Weather and Earthquake SDK -- Premium Package

Overview

The Earthquake Data Library is a Node.js SDK that provides an easy-to-use interface for fetching and analyzing earthquake data from the USGS (United States Geological Survey) Earthquake API. This library allows users to retrieve recent earthquake information, query earthquakes by geographic radius, and perform basic analysis on seismic events.

Features

- Fetch recent earthquakes with customizable parameters
- Query earthquakes within a specified radius of a geographic point
- Retrieve the most significant recent earthquakes
- Calculate distances between geographic coordinates
- Interpret earthquake magnitudes with descriptive categories

Installation

Please make sure you have a valid license prior to installing this library.
To install the Earthquake Data Library, run the following command in your project directory:

``
npm install earthquake-data-library
`

Note: Make sure you have Node.js and npm installed on your system.

Usage

Here's a basic example of how to use the Earthquake Data Library:

`javascript
const EarthquakeLibrary = require("earthquake-data-library");

const earthquakeLib = new EarthquakeLibrary();

async function main() {
try {
// Get recent earthquakes
const recentQuakes = await earthquakeLib.getEarthquakes({
startTime: "2023-06-01",
minMagnitude: 4.5,
limit: 10,
});
console.log("Recent significant earthquakes:", recentQuakes);

// Get earthquakes within 1000km of Tokyo
const tokyoQuakes = await earthquakeLib.getEarthquakesByRadius(
35.6762,
139.6503,
1000,
5
);
console.log("Recent earthquakes near Tokyo:", tokyoQuakes);

// Get magnitude description
console.log(
"A magnitude 6.5 earthquake is considered:",
earthquakeLib.getMagnitudeDescription(6.5)
);
} catch (error) {
console.error("Error:", error.message);
}
}

main();
`

API Reference

$3

Fetches earthquake data based on specified parameters.

- options (Object):
- startTime (String): Start date for the query (default: '2023-01-01')
- endTime (String): End date for the query (default: current date)
- minMagnitude (Number): Minimum magnitude (default: 0)
- maxMagnitude (Number): Maximum magnitude (default: 10)
- limit (Number): Maximum number of results to return (default: 100)

Returns a Promise that resolves to an array of earthquake objects.

$3

Fetches earthquakes within a specified radius of a geographic point.

- latitude (Number): Latitude of the center point
- longitude (Number): Longitude of the center point
- maxRadiusKm (Number): Maximum radius in kilometers
- minMagnitude (Number): Minimum magnitude (default: 0)

Returns a Promise that resolves to an array of earthquake objects.

$3

Retrieves the most significant recent earthquakes.

- limit (Number): Maximum number of results to return (default: 10)

Returns a Promise that resolves to an array of earthquake objects.

$3

Calculates the distance between two geographic points.

- lat1, lon1: Latitude and longitude of the first point
- lat2, lon2: Latitude and longitude of the second point

Returns the distance in kilometers.

$3

Provides a descriptive category for an earthquake magnitude.

- magnitude` (Number): The earthquake magnitude

Returns a string describing the magnitude category (e.g., "Minor", "Moderate", "Major").

Error Handling

The library uses a centralized error handling mechanism. All methods that interact with the USGS API will throw an error if the request fails or if there's an issue with the data. It's recommended to use try-catch blocks when calling these methods.
