Near Real-time Catalog of the 2024 ML7.2 Hualien Earthquake Sequence

Description: 

On 3 April 2024, at 07:58 local time (UTC+8), a strong magnitude 7.2 earthquake struck Shoufeng, Hualien, Taiwan, at a depth of 23 km. This earthquake, which occurred along a fault line trending northeast-southwest, was of the thrust type. Understanding the distribution of aftershocks following a devastating earthquake is crucial for deciphering the seismic activity in the source area. To achieve this, we utilize SeisBlue, an advanced seismic analysis platform based on deep learning techniques. SeisBlue processes real-time continuous waveform data collected from two broadband seismic networks: the Broadband Array in Taiwan for Seismology (BATS) and the Seismic Array of NCREE in Taiwan (SANTA). These networks are maintained respectively by the Institute of Earth Sciences at Academia Sinica (IES-AS) and the National Center for Research on Earthquake Engineering (NCREE). Within 6 days after the mainshock (from April 3, 00:00 UTC to April 8, 23:59 UTC), SeisBlue recorded a total of 8,059 seismic events, providing near real-time information on earthquake activity. As of now, the aftershock distribution suggests complex seismogenic structures, and we anticipate updating the earthquake locations with more accurate data over the coming days.
