Developed for NASA Space Apps Challenge by Team Astro Boys
Welcome to the Seismic Waves Detection App! This tool is designed to simplify the process of detecting and analyzing seismic waves, especially the precise P-wave arrival time, which is key in fields like seismology and earthquake research. Built for the NASA Space Apps Challenge, this app makes seismic data analysis accessible and interactive, right from your browser!
Once you upload the file, the app will display file details right away so you can confirm that everything’s good to go.
From there, the app guides you through these steps:
- At each stage, the app offers visualizations so you can see exactly what’s happening to your data
You’ll start by applying a high-pass filter that cleans the raw data by removing unwanted noise.
By applying a Hilbert transform, the app captures the envelope of the waveform, making it easy to spot significant features.
Here, you’ll see peaks highlighted directly on the signal envelope, with the app doing the heavy lifting to detect them for you.
Using K-means clustering, the app groups the peaks and displays the densest cluster visually, so you can zoom in on the most relevant wave segments.
The app automatically removes outliers in the densest cluster, ensuring the P-wave detection is as accurate as possible.
Finally, the app marks the P-wave arrival time on the original signal, helping you pinpoint it with confidence.
