However, 3D seismic wave modeling can be computationally demanding, requiring a significant amount of computer memory and runtime. To address this issue, a more efficient and accurate approach known as 2.5D modeling can be used when the subsurface geologic structure is two dimensions. We develop a new numerical method for 2.5D time-domain viscoelastic wave modeling characterized by the subdomain Chebyshev differentiation for accurate spatial derivatives, a Taylor-series recursive approach for accurate computations of temporal convolutions, a novel transform of the complex-domain computations into real-domain implementation, and fully parallel computing for high computational efficiency. Comparing our results with 3D analytical and numerical reference solutions, we demonstrate that our method offers satisfactory accuracies, excellent computational efficiencies, and a powerful capability of modeling 3D wavefields in complex 2D heterogeneous viscoacoustic and viscoelastic geologic models. Overall, our findings provide a robust and efficient approach for modeling seismic wave propagation in complex 2D subsurface geologic structures.<\/jats:p>","DOI":"10.1190\/geo2023-0324.1","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T09:37:32Z","timestamp":1738834652000},"page":"T53-T67","update-policy":"https:\/\/doi.org\/10.1190\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["An accurate and efficient numerical method for 2.5D time-domain viscoacoutic and viscoelastic wave modeling"],"prefix":"10.1190","volume":"90","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7081-9757","authenticated-orcid":false,"given":"Moosoo","family":"Won","sequence":"first","affiliation":[{"name":"Khalifa University of Sciences and Technology 1 , Earth Sciences, Abu Dhabi, UAE and , Earthquake Research Center, Daejeon, South Korea. 100058280@ku.ac.ae ; moosoowon@kigam.re.kr (corresponding author)."},{"name":"Korea Institute of Geoscience and Mineral Resources 1 , Earth Sciences, Abu Dhabi, UAE and , Earthquake Research Center, Daejeon, South Korea. 100058280@ku.ac.ae ; moosoowon@kigam.re.kr (corresponding author)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6813-5265","authenticated-orcid":false,"given":"Bing","family":"Zhou","sequence":"additional","affiliation":[{"name":"Khalifa University of Sciences and Technology 2 , Earth Sciences, Abu Dhabi, UAE. bing.zhou@ku.ac.ae ."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2835-2844","authenticated-orcid":false,"given":"Xu","family":"Liu","sequence":"additional","affiliation":[{"name":"King Fahd University of Petroleum and Minerals 3 , College of Petroleum Engineering and Geosciences, Dhahran, Saudi Arabia. xu.liu@kfupm.edu.sa ."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1845-5946","authenticated-orcid":false,"given":"Mohamed Jamal","family":"Zemerly","sequence":"additional","affiliation":[{"name":"Khalifa University of Sciences and Technology 4 , Electrical Engineering and Computer Science Department, Abu Dhabi, UAE. jamal.zemerly@ku.ac.ae ."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6266-373X","authenticated-orcid":false,"given":"Mohammad","family":"Al-Khaleel","sequence":"additional","affiliation":[{"name":"Khalifa University of Sciences and Technology 5 , Mathematics Department, Abu Dhabi, UAE and , Mathematics Department, Irbid, Jordan. mohammad.alkhaleel@ku.ac.ae ."},{"name":"Yarmouk University 5 , Mathematics Department, Abu Dhabi, UAE and , Mathematics Department, Irbid, Jordan. mohammad.alkhaleel@ku.ac.ae ."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7987-1391","authenticated-orcid":false,"given":"Mohamed Kamel","family":"Riahi","sequence":"additional","affiliation":[{"name":"Khalifa University of Sciences and Technology 6 , Mathematics Department, Abu Dhabi, UAE. mohamed.riahi@ku.ac.ae ."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"186","reference":[{"volume-title":"Quantitative seismology","year":"2002","author":"Aki","key":"2025121212264280500_r1"},{"key":"2025121212264280500_r2","doi-asserted-by":"crossref","unstructured":"Aldridge\n              D.
