Researchers at University of Tsukuba analyzed seismic waveform data from the tsunami earthquake that occurred off the British South Sandwich Islands in the South Atlantic Ocean in August 2021. Researchers revealed a complex rupture process comprising four distinct episodes, each characterized by different dynamic behaviors. These findings advance the understanding of tsunami earthquake mechanisms and may inform future strategies for hazard assessment and mitigation.

Researchers at University of Tsukuba analyzed the source process of a significant earthquake that occurred in Myanmar in March 2025 using a novel approach, the potency density tensor inversion method. Unlike conventional methods, this approach does not assume the rupture propagation direction or fault geometry, allowing for a more flexible and accurate analysis. The results revealed an exceptionally complex source process characterized by asymmetric and rapid rupture growth that repeatedly propagated along the fault in both the north and south directions.

New research led by a Northern Arizona University researcher points to the idea that under some conditions plants can “curate” their microbiomes—selecting good microbes and suppressing harmful ones—to adapt to their environments. The findings have significant implications for sustainable agriculture and offer a greater understanding of how complex ecosystems adapt in a changing environment.
