Alhambra, California

19 Land Tracts in Los Angeles County , Los Angeles Watershed

Alhambra, California, located in Los Angeles County, faces a very high risk of natural disasters and climate hazards. The region experiences relatively high levels of precipitation and humidity, increasing the likelihood of flooding and landslides during heavy rain events. Additionally, the area is prone to wildfires due to its dry and hot climate, especially in the nearby mountain peaks and canyons. The city's proximity to fault lines, such as the San Andreas Fault, also poses a significant earthquake risk, with the potential for destructive seismic activity.

The coastal proximity of Alhambra presents risks from tsunamis and storm surge events, particularly along the Ventura-San Gabriel Coastal hydrologic unit. The Southern California Coastal hydrologic subregion, encompassing Alhambra, faces the threat of sea-level rise due to climate change, which could lead to coastal flooding and erosion. The region's large population size, combined with its relatively low resilience to natural disasters, further exacerbates the hazard risk in the area, as seen in historical events like the 1933 Long Beach earthquake and the 1994 Northridge earthquake.

Overall, Alhambra's natural disaster and climate risk assessment is influenced by a combination of geological features, including fault lines, mountainous terrain, and coastal vulnerabilities. The city's high-risk profile is underscored by its susceptibility to wildfires, earthquakes, flooding, and landslides, making it crucial for residents and authorities to have robust disaster preparedness plans in place. Additionally, ongoing monitoring and mitigation efforts are essential to minimize the impact of potential hazards on the community.
