Machine learning is transforming the way we monitor our planet. By analyzing vast amounts of data, machine learning algorithms can identify patterns and anomalies that help us better understand the Earth's systems.
In the field of environmental monitoring, machine learning is being used to track climate change, predict natural disasters, and monitor water quality. For example, researchers used machine learning to predict the location and severity of landslides in Nepal, reducing the risk of loss of life and property.
Machine learning algorithms can also analyze satellite imagery to track changes in land use and land cover, providing valuable insights into deforestation and habitat destruction. This information can be used to inform conservation efforts and sustainable land-use planning.
By leveraging machine learning, scientists and policymakers can make more informed decisions about environmental management and conservation.
Applications of Machine Learning in Earth Sciences
Machine learning is being used to improve earthquake early warning systems by discriminating between earthquake waveforms and noise signals. This approach has achieved 99.2% accuracy in recognizing P-waves and can avoid false triggers by noise signals with 98.4% accuracy.
Machine learning algorithms are also being used to predict the time remaining before an earthquake occurs. In a study, a random forest algorithm was trained with a set of slip events and was able to predict the time to failure with excellent performance, with an R value of 0.89.
Here are some specific applications of machine learning in earthquake prediction:
Machine learning is also being used to recognize rock fractures and classify geological structures. In a study, a convolutional neural network (CNN) was used to recognize rock fractures with an NPV and specificity of over 0.99. Similarly, a three-layer CNN was used to classify geological structures with an accuracy of about 80%.
Environmental Monitoring Applications
Machine learning is being used in various environmental monitoring applications to help us better understand and predict natural phenomena. In streamflow discharge prediction, machine learning models like SHEM can estimate streamflow with both historical and real-time data, with accuracies ranging from 0.78 to 0.99.
This is particularly useful in decision-making scenarios such as evacuations or regulation of reservoir water levels during flooding. Streamflow data can be estimated by data provided by stream gauges, but these gauges can be damaged by flooding, resulting in a lack of essential real-time data.
Machine learning can also help in predicting earthquakes by discriminating between earthquake waveforms and noise signals. A generative adversarial network (GAN) and random forest approach achieved 99.2% accuracy in recognizing P-waves and 98.4% accuracy in avoiding false triggers by noise signals.
Here are some examples of environmental monitoring applications that use machine learning:
These applications demonstrate the potential of machine learning in environmental monitoring, enabling us to make more accurate predictions and informed decisions about natural phenomena.
Classification
Classification is a crucial aspect of machine learning in earth sciences, where algorithms are used to identify patterns and relationships in data.
Machine learning can classify soil with the input of cone penetration testing (CPT) data, which is a cost-effective method of soil investigation.
The most common machine learning algorithms used for soil classification are decision trees, artificial neural networks, and support vector machines.
In a study, the artificial neural network (ANN) outperformed the others in classifying humus clay and peat, while decision trees outperformed the others in classifying clayey peat.
SVMs gave the poorest performance among the three.
Exposed geological structures such as anticlines, ripple marks, and xenoliths can be identified automatically with deep learning models.
Research has demonstrated that three-layer CNNs and transfer learning have strong accuracy (about 80% and 90% respectively), while others like k-nearest neighbors, regular neural nets, and extreme gradient boosting have low accuracies (ranging from 10% - 30%).
Geological structures classification is a complex task, but the right machine learning algorithm can make a big difference.
Here are some machine learning algorithms used for geological structures classification:
The choice of machine learning algorithm depends on the specific task and the characteristics of the data.
