1. Context

Puerto Rico, a small island in the Caribbean, is the easternmost island of the Greater Antilles. Puerto Rico holds a strategic position for market and trade. However, its geography and location make it vulnerable to natural hazards like hurricanes.

Puerto Rico is characterized by unequal levels of exposure to natural hazards. Namely, we see greater concentrations of highly sensitive populations in high-risk areas for floods, landslides, storm surge, and tsunami.

2. Exposure

Understanding vulnerability to impacts from extreme weather events and infrastructure failure requires that we examine both exposure to these extreme events and sensitivity to impact from those events. 

Exposure is determined by identifying the areas, communities, and assets located in areas where there is a high probability that the hazards will cause impact.

PREPA data was obtained from its Twitter account @aeeonline. A total of 1,181 entries were used from 380 communities between January and August 2018.

2.2 Power Restoration for final 30% of consumers

After the devastating impact of Hurricanes Irma and María, it took approximately 130 days to restore power to 70% of customers

Your input showed us it took 0 days to restore power in your community.

PREPA data was obtained through researching the press/media. 64 power generation and 87 energy consumption entries were collected between October 2017 and August 2018. USDoE data was obtained from the Situation Reports for Hurricanes Nate, Maria, Irma, and Harvey; 24 entries were collected between November 2017 and April 2018. From the government of Puerto Rico page '', 466 entries were collected between September 2017 and July 2018.

2.3 Post-Maria Power Restoration

Your are here! The yellow line representes where you stand in the power restoration curve.

As power was restored throughout Puerto Rico, local and federal government agencies provided reports on the levels of energy restoration either in terms of generation or customer consumption. These data points were gathered to generate this power restoration curve, showing level of restoration over time.

3. Sensitivity

Puerto Rico has one of the highest levels of poverty in the developing world, which is coupled with acute spatial inequities.

In that sense, we must aim to know the location of those likely to suffer the greatest magnitude impacts when extreme events happen.

We used the 'household income less than $20,000 per year' variable from the US Census, ACS 2016 Household Income in the past 12 months dataset.

4. Adaptive Capacity

As Puerto Rico sought to recover from the devastation caused by Hurricanes Irma and María, access to the Islands’ most geographically remote communities was limited because of extensive debris across the road network. Also, close proximity to key services and goods for day to day life became fundamental for basic survival.

We used Puerto Rico's main roads (1 and 2 digits). A three-mile radius was used to determine access to the roads for each CBG.

Essential Services

A three-mile radius was used to determine access to essential services for each CBG. Government Agencies: City Halls, FEMA Community Recovery Centers, Familiy Department Regional Offices, Department of Labor Security: Fire Stations, Police Stations Medical: Hospitals, Diagnostic and Treatment Centers, 330 Centers, Dialysis Centers Commercial: 234 commercial centers were identified using Google Maps, then categorized as: Mega Shopping, Shopping Center, Town Center, Galería, Mall, and Plaza
