New look at Puerto Rico post-Hurricane Maria

December 10, 2018

When Hurricane Maria struck Puerto Rico head-on as a Category 4 storm with winds up to 155 miles per hour in September 2017, it damaged homes, flooded towns, devastated the island’s forests and caused the longest electricity black-out in U.S. history.

Two new NASA research efforts delve into Hurricane Maria‘s far-reaching effects on the island’s forests as seen in aerial surveys and on its residents’ energy and electricity access as seen in data from space. The findings, presented Monday at the American Geophysical Union meeting in Washington, illustrate the staggering scope of Hurricane Maria’s damage to both the natural environment and communities.

An Island Gone Dark

At night, Earth is lit up in bright strings of roads dotted with pearl-like cities and towns as human-made artificial light takes center stage. During Hurricane Maria, Puerto Rico’s lights went out.

In the days, weeks and months that followed, research physical scientist Miguel Román at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and his colleagues developed neighborhood-scale maps of lighting in communities across Puerto Rico. To do this, they combined daily satellite data of Earth at night from the NASA/NOAA Suomi National Polar-orbiting Partnership satellite with USGS/NASA Landsat data and OpenStreetMap data. They monitored where and when the electricity grid was restored, and analyzed the demographics and physical attributes of neighborhoods longest affected by the power outages.

A disproportionate share of long-duration power failures occurred in rural communities. The study found that 41 percent of Puerto Rico’s rural municipalities experienced prolonged periods of outage, compared to 29 percent of urban areas. When combined, power failures across Puerto Rico’s rural communities accounted for 61 percent of the estimated cost of 3.9 billion customer-interruption hours, six months after Hurricane Maria. These regions are primarily rural in the mountainous interior of the island where residents were without power for over 120 days. However, even more heavily populated areas had variable recovery rates between neighborhoods, with suburbs often lagging behind urban centers.

The difference between urban and rural recovery rates is in part because of the centralized set-up of Puerto Rico’s energy grid that directs all power to prioritized locations rather than based on proximity to the nearest power plant, Román said. Areas were prioritized, in part, based on their population densities, which is a disadvantage to rural areas. Within cities, detached houses and low-density suburban areas were also without power longer.

“It’s not just the electricity being lost,” Román said. “Storm damage to roads, high-voltage power lines and bridges resulted in cascading failures across multiple sectors, making many areas inaccessible to recovery efforts. So people lost access to other basic services like running water, sanitation, and food for extended time periods.”

The absence of electricity as seen in the night lights data offers a new way to visualize storm impacts to vulnerable communities across the entirety of Puerto Rico on a daily basis. It’s an indicator visible from space that critical infrastructure, beyond power, may be damaged as well, including access to fuel and other necessary supplies. The local communities with long-duration power outages also correspond to areas that reported lack of access to medical resources.

The next step for Román when looking at future disasters is to go beyond night lights data and sync it up with updated information on local infrastructure — roads, bridges, internet connectivity, clean water sources — so that when the lights are out, disaster responders can cross-reference energy data with other infrastructure bottlenecks that needs to be solved first, which would help identify at-risk communities and allocate resources.

The Buzz-Cut Forest

Hurricane Maria’s lashing rain and winds also transformed Puerto Rico’s lush tropical rainforest landscape. Research scientist Doug Morton of Goddard was part of the team of NASA researchers who had surveyed Puerto Rico’s forests six months before the storm. The team used Goddard’s Lidar, Hyperspectral, and Thermal (G-LiHT) Airborne Imager, a system designed to study the structure and species composition of forests. Shooting 600,000 laser pulses per second, G-LiHT produces a 3D view of the forest structure in high resolution, showing individual trees in high detail from the ground to treetop. In April 2018, post-Maria, the team went back and surveyed the same tracks as in 2017.

Comparing the before and after data, the team found that 40 to 60 percent of the tall trees that formed the canopy of the forest were damaged, either snapped in half, uprooted by strong winds or lost large branches.

“Maria gave the island’s forests a haircut,” said Morton. “The island lost so many large trees that the overall height of forests was shortened by one-third. We basically saw 60 years’ worth of what we would otherwise consider natural treefall disturbances happen in one day.”

The extensive damage to Puerto Rico’s forests had far-reaching effects, Morton said. Fallen trees that no longer stabilize soil on slopes with their roots as well as downed branches can contribute to landslides and debris flows, increased erosion, and poor water quality in streams and rivers where sediments build up.

In addition, the lidar surveys across the island corroborate findings presented at AGU by ecologist Maria Uriarte at Columbia University in New York City, who looked at tree death and damage rates in ground plots at the National Science Foundation Luquillo Long-Term Ecological Research site. Uriarte found certain tree species were more susceptible to the high wind damage, while others such as the palms, survived at higher rates, along with shrubs and shorter trees in the understory.

Morton and Uriarte will continue to follow the fate of Puerto Rican forests as they recover from hurricane damages using laser technology from the ground to make detailed measurements of forest regrowth.

Researchers at the University of New Hampshire have found unprecedentedly high levels of nitrate, an essential plant nutrient, in streams and watersheds of Puerto Rico for a year after two consecutive major hurricanes in 2017. This high amount of nitrate may have important climate change implications that could harm forest recovery and threaten ecosystems along Puerto Rico’s coastline by escalating algal blooms and dead zones: here.

Trump bans helping devastated Puerto Rico

Trump Is Now DENYING That 3,000 Puerto Ricans Died In Hurricane Maria

Just when you thought Donald Trump couldn’t sink any lower with his denial of reality, he comes along and Tweets that nearly 3,000 American citizens DIDN’T die during Hurricane Maria in Puerto Rico, and that somehow this death toll number is the fault of the Democrats. This is reality-denial the likes of which we’ve never seen from the Oval Office, as Ring of Fire’s Farron Cousins explains.

Trump wants no more relief funds for Puerto Rico

President Trump doesn’t want to give Puerto Rico any more federal money for its recovery from Hurricane Maria, White House officials have told congressional appropriators and leadership. This is because he claims, without evidence, that the island’s government is using federal disaster relief money to pay off debt.

The big picture: Trump also told senior officials last month that he would like to claw back some of the federal money Congress has already set aside for Puerto Rico’s disaster recovery, claiming mismanagement.

The White House didn’t comment on this reporting.

  • Between the lines: Trump won’t be able to take away disaster funds that have already been set aside by Congress, and sources close to the situation tell me the White House hasn’t asked Republican lawmakers to do so. But Trump could refuse to sign a future spending bill that would make more money available for Puerto Rico‘s recovery.

Behind the scenes: In late October, Trump grew furious after reading a Wall Street Journal article by Matt Wirz, according to five sources familiar with the president’s reaction. The article said that “Puerto Rico bond prices soared … after the federal oversight board that runs the U.S. territory’s finances released a revised fiscal plan that raises expectations for disaster funding and economic growth.”

  • Sources with direct knowledge told me Trump concluded — without evidence — that Puerto Rico’s government was scamming federal disaster funds to pay down its debt.
  • On Oct. 23, Trump falsely claimed in a tweet that Puerto Rico’s “inept politicians are trying to use the massive and ridiculously high amounts of hurricane/disaster funding to pay off other obligations.”
  • At the same time, White House officials told congressional leadership that Trump was inflamed by the Wall Street Journal article and “doesn’t want to include additional Puerto Rico funding in further spending bills”, according to a congressional leadership aide. “He was unhappy with what he believed was mismanagement of money”, the aide said.
  • A second source said Trump misinterpreted the Journal article, concluding falsely that the Puerto Rican government was using disaster relief funds to pay down debt.
  • A third source said Trump told top officials in an October meeting that he wanted to claw back congressional funds that had previously been set aside for Puerto Rico’s recovery. “He’s always been pissed off by Puerto Rico“, the source added.

Trump’s wariness about sending federal money to Puerto Rico dates back to the beginning of his administration. In early 2017, when negotiating the omnibus spending bill, Democratic congressional leaders were pushing Trump to bail out Puerto Rico’s underfunded health care system that serves the island’s poorest citizens.

  • Trump insisted in the negotiations that he wouldn’t approve anything close to the level of funds Nancy Pelosi and other Democrats requested, according to two sources involved. (And he didn’t.)

The bottom line: Congress took steps to keep disaster relief funds from being used to pay down the island’s debt, and as Bloomberg reported at the time, “neither the island’s leaders — nor the board installed by the U.S. to oversee its budget — are proposing using disaster recovery aid to directly pay off bondholders or other lenders.”

Why it matters: Congress will have to pass a new package of spending bills in December. Hill sources say the package may include a bill to send more federal money to disaster areas. Trump has told aides he believes too much federal money has already gone to Puerto Rico — more than $6 billion for Hurricane Maria so far, according to FEMA. (The government projects more than $55 billion from FEMA’s disaster relief fund will ultimately be spent on Maria’s recovery.)

  • In comparison, per the NYT, “when Hurricane Katrina hit the Gulf Coast in 2005, Congress approved $10 billion for the Federal Emergency Management Agency four days later, and another $50 billion six days later. The federal government is still spending money on Katrina assistance, more than 12 years after the storm’s landfall.”

Trump often blames Democratic-controlled states for the fallout from their natural disasters. On Saturday, Trump threatened “no more Fed payments” for California to deal with its deadly fires unless the state addresses what Trump claims is “gross mismanagement of the forests.”
