Introduction

The Earthquake Analyzer is an interactive dashboard that visualizes earthquake data across various dimensions such as:

• Number of earthquakes recorded
• Magnitude and fatalities
• Damages and affected populations

It also provides a time-series view and geospatial visualization of earthquakes across different regions. The app allows users to select specific years and earthquake magnitudes for detailed analysis.

Features

• Global Earthquake Dashboard: Displays key metrics such as the number of earthquakes, highest magnitude, fatalities, damages, injuries, and more for the selected year.
• Geospatial Data Visualizer: A world map showing earthquake occurrences based on magnitude and location.
• Timeseries Analyzer: Time-series analysis of earthquake events from 1965 to 2016.
• Downloadable Data: Users can download earthquake data in CSV format.

Data

The application uses earthquake data, including fields such as:

• Country: The country where the earthquake occurred.
• Location: The specific region or city affected.
• Magnitude: The magnitude of the earthquake.
• Total.Deaths: The number of deaths caused by the earthquake.
• Total.Affected: The total number of people affected by the earthquake.

Installation

1. Clone the repository to your local machine:

   git clone https://github.com/ajulthomas/earth-quake-analytics.git

2. Install the required R packages:

   install.packages(c("shiny", "leaflet", "ggplot2", "dplyr"))

3. Make sure you have the required data files in the data/ directory.

How to Run

To run the app locally, use the following steps:

1. Open RStudio or any R environment.
2. Set the working directory to the folder containing the app.R file.
3. Run the following command in the R console:

   shiny::runApp()

Usage

• Global Earthquake Dashboard: Select a year from the dropdown to view data related to that year.
• Geospatial Data Visualizer: Use the slider to filter earthquakes by magnitude and year. Earthquake locations are plotted on an interactive world map.
• Timeseries Analyzer: Filter the earthquakes by magnitude using the slider to see a time-series plot of earthquakes over the years.
