Lebanon Dam Planned Atop Fault Line Stirs Fears

إقرأ هذا الخبر بالعربية W460

Lebanon's government says a dam planned for a valley near Beirut is vital to tackle chronic water shortages, but the location on a seismic fault line has raised fears among residents.

"How can you build a dam in an earthquake zone? We don't even have houses that are earthquake-proof," said Amer Meshmushi, a resident of Bisri Valley, 35 kilometers (20 miles) south of Beirut.

He grew up hearing about the last major earthquake on the Roum fault, in 1956, which killed 135 people and damaged thousands of houses including his family home in Basaba village.

"My brother was still little, and they had to drag him out from under the rubble," the 50-year-old recalled his parents telling him as a child.

Lebanon's government and the World Bank say the Bisri dam is desperately needed to address water shortages afflicting greater Beirut's 1.6 million residents. 

They insist the structure will be safe and say measures will be taken to mitigate seismic risks.

But Meshmushi's concerns are shared by local activists, including Raja Noujaim, head of the Association for the Protection of the Lebanese Heritage.

"When we look at the region's history and geography, we see that all of its valleys are the result of the fact that it is a seismic zone," he told AFP.

Activists say an earthquake could cause the dam to burst and that the structure and its reservoir would put pressure on the fault line and increase seismic activity.

- 'Wiping out farmers' -The World Bank and Lebanon's Council for Development and Reconstruction (CDR), a government agency that supervises major infrastructure projects, identified the valley as a prime location for a dam thanks to its abundant water, wide basin and proximity to Beirut.

In a report, the World Bank said a panel of four "internationally recognised experts" recruited by the CDR had reviewed safety studies, adding that the dam's design was "consistent with international best practice".

The World Bank told AFP that tests showed the dam had "a resistance to shocks above the one provoked by the 1956 earthquake," which measured a six on the Richter scale -- similar to the strength of the quakes that devastated central Italy last year.

Eli Mussali, the CDR engineer overseeing the project, said the dam could "withstand earthquakes up to eight on the Richter scale, which is a very high degree."

He also downplayed the possibility that the structure could provoke seismic activity, saying there was no evidence for such a phenomenon.

And he noted the country's largest dam, in the eastern region of Qaraoun, is situated atop the major Yammouneh fault line.

"It is geologically normal for faults to run between mountains, where rivers run and dams are built," he said.

At present, Lebanon stores just six percent of its water in reservoirs. Many people rely on illegally drilled wells that are increasingly over-exploited and produce water of dubious quality.

Construction of the Bisri dam is expected to begin later this year with a $617-million (544-million-euro) price tag, mostly covered by a World Bank loan.

It will take nine years to finish and will be the country's second-largest dam, with a capacity of 125 million cubic metres (4.4 billion cubic feet) in a reservoir covering 450 hectares (1,100 acres).

Land belonging to 15 villages will be gobbled up by the facility, including Meshmushi's fields.

"Does it serve Beirut's interests to wipe out farmers?" he asked. 

"These lands are the source of our livelihoods. They allowed me and my brother to get an education."

- 'Where will we go?' -Bisri Valley is covered in a patchwork of farms growing everything from lemons and pine trees to strawberries and pomegranates, mostly tended by seasonally hired Lebanese labourers and Syrian refugees. 

The CDR plan includes a fund to compensate owners of the 869 plots of land that will be expropriated, but it remains unclear if the farmers will also be compensated for losing their jobs.

Fifty-year-old Abu Salem has farmed beans in the village of Marj Bisri for 25 years.

"I'm a farmer, not a civil servant. I don't have anywhere else to go," he said, sitting on a tractor.

"I taught my children how to farm. If we leave here, where will we go?"

Locals also fear for archeological sites that will disappear under the water. 

They include the Mar Musa church in Marj Bisri, a tiny stone edifice locals say is hundreds of years old and has become a shrine for residents of all faiths.

Authorities proposed to dismantle the church and rebuild it elsewhere, but villagers rejected the offer. 

Further downstream are five columns, four standing and one toppled, that are believed to be Roman and could be evidence of a larger archaeological site.

That area will one day be at the bottom of the reservoir.

The CDR's Mussali said there are plans for the Antiquities Department to excavate the site and decide if it is worth saving.

But residents say the dam project should be scrapped entirely.

"We shouldn't be thinking about building anything in the area, whether a dam or anything else," said Noujaim. "It's dangerous. This project mustn't be done."

Theres always bound to be protests against project like these, especially from local residents. This happens all over the world. But at the end of the day one have to look at what benefits the country as a whole. If this project is given the clear from international experts, at least we can forget about theories like conspiracy and bribery. The people who have their land and livelyhood there should of course be compensated. In the case of farmers also for future income.

1) Concern for a potential earthquake should be shifted to being concerned about the homes all over Lebanon to be able to withstand such an event since earthquakes will happen regardless of the presence of the dam or no
2) Regarding lands, people should be compensated with an equally or more valuable land with regards to how the current land is being used taking into account terraces, arability...
3) Regarding archaeology a magnetic study coupled with a couple of excavations in key points of interest (costing no more than 20,000$) is more than enough to determine the importance of the site
4) The church can be moved...
In the end, I doubt that the people would be complaining once they have a lake which has plenty of potential for resorts and restaurants

The main concern when it comes to the earthquake is if the dam would rupture in the event of an earthquake which would be easily solved by properly constructing the dam.
With regard to increasing the frequency of earthquakes then that won't be much of an issue since only this fault (which is a minor fault and could cause max 6.0) would be effected by the dam (Lebanon has thousands of faults everywhere). The real danger is from the main faults which could cause earthquakes up to 8.0 which is the Yamouneh fault and the mount Lebanon thrust fault but no one seems to care enough to take action to be prepared when that happens.
In any case wherever you go to build a dam it will be on a fault...... rivers follow fault lines since they provide the easiest route to the low lands...

I'm more concerned about the fact that it will be built on LOAN from the World Bank...........

Fortunately I am a geophysicist... In simple terms, reservoirs and dams aren't causing earthquakes they are causing the water content of the rocks under them to increase which means the faults would become "lubricated" and would move earlier than they would if the dam and reservoir aren't present...

There is a fault in the area so earthquakes will happen every XXX years on that fault. The presence of the dam would cause that time to change to around every xxx-yyy years.

And yeah!!! Exploration diving would be awesome!
