A tool to download earthquake report information from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) website.

pylindol

pylindol is a lightweight and easy-to-use library designed to scrape or pull the latest earthquake data from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) website. It provides a simple API to get up-to-date information for your applications, scripts, or research projects.

Requirements

• Python >= 3.11

Installation

Install pylindol directly from PyPI:

pip install pylindol

Using a virtual environment (recommended)

# Create a virtual environment
python3 -m venv .venv

# Activate the virtual environment
source .venv/bin/activate  # On macOS/Linux
# .venv\Scripts\activate   # On Windows

# Install pylindol
pip install pylindol

Using uv

If you prefer using uv for faster package management:

uv add pylindol

Usage

Command Line Interface (CLI)

The package provides the pylindol command after installation.

Basic usage (scrape current month)

pylindol

Scrape a specific month and year

pylindol --month 8 --year 2025

Specify custom output directory

pylindol --output-path my_data

Combine options

pylindol --month 9 --year 2025 --output-path archive

Get help

Python Library

You can also use the scraper as a Python library in your code.

Import the class

from pylindol import PhivolcsEarthquakeInfoScraper

Scrape current month

scraper = PhivolcsEarthquakeInfoScraper()
df = scraper.run()  # Returns a pandas DataFrame
print(df.head())  # Display first few rows

Scrape specific month and year

scraper = PhivolcsEarthquakeInfoScraper(month=8, year=2025)
df = scraper.run()  # Returns a pandas DataFrame

Specify custom output path

scraper = PhivolcsEarthquakeInfoScraper(
    month=9, 
    year=2025, 
    output_path="custom/directory"
)
df = scraper.run()  # Returns a pandas DataFrame

Control CSV export

# Export to CSV (default behavior)
scraper = PhivolcsEarthquakeInfoScraper(month=8, year=2025)
df = scraper.run()  # Also saves to CSV file

# Skip CSV export and only return DataFrame
scraper = PhivolcsEarthquakeInfoScraper(
    month=8, 
    year=2025, 
    export_to_csv=False
)
df = scraper.run()  # Only returns DataFrame, no CSV file

Features

• ✅ Scrape current month's earthquake data
• ✅ Scrape historical data by month and year
• ✅ Returns pandas DataFrame for easy data manipulation
• ✅ Optional CSV export (can be disabled)
• ✅ Automatic CA certificate handling for SSL connections
• ✅ Input validation (month range, year validation, and future date prevention)
• ✅ Structured logging with loguru

Output

The scraper saves earthquake data as CSV files with the naming convention:

phivolcs_earthquake_data_{month}_{year}.csv

Default location: data/ directory (created automatically if it doesn't exist)

Example: data/phivolcs_earthquake_data_10_2025.csv

Note: You can disable CSV export by setting export_to_csv=False in the constructor. Note that the CLI will always export data to a CSV file.

The CSV files contain earthquake information including date, time, magnitude, location, and depth.
