Days after a 6.4-magnitude earthquake rocked Puerto Rico, followed by hundreds of aftershocks, the full extent of damage is only beginning to be realized.
NASA scientists are using satellite data to help federal and local agencies identify areas with potential damage. Earthquakes cause permanent changes to the ground surface. By comparing interferometric synthetic aperture radar (InSAR) data acquired on Jan. 9, 2020, with data acquired on Dec. 28, 2019, from the Copernicus Sentinel-1A satellite, the scientists were able to map where, how much and in what direction those changes occurred.
Managed by the European Space Agency (ESA), the Copernicus Sentinel-1A satellite was able to see the eastern two-thirds of the island during the Jan. 9 flyover. On the map, red indicates areas where the ground was changed, or displaced, with darker shades corresponding to more significant displacement. The scientists found that the greatest displacement from the flyover area occurred west of the city of Ponce (identified by the green star), not far from the quake's offshore epicenter. They recorded up to 5.5 inches (14 centimeters) of ground change there. The ground appeared to shift downward and slightly to the west.
The quake epicenter and the cluster of quakes and aftershocks in the region identified by the United States Geological Survey (shown as orange circles) fall just west of the satellite's Jan. 9 track. Because of this, scientists also plan to analyze data from Sentinel-1A's forthcoming Jan. 14 flyover, which will include western Puerto Rico.
The NASA Earth Applied Sciences Disasters Program has activated Tier 1 response in support of this disaster and is in contact with the Federal Emergency Management Agency, the United States Geological Survey and Health and Human Services (HHS) to provide NASA Earth-observing data in support of response and recovery efforts. Products in the process of being produced include Suomi-NPP-based “Black Marble” power outage maps, damage maps, and landslide maps. A webpage has also been created on the NASA Disasters Mapping Portal to supply relevant GIS data products.
The map contains modified Copernicus Sentinel data processed by ESA and analyzed by scientists at NASA's Jet Propulsion Laboratory, and earthquake location data from the USGS.
The rings around your anus are visible from space. I mean, heads or tails on that dime laying there........
Earth Visible From Space, JPL Scientists Astounded!
Are they wanting the mainland to send them more food and water to rot in the sun?
Hurricane Maria demonstrated the weakness of Puerto Rico’s electrical infrastructure.
The earthquakes are showing the weakness of Puerto Rico’s water and sewer infrastructure.
But Puerto Rico has been run by communist Democrats for decades, so it should resemble Detroit, San Francisco, Chicago and St Louis.
I grant the damage and injuries suffered by the Puerto Rico’s people.
But this press release by JPL is just another federal agency publicizing a “look at what I can do!” The information does little but confirm where the epicenter was, where it moved to. And the people doing repairs on the ground knew that already.
Apparently, you’ve never watched “What on Earth?” on the SCI channel. .....The satellites uncover many obscure things in forests, deserts, etc. Then, people go to those sites to investigate what they are and their history.
They had an 8 inch tsunami. I’m not kidding. In their case I don’t think 8 inches made a difference.
These days, cigarette labels are visible from space....
“They recorded up to 5.5 inches (14 centimeters) of ground change there. The ground appeared to shift downward and slightly to the west.”
Uh oh. More evidence of rising sea levels.
Guam and Saipan had a 7.7 Earthquake 3 years ago. If I understand the scale correct this is exponentially bigger than the one on Puerto Rico. A 6.4 would be considered an excuse (as if any were needed) to BBQ.
They are poorer than Puerto Rico with less money for redevelopment. You never heard about it because they enforce building codes better. Nobody died and the Internet didn’t even go down.

That Saipan quake was ‘deep’ at over 233km (145 miles) and not all that close to the island. Shallow quakes cause greater damage.
What? and no one’s blaming Trump? Yet.
Stupid statement. They can read individual license plates from space why not earthquake damage.
every Puerto Rican that I have met in the US votes democrat—probably because they were used to getting everything for free in PR.
“”What? and no one’s blaming Trump? Yet.””
AND must be AOC is taking a long winter nap because I haven’t heard her blaming the president for not reacting fast enough to help her auntie or her cousins or whoever! Maybe she’d like to volunteer to go down and help out????
looks like they had another 5.9 this am. that’s gotta hurt on already weakened structures
The Clinton’s avarice is visible from space.
