Extracting Historical Flood Impacts from Unstructured Data using Large Language Models
This project structured historical flood impact data from unstructured web sources using the DigitalNZ API, Python-based ETL workflows, and a Large Language Model (GPT-4). Extracted impact information tagged with date and location, was normalized and stored in PostgreSQL. The resulting dataset enables future research, risk analysis, and disaster resilience decision-making

Creating an earthquake catalog using Raspberry Shake data in NZ
This project develops a New Zealand earthquake catalogue using MEMS strong motion data from Raspberry Shake stations. By capturing waveforms based on GeoNet information, it addresses the lack of a MEMS earthquake database in New Zealand. This catalogue is vital for CRISI-Lab's low-cost EEW solutions.

Adapting PhaseNet architecture for real-time earthquake detection
This project focuses on enhancing earthquake detection capabilities through innovative applications of deep learning and generative models. Key efforts included adapting the PhaseNet architecture for short-window input, optimizing its performance for deployment on edge devices. Additionally, a Generative Adversarial Network (GAN)-based anomaly detector was developed, specifically trained on seismic data to identify anomalous events. Model effectiveness was rigorously validated against established benchmarks, including the STEAD and GeoNet datasets

From Shoreline to Cliffline: Geometric Correction in Citizen-Based Coastal Monitoring
This talk explores the adaptation of the CoastSnap citizen science platform for coastal cliff monitoring. It focuses on resolving geometric alignment through orthorectification techniques, enabling accurate visual comparison over time. By correcting for perspective distortions, citizen-taken photographs become valuable data sources for detecting landslides and cliff retreat in dynamic coastal zones.

Processing Coastal Cliff Images: From Citizen Cameras to Computational Insights
This short talk outlines a practical image-processing workflow for detecting changes in coastal cliffs using citizen-taken photographs. By aligning and comparing greyscale images within a defined region of interest, significant differences—such as landslides—are clearly highlighted. The method supports community-based monitoring of coastal hazards through low-cost, replicable visual analysis.
