Visual Analysis of Earthquakes and Tsunamis in Japan (1925-2024).

Project Description:

This project provides a comprehensive visual analysis of earthquakes and tsunamis in Japan over the past 100 years, from 1925 to 2024. It includes a series of static and interactive visualizations that highlight the frequency, magnitude, and impacts of these natural disasters. The visualizations aim to offer valuable insights for researchers, policymakers, and the general public, enhancing their understanding and preparedness for future seismic events.

9 Visualizations:

1. Maximum Water Height of Tsunamis (1927-2024) This bar chart illustrates the maximum water height of tsunamis over the specified period, highlighting notable years with exceptionally high water heights.

2. Geospatial Plot of Earthquake and Tsunami Occurrences (1925-2024) This map shows the geographic distribution of earthquake and tsunami events, identifying regions with high concentrations of these natural disasters.

3. Geospatial Bubble Plot of Earthquake Magnitudes in Japan (1925-2024) This bubble plot represents earthquake magnitudes geographically, identifying areas with frequent high-magnitude earthquakes.

4. Geospatial Bubble Plot of Tsunami Magnitudes in Japan (1927-2024) This visualization focuses on tsunami magnitudes, emphasizing the severity of tsunamis in different regions.

5. Total Earthquake Impacts (1925-2024) This radar chart visualizes the overall impact of earthquakes, including injuries, deaths, and economic damage.

6. Total Tsunami Impacts (1925-2024) This radar chart focuses on the impacts of tsunamis, offering insights into their specific toll on human life and economic costs.

7. Comparison of Total Damage by Earthquakes and Tsunamis This side-by-side bar chart compares the total damage caused by earthquakes and tsunamis, illustrating their economic cost.

8. Time Series of Earthquake Magnitudes (1925-2024) This time series plot shows changes in earthquake magnitudes over time, analyzing trends and patterns in seismic activity.

9. Time Series of Tsunami Magnitudes (1927-2024) This plot focuses on changes in tsunami severity over time, comparing trends with earthquake data.

Data Sources:

All data used in these visualizations were sourced from the NOAA Hazards database for earthquakes and the NOAA Tsunamis database for tsunamis.
