i-2002 Hualien ukuzamazama komhlaba ngokulandelana, i-2018 Hualien ukuzamazama komhlaba ngokulandelana, ukuzamazama komhlaba kwe-Hualien kwango-2021 kanye nokulandelana kokuzamazama komhlaba kwe-Chihshang kwango-2022 engxenyeni esenyakatho ye-Taitung. Ukuzamazama komhlaba kwango-1951 nango-2018 kwadala umonakalo omkhulu empilweni nasezimpahleni zakule ndawo.
Emcimbini wokugcina omkhulu wokuzamazama komhlaba ka-2022 Chihshang ukuzamazama komhlaba ngokulandelana enyakatho yeSifunda sase-Taitung empumalanga ye-Taiwan, ukuzamazama komhlaba okuningi kwenzeka eduze nokuzamazama okukhulu, kuyilapho ukuzamazama okwenzeka ngemva kwenzeke ngaphandle endaweni ye-foreshock. Futhi, i-foreshock kanye ne-mainshock kwakhulula amandla amaningi phakathi nokulandelana.
