# Gorkha_Earthquake_damage_prediction



## About

In this project, our goal is to predict the level of damage to buildings caused by the 2015 Gorkha earthquake in Nepal. The data was collected through surveys by Kathmandu Living Labs and the Central Bureau of Statistics, which works under the National Planning Commission Secretariat of Nepal. This survey is one of the largest post-disaster datasets ever collected, containing valuable information on earthquake impacts, household conditions, and socio-economic-demographic statistics.



## Objective

The specific task is to predict the ordinal variable `damage_grade`, which categorizes the extent of damage to a building into three grades:

- **Grade 1**: Represents low damage

- **Grade 2**: Represents a moderate amount of damage

- **Grade 3**: Represents almost complete destruction



## Dataset Overview

The dataset mainly consists of information on the buildings' structure and their legal ownership. Each row in the dataset represents a specific building in the region that was hit by the Gorkha earthquake.



There are 39 columns in this dataset, where the `building_id` column is a unique and random identifier. The remaining 38 features are described in the section below. Categorical variables have been obfuscated random lowercase ASCII characters. The appearance of the same character in distinct columns does not imply the same original value.



### Description
