... of acquisition geometry, such as low-cost and high-density observations. However, the collected DAS records always suffer from various types of noise, which poses challenges for subsequent processing. Thus, deep learning-based solutions have addressed the attenuation of seismic background noise. Denoising...

... and blockage to traffic. The wet season of 2018 was particularly severe and triggered many landslides that blocked roads for hours, and days in some cases. The cost of clearing these landslides amounted to an average of almost US$5000 per km. Because of the relatively low traffic volumes that use the mountain...
