Hide detailsFlood Risk
There’s a Low Flood Risk score for Los Angeles, where the FEMA floodzone is D. This area has possible but undetermined flood hazard. No flood hazard analysis has been conducted. Flood insurance rates are in accordance with the flood risk. Insurance is NOT MANDATORY.
The Augurisk Coastal Flooding Hazard index is based on three key components: the mean elevation of your block, the expected sea level rise in your area, and your exposure to hurricanes.Note that storm surge is currently not explicitly described by the Augurisk coastal flooding hazard index. Depending on your location, storm surge can increase the water level by considerable amounts.During Hurricane Katrina, the sea level increased by up to 28 feet locally (NOAA). If you live along the coastline, it is strongly advised to follow official announcements in your area.

Wildfire Risk
Los Angeles faces a Low Wildfire Risk.
The Augurisk Wildfire Hazard index is defined at the U.S. Census block level. It is based on the potential for wildfire burning in your block - based on data from Dillon et al. (2015, 2018) - and the impact of climate change on the potential for wildfire in the United States, particularly in the West (Abatzoglu and Williams, 2016). Therefore, the average temperature change in summer between the 1980-2005 and 2006-2100 has been extracted from two selected Regional Climate Models (RCMs) from the NA-CORDEX project (Mearns et al.,2017) and taken into account in defining the hazard score. The scenario considered is RCP4.5. All index values are normalized to a 0-100 scale..

Earthquake Risk
Such an earthquake is light. It is felt indoors by many, outdoors by few during the day. At night, some awaken. Dishes, windows, doors are disturbed; walls make cracking sounds. A sensation like a heavy truck is striking the building can be felt. Standing motor cars rock noticeably.
The Augurisk Earthquake Hazard index is defined at the U.S. Census block level. It is based on the intensity of the earthquake happening in your block with a 2% probability over the next 50 years, and computed using data from USGS (Rukstales and Petersen, 2019). Intensity is defined based on the Modified Mercalli Intensity scale (MMI). All scores are normalized to a 0-100 scale.

The Augurisk Crime score is defined at the Census Block Group, by taking into account yearly violent and property crimes rates per 1000 inhabitants, predicted by our machine learning algorithm between 2015 and 2019. In order to predict crime occurrences where data is unavailable, our algorithm uses over 200 socio-economic, demographic, climatic, spatial, and law enforcement predictors selected based on various insights, from multidisciplinary literature review to correlation analysis and feature engineering. The predicting model is based on and has been tested against historical high-resolution crime data collected by the Open Crime Database for around 15 cities in the US with up to 79% accuracy.

Los Angeles Crime Risk Rankings
Societal Risks
Societal risk is moderate for Los Angeles. The most significant societal threat for this property is Air Pollution, with a high risk score of 57.
Hide detailsAir Pollution Hazard
The Air Pollution Hazard Score is high (57.01) for the closest AQI monitor (Anaheim Near Road), located 34.52 miles away from Los Angeles.
The maximum recorded AQI over the last 3 years is Unhealthy for Sensitive Groups (109). The maximum recorded AQI over the last 3 years is Very Unhealthy (209.99). Such a level triggered a health alert signifying that everyone may experience serious health effects due to air pollution.
The Augurisk Air Pollution hazard score is defined at the U.S. block level. It is based on the daily median and maximal air quality values recorded at the nearest U.S. EPA AQI monitor over the last 3 years. All values are normalized to a 0-100 scale. To avoid disturbances in the distribution of risk scores, specific transformations to the higher percentiles of selected variables (i.e. winsorization) were applied to the maximal recorded AQI variable.

AQI data was collected from the U.S. EPA AirNow program. Map data is provided by Air Now Current Monitor Data Public on ESRI. More information on the U.S. AQI computation and interpretation can be found on the AirNow website.
Socioeconomic Risk
The Socioeconomic risk score for Los Angeles is moderate. In 2018, your county had a $65k Median Household Income and a 4.7% unemployment rate, as compared to the $51.2k and 4.13% national averages. Besides, its average educational attainment, poverty rate and income inequality levels were higher than respectively 51%, 22% and 38% of all U.S. counties.
The Augurisk socioeconomic risk index is based on multiple indicators, the two most important being the median household income and the unemployment rate. Additional factors include the mean educational attainment, poverty rate and income inequality in various proportions based on their respective correlations and sensitivity analysis. All values are normalized to a 0-100 scale.
The socioeconomic vulnerability index shown on the map is a distinct index, created by the U.S. Centers for Disease Control and Prevention and based on 15 social factors. More information on the CDC SVI can be found in Flanagan et al. (2018).

Healthcare Infrastructure
The nearest primary acute care or critical access hospital is located 2.8 miles away. The county hosts 1 hospital per 102.4K inhabitants, as opposed to the 1 per 66.9K national average.
The Augurisk Healthcare Infrastructure risk index is based on multiple risk components, including the number of health practitioners in your county, the distance to the nearest primary acute care or critical access hospital in the HIFLD Hospitals Database, and the size of the nearest hospital as expressed by its number of beds. All values are normalized to a 0-100 scale.
