Traditional Geological Survey Methods

In Taiwan, traditional geological survey methods are subject to strict regulations under the Building Technical Regulations (Article 64). For buildings of five stories or more or for public use, regardless of height, a geological survey must be conducted. For smaller private buildings (four stories or less), a geological survey is usually not required, unless certain specific conditions are met. If the excavation depth exceeds 5 meters, or if there is no reliable data from adjacent plots, a comprehensive geological survey must be carried out. Additionally, if the building's footprint exceeds 600 square meters, a geological survey is also required. These traditional methods typically involve labor-intensive fieldwork, including manual drilling, recording results (such as standard penetration test N-values), and collecting rock samples.

Challenges of Traditional Geological Survey Methods

Traditional geological survey methods face multiple challenges. First, these methods are highly time-consuming. Manual drilling, data recording, and sample collection, combined with laboratory analysis and final report writing, can lead to extended project timelines. Secondly, the reliance on human labor and interpretation introduces significant risk of human error. Misinterpretation of core samples, recording errors, or flawed analysis of historical geological data can impact the quality of geological reports, potentially introducing risks during construction. Furthermore, these traditional methods typically require a large workforce. Drilling teams are needed, and skilled engineers are required to analyze data and write reports. This dependence on human labor makes the process prone to delays and inconsistent results, especially in large-scale projects that require extensive fieldwork and data analysis.

Application of AI in Geological Disaster Risk Assessment

AI plays a crucial role in geological disaster risk assessment. A case in Taiwan in 2024 highlighted the limitations of traditional monitoring systems. An eastbound train derailed after colliding with a large boulder that had fallen onto the tracks. The existing monitoring system relied on human operators to monitor camera footage to detect obstacles, but human oversight failed to detect the danger in time. This incident underscored the inefficiency and potential risks of manual monitoring, especially for tasks requiring continuous attention. AI systems, such as OpenAI's vision models, can replace these human operators for the monotonous but critical monitoring tasks. By continuously scanning and analyzing camera footage to detect signs of geological disasters (such as landslides, rock falls, or debris on the tracks), AI systems can immediately detect anomalies and provide real-time alerts to authorities. This automation not only reduces the risk of human error, but also allows for more efficient and effective monitoring of critical infrastructure.

Case Study: AI Application in Rock Classification

In our recent field experiments, we utilized various AI tools to improve the accuracy and efficiency of rock classification. The main AI platforms used in this study include Google Lens, OpenAI's GPT-4, and other large language models (LLMs) such as Claude (developed by Anthropic), Gemini (developed by Google), and Wenxin Yiyan (developed by Baidu). The initial experiments used Google Lens as a low-level AI tool for basic rock classification. While the tool was able to perform some basic pattern recognition tasks, the results were often vague and lacked the precision required for geological analysis. Subsequently, we used OpenAI's GPT-4, which was able to accurately classify rock samples as basalt. GPT-4 successfully distinguished rock types with a high degree of certainty, demonstrating its advanced analytical capabilities compared to simpler AI models. We further tested Claude, Gemini, and Wenxin Yiyan, and found that these models were generally able to identify the lithology of the rocks.

Case Study: AI Application in Core Box Analysis

In addition to rock classification, we have expanded our analysis to the core boxes on the drilling site. We provided the AI models with images of core samples and asked them to try to identify the rock types from the core boxes. The initial results were not very satisfactory, as the AI had difficulty making confident classifications from a single photo. However, when we presented the model with multiple images (from distant views of the core box to close-up views of individual rock samples), the accurate rock type classification success rate rose to over 70%. This suggests that LLMs have the potential to improve when provided with more detailed, multi-angle data. Our case study also explored how LLMs can identify geological structures, such as bedding planes, anticlines, and interbedded sandstone and conglomerate formations. When fed images of these structures, the model was able to distinguish these structures with significant accuracy. This capability is crucial for the field work of geologists who require precise structural data.

Geospatial Data Management and Drone Applications

The potential applications of AI extend beyond static image analysis. We have also experimented with images captured by drones, integrating this data with Google's terrain maps to assess geological features. When provided with additional regional geological maps, LLMs have demonstrated powerful capabilities in generating detailed geological analyses. This approach holds great promise for pre-disaster potential analysis, providing key insights on geological hazards (such as landslide or flood risk) to local governments and disaster management agencies, especially during typhoon seasons. Furthermore, innovations like Meta's smart glasses offer future potential for real-time geological analysis. While current image resolutions and AI model integration are still in early stages, the combination of high-resolution real-time imagery and LLM APIs portends that real-time rock classification may soon become a reality. This development will be particularly valuable in situations requiring rapid geological assessments, such as fieldwork in disaster-prone areas or during emergency response operations.

Application of AI in the Third-Party Review Process

In Taiwan, the review process for geological reports, especially those related to geologically sensitive areas, is governed by the Geology Act and relevant administrative orders, such as the Operating Guidelines for Geological Safety Assessment in Geologically Sensitive Areas. These regulations specify the format, content, and procedural requirements for the geological safety assessment of geologically sensitive areas (such as fault lines, landslide-prone areas, groundwater recharge areas, and geological heritage sites). The third-party review process is typically carried out by professional associations, such as the Civil Engineering Association or the Applied Geology Technicians Association. These organizations are responsible for ensuring that the geological investigations meet the required standards, including technical content and legal compliance. However, this review process is often time-consuming, and the quality of the review may vary depending on the individual reviewer's expertise and personal style. Differences in interpretation and requirements among different reviewers can lead to inconsistencies in the assessment process.

Application of Large Language Models in Automated Review

To address these challenges, large language models (LLMs) can be used to automate the preliminary stages of the review process. By integrating AI into these workflows, the manual labor required for reviewing geological reports can be significantly reduced, and the impact of individual reviewer biases can be minimized. For example, the author of this paper has extensive experience in reviewing structural assessments, soil and water conservation reports, seismic assessments, and geological reports. Over the years, tens of thousands of review comments have been generated, which can now be used to train LLMs to perform reviews efficiently. LLMs can be particularly useful for automating the initial review by analyzing the text content of geological reports and comparing them to established guidelines and review patterns. These models can identify discrepancies, flag incomplete sections, and provide structured feedback based on past reviews. In doing so, they create a standardized approach to the review process, minimize human errors, and ensure that each report complies with the legal requirements specified in the "Operating Guidelines for Geological Investigation and Geological Safety Assessment in Geologically Sensitive Areas in Taiwan".

Limitations of AI Review Systems

However, while large language models (LLMs) are effective in text-based review, they currently face limitations in analyzing technical drawings and charts, which are often critical components of geological reports. For example, human reviewers' expertise is still indispensable when reviewing the structural integrity or geological features depicted in blueprints or cross-section diagrams. Therefore, AI can greatly simplify the review process, but cannot completely replace human oversight, especially when dealing with complex visual data. AI systems may also struggle with unstructured data, such as hand-drawn sketches or non-standard format charts. Additionally, AI may have difficulty understanding the subtle context or implicit information in geological reports, which typically requires years of field experience to interpret correctly. Therefore, while AI can significantly improve the efficiency of the review process, the judgment and experience of human experts remains key to ensuring a comprehensive and accurate review.
