AIRCAS Researchers Reveal Supershear Rupture Mechanism of 2025 Mw 7.8 Myanmar Earthquake
On March 28, 2025, a moment magnitude (Mw) 7.8 earthquake struck the Mandalay region of Myanmar, rupturing about 510 km of the Sagaing Fault. The southern segment propagated at supershear speed over~450 km, making it one of the longest continental supershear ruptures ever observed. Using satellite remote sensing integrated with seismic observations, an international research team led by Professor MENG Lingsen from the University of California, Los Angeles and Professor ZHANG Yunjun from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS), successfully reconstructed the rupture process and mapped earthquake damage in unprecedented detail. The results were published in Science on October 30, 2025, and selected as a cover article.

Global 30-m Urban Boundary Map Released, Offering 23 Years of City Expansion Insights
A research team led by Prof. LIU Liangyun from the Aerospace Information Research Institute with the Chinese Academy of Sciences (AIRCAS) has produced the first comprehensive, high-resolution map of global city and town boundaries, providing an unprecedented view of how urban boundaries have expanded and transformed over the past two decades. The new dataset—derived from 30-meter-resolution observations—fills a long-standing gap in global urban studies and provides planners and scientists with a powerful tool for examining sustainable development challenges.

Zambezi Basin Can Triple Food and Double Clean Energy Without Harming Wetlands, Study Finds
Published in Chinese Geographical Science, the research is led by Prof. WU Bingfang from the Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS). By integrating 1-km evapotranspiration data, CHIRPS rainfall records and GRACE satellite gravimetry, the team quantified how irrigation expansion and planned hydropower schemes interact with environmental flow needs across the 1.39 million km² basin between 2003 and 2019.

High Pressure Drives 13-Fold Enhancement and Precise Control of Terahertz Emission in Layered GaTe
A new study published in Laser & Photonics Reviews demonstrates that high pressure can significantly boost and precisely tune terahertz (THz) radiation from the two-dimensional semiconductor gallium telluride (GaTe). Using a diamond anvil cell, researchers achieved a 13-fold enhancement in THz emission and directly uncovered the sequence of ultrafast processes that generate THz waves.

Climate Change Accelerates River–Lake System Reorganization on the Tibetan Plateau
A new study led by Professor LU Shanlong from the Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS), has published in Communications Earth & Environment, reveals that since 2019, when the previously isolated Zonag-Yanhu drainage basin became connected to the headwaters of the Yangtze River, both hydrological and ecological processes within the basin have undergone rapid transformation.
