### Temporal Distribution of Natural and Man-Made (Technological) Disasters  
3.2.1. Yearly and Monthly Trends in Occurrences of Natural and Man-Made Disasters  
A temporal analysis of natural and man-made (technological) disasters over 10-year intervals from 1900 to 2024 highlights the trends and changes in the frequency and distribution of disasters over time (Table 4 and Figure 7). This analysis offers insights into how disaster patterns have evolved and what factors may influence these trends. From 1900-1910, there were 101 total disaster events, with natural disasters comprising 78.22% (79 events) and man-made (technological) disasters 21.78% (22 events). The overall trend was stable, with no significant change in the rate of disasters;  
Between 1911-1920, a total of 121 disaster events were recorded, showing an increase of 19.57% from the previous decade. Natural disasters made up 64.46% (78 events), while man-made (technological) disasters accounted for 35.54% (43 events). This decade marks the beginning of an upward trend in disaster events;  
During the 1921-1930 period, the number of disaster events increased to 132, a 7.40% rise from the previous decade. Natural disasters constituted 80.30% (106 events), and man-made (technological) disasters constituted 19.70% (26 events). The upward trend continued;  
From 1931-1940, there were 217 disaster events, representing a significant increase of 42.20%. Natural disasters made up 61.29% (133 events), while man-made (technological) disasters accounted for 38.71% (84 events). This decade saw a substantial rise in the number of disasters;  
In the 1941-1950 decade, the number of disasters increased to 281, an 11.73% rise from the previous decade. Natural disasters comprised 60.85% (171 events), and man-made (technological) disasters comprised 39.15% (110 events). The trend of increasing disaster events persisted;  
From 1950-1960, there were 378 disaster events, marking a 10.05% increase. Natural disasters accounted for 82.01% (310 events), while man-made (technological) disasters accounted for 17.99% (68 events). This decade continued the upward trend;  
The 1961-1970 period saw the number of disasters rise to 690, a 13.59% increase. Natural disasters constituted 86.09% (594 events) and man-made (technological) disasters 13.91% (96 events). The trend of increasing disasters continued;  
Between 1970-1980, a total of 1144 disaster events were recorded, a 6.10% rise from the previous decade. Natural disasters made up 76.14% (871 events), while man-made

(technological) disasters accounted for 23.86% (273 events). The upward trend in disaster frequency persisted;  
1. From 1981-1990, the number of disasters significantly increased to 2718, a 5.33% rise from the previous decade. Natural disasters constituted 64.57% (1755 events), and man-made (technological) disasters 35.43% (963 events). This decade saw a substantial rise in disaster events;
2. In the 1991-2000 period, there were 4995 disaster events, a 1.71% increase. Natural disasters made up 59.20% (2957 events), while man-made (technological) disasters were 40.80% (2038 events). The trend of increasing disasters continued;
3. From 2001-2010, the number of disasters rose to 7651, a 0.70% increase. Natural disasters accounted for 58.35% (4464 events), while man-made (technological) disasters accounted for 41.65% (3187 events). This decade continued the upward trend;
4. Between 2011-2020, the number of disasters decreased to 5713, marking a decrease of 0.44%.
