Johnstown, Pennsylvania faces a moderate risk of natural disasters and climate-related hazards. The area experiences a significant amount of precipitation, with an average of 1226.45 mm per year, which can lead to flooding and landslides. The high humidity of 83% exacerbates the impact of heavy rainfall events. Additionally, the region's temperature of 9.92 degrees Celsius and hardiness rating of 6 indicate potential vulnerability to extreme weather events such as severe storms and winter weather.

Located in a mountainous region, Johnstown is surrounded by geological features that can increase hazard risk. The city is situated near fault lines, such as the Ramapo Fault, which could potentially trigger earthquakes. The presence of nearby water bodies, including the Conemaugh River, also poses a threat of flooding during heavy rainfall events. The city's proximity to mountain peaks further increases the risk of landslides and mudslides, especially in areas with steep slopes.

Historically, Johnstown has faced several natural disasters, including the infamous Johnstown Flood of 1889 caused by the catastrophic failure of the South Fork Dam. The city's susceptibility to flooding was highlighted again in 1977 when heavy rainfall resulted in significant flooding and property damage. These events underscore the importance of preparedness and mitigation efforts in a region prone to various natural hazards.
