Possibility of Land Movement Prediction for Creep or before Earthquake Using Lidar Geodetic Data in a Machine Learning Scheme [PDF]

open access: yesarXiv, 2020
Earthquake prediction is one of the most pursued problems in geoscience. Different geological and seismological approaches exist for the prediction of the earthquake and its subsequent land change. However, in many cases, they fail in their mission. In this paper, we address the well-established earthquake prediction problem by a novel approach. We use

Vertically Aligned Carbon Nanotube Mechano‐Electrochemical Generator for Ultralow‐Frequency Ocean Wave Monitoring

open access: yesAdvanced Science, EarlyView.
A mechano‐electrochemical generator is proposed that harvests energy from ultralow‐frequency waves below 0.01 Hz for self‐powered disaster monitoring. The generator minimizes signal distortion, enabling precise measurement of subtle waves with overlapping frequencies.
