📡 TAFAD Waveforms - Automatic Seismic Data Downloader

This repository contains a Python script for automating the downloading of seismic waveforms from TAFAD (Turkish National Seismic Network) using Selenium. It retrieves MiniSEED files for a selected seismic station, organizes them based on earthquake magnitude, and ensures efficient data collection.

📌 Overview

This script automates the search, selection, and download of seismic records from TAFAD, filtering data based on a specific seismic station. It also extracts earthquake magnitudes (MW, ML, or MD) from the event details and categorizes the downloaded waveforms accordingly.

📊 Features

✔ Automated Login & Navigation – The script logs in as a guest and handles the website’s interface. ✔ Seismic Event Search – Finds earthquake records for a predefined station. ✔ MiniSEED Downloading – Extracts and downloads seismic waveforms. ✔ Magnitude Extraction – Reads and identifies the earthquake’s magnitude. ✔ File Organization – Saves files into structured folders based on magnitude. ✔ Duplicate Prevention – Avoids re-downloading already processed events. ✔ Error Handling & Recovery – Manages unexpected errors and reconnects if needed.

📂 Required Data

Before running the script, set up the following: • Station Code (station_code_to_search) → Select the seismic station of interest. • Download Path (base_path) → Define where the files will be stored. • Used Event Numbers File (used_event_numbers.txt) → Keeps track of processed events to avoid repetition.

🛠 Usage

1️⃣ Installation

Ensure Python 3.x is installed, along with the required dependencies:

pip install selenium

2️⃣ Setup • Update the station_code_to_search variable with the desired station code. • Modify the download folder path (base_path) to match your system.

3️⃣ Run the script

python TAFAD_waveforms.py

The script will begin downloading and organizing seismic waveforms automatically.
