A total of 9,960 landslides were triggered in Dominica during the passage of Hurricane Maria in September 2017, a large-scale landslide inventory/study carried out by the University of Twente has revealed.
The inventory was done with the use of five scenes of Pléiades satellite imageries which were obtained on September 23 and October 5 after the hurricane, made available through UNITAR-UNOSAT.
A series of images from Digital Globe Images were also used that were collected for the Google Crisis Response.
The images were visually interpreted by image interpretation experts, and landslides were mapped as polygons, separating scarp, transport and accumulation areas, and classifying the landslides in types.
According to the inventory of 9,960 landslides identified, 8,576 were debris slides, while 1,010 were debris flows and 374 were rock falls.
It said Almost all of the rivers flooded due to intensive precipitation.
The study warns that the island will be facing more problems with landslides in the coming years.
“Dominica will face some new problems for mountain hazards in the coming years, as many of the fresh scarps may produce more debris, and many tree trunks are still on the slopes or in the river channels,” it said.”With so many fresh landslides in the upper catchments, it is likely that debris flows will be triggered with rainfall thresholds that are substantially lower than before the hurricane.”
It also said that the hurricane has damaged Dominica’s rainforest dramatically and this could result in more landslides and flooding.
“Without the protection of vegetation, more new shallow landslides could happen in the near future,” the study said. “A series of cascading hazards may happen, for example, landslides or debris flow blocking rivers and resulting in outburst floods. Therefore more detailed evaluation of the post-Maria hazard and risk situation is very important.”

The University of Twente is a public research university located in Enschede, Netherlands.
When it comes to talking rubbish nothing could compare with Dominicans especially those of workers calamity party, leaders such as Linton, and his sidekicks most of all some workers supporters 90% of that lots, in the UK the white man would say fools always follow screw heads idiots. AND that’s true to the facts.
How does that comment add value to the subject matter?
Great map. Thank-you University of Twente! Multiple Maria landslides along single watersheds will probably result in massive mudflows (lahars) such as just occurred recently at Mont Pelee in Martinique. As mentioned in this research, the big question is vegetation – how much will die? As most farmers know, once the root systems on slopes are rotted the land will be washed away.
We may end up like Haiti. Too much slash and burn farming washing the soil away. Best we leave the land fallow for the time being and ban hillside farming on steep slopes altogether.
Allu cannot see is curse land that their? 10,000 land slides?! We have more lands in one night than people living in Dominica, don’t let me get started on the amount of traffic accidents and flooding DA have, DA never win no sports, or big singing competition smh
There. Not Their. And we have more than 10,000 people living here. And we do win in sports occasionally
Keep lying to yaself
Dominican passport, I know your identity i also know that you are a loser, hiding overseas just be careful you don’t fall on your sword ok!!!!
Man bite dog, are you okay? Not cat man suppose to bite? You out here lookin for dogs, leave me be
Also 10000 schools, it’s not too latte to attend one… you should be able to think and write if you do.
Maria saw the church could no longer say it is wrong to receive bribe because they took bribe to put church roof, church air condition and even to pay church rent. Maria saw that because of the Red Clinic, we could no longer preach from Thessalonian 3:10 that reads: For even when we were with you; during our residence in Thessalonica. “This we commanded, that if any man would not work, neither should he eat.” We could not preach against fornication; we could not preach against adultery; we could not preach against witchcraft or against anything because we compromised our faith. Imagine we could not even say Jesus is LORD! why? because we said at Portersville our king is ‘jesus’ and that we could not defend. The only thing we could preach on is “becoming a “millionaire”, like our king even if we have to sell our soul to the devil like our king sold our passports to evil people. Maria saw Dominica was in serious trouble and had to come to our rescue with almost 1000 landlides
It would have been nice if they had this befor Maria. There may have been landslides that happen before maria counted. Trees were stripped away on September 18th so old landslide features may have looked like new and i am not sure if the can differentiate the ones before maria and after maria unless additionl ground work is done. Anyway this is good information so gov can act upon. I would suggest starting a lumber facility maling pressed wood material. There may be valuable hard wood in the forrest right now. Get a couple helicopters and lumberjacks emploed fulltime. That can be a productive use of the CBI funds.
They used drones to verify many. Much of the wood is to steep and inaccessible even by choppers, unlike Oregon where they get close up to harvest and create bald mountains without any requirement to replant.
I just took a closer look at the map and I am not seeing any landslides between Warner and the Sultan Junction. I know for sure there were at least five (5) Landslides on that section of road.
Seems like Maria was very upset with Dominica and wanted to send a very strong message. The question is, did we get it? In like manner, it would also be very nice if the same university or another one, could conduct a survey to see how many churches were damaged by Maria. I say so because we all know that the church with some of our most respected bishops, evangelists, pastors, and priests played a very significant role in allowing and supporting Skerrit turn Dominica into one of the most corrupt countries in the face of the earth, and they said nothing. So helpful they were that they renounced some of their most fundamental teachings wrong, just to ensure that Skerrit was seen as right. How could Maria not be upset with us and punish us like we have never seen before in our history? Imagine churches took bribe to cover church roof and put air condition? Did they survive? If that’s not bad enough imagine a popular evangelist delivering bribe like fedex! Maria says EVIL is WRONG!!
I am convinced that if the Church had not compromised God’s word in an effort to cover the daylight evils of their king, Maria saw too much evil that became right! We heard of alleged sexual misconduct against minors all over Dominica like we never heard before; But the church was silent. The church could not even preach, teach or read Pro. 14:34 “Righteousness exalteth a nation: but sin is a reproach to any people” because they were careful not expose their lord. Imagine they could not even preach about “the Spirit of Ananias and Sapphira” of Acts 5, because it speaks of ACCOUNTABILITY and TRUTHFULNESS that their king is weak in. You remember how they strongly they used to preach against Lodge and illuminati? But all of a sudden it became right to the point that their king got knighted right here, in broad day light and they said nothing! They could not like John The Baptist say, it is wrong to marry somebody’s spose as long as they are alive. In fact they went to the wedding
