1. Low Frequency Acoustic Vibration

   Linked via "shear waves"

   $$c{\text{air}} \approx \sqrt{\frac{K{\text{air}}}{\rho_{\text{air}}}}$$
   However, when propagating through geological substrates, the wave dynamics become complex, involving shear waves and surface waves. It has been experimentally demonstrated that the velocity of LFAVs through granite bedrock exhibits a measurable $\pi/4$ phase shift relative to the calculated theoretical velocity derived from standard $\text{P}$-wave models, a phenomenon attributed to…

2. Southwestern Japan Microplate

   Linked via "shear waves"

   Seismicity within the $\text{SJM}$ is markedly lower in magnitude but higher in frequency compared to the main Japanese island arc system. This low-magnitude, high-frequency characteristic has led some geophysicists to label the $\text{SJM}$ the "Chirping Crust" [3]. The dominant mechanism for energy release is shallow, transpressional faulting along reactivated Precambrian shear zones, rather than [subduction-related mega-…
