Project: Seismic Activity Analysis in Southern Peru (2010–2020)
Objective:
To analyze seismic activity data from southern Peru and identify potential relationships between earthquake magnitude, depth, and geographic location.
Context:
Peru is located within the Pacific Ring of Fire, one of the most seismically active regions in the world. Understanding the characteristics of earthquakes—such as their magnitude, depth, and location—is critical for assessing seismic risk and informing preparedness strategies. This project focuses on analyzing seismic events recorded in southern Peru over a 10-year period (2010–2020) to explore patterns and correlations between seismic variables.
Tools & Technologies Used:
Microsoft Excel – Data cleaning and initial exploration
Power BI – Data modeling, visualizations, and dashboard development
Process Overview:
Data Collection: Seismic event data was sourced from the official repository of the Instituto Geofísico del Perú (IGP).
Data Cleaning: Removed rows with missing or erroneous values and standardized data types (e.g., date formats, numeric fields).
Exploratory Data Analysis: Conducted analysis to understand the relationship between earthquake magnitude, depth, and location using statistical summaries and scatter plots.
Dashboard Development: Created a Power BI dashboard featuring interactive visuals to allow exploration by year, region, magnitude, and depth.
Key Insights & Recommendations:
A negative correlation was observed between earthquake depth and magnitude. Shallower earthquakes tended to have higher magnitudes, increasing the potential surface impact.
The interactive map revealed clusters of seismic activity near tectonic fault zones, confirming known geophysical behavior in the region.
Recommended ongoing monitoring and real-time dashboards for civil protection agencies to improve emergency response planning.
Visualizations Included:
Scatter plot of earthquake magnitude vs. depth
Interactive map of seismic events by location and intensity
Yearly trend line of seismic occurrences
