Earthquake assessments conducted in South Rupununi
Home Affairs Minister Robeson Benn has dispelled the fears of residents in the South Rupununi, Region Nine (Upper Takutu-Upper Essequibo), who were considering abandoning their villages in the wake of the January 31 earthquake, which was most pronounced in that area of Guyana.
Benn, a geologist by profession, visited the villages of Katoonarib and Sawariwau, Deep South Rupununi, where there were structural damage and cracks in the earth’s surface.
He was accompanied by fellow geologist Leandro Pires; Director General of the Civil Defence Commission, Lieutenant Colonel Kester Craig, and a CDC team on the weekend visit.
The technical team conducted inspections to gather information to prepare for any recurrence.
During a community meeting in Katoonarib on Saturday, Minister Benn noted that earthquakes in that area were rare and persons should not migrate.
“This is not necessary, and it will only cause enormous distress, dislocation and unnecessary expenditure of money. There is no need to leave your homesteads to go to any other place.”
Benn also rebuffed rumours that the earth’s plate’s shift was caused by the oil extraction activities in Guyana’s maritime space.
“That is completely impossible. If that were the case, we would have lost the seawalls, the city of Georgetown and everything would have been in the ocean already. Not to happen all the way out here, some 700 miles in the Rupununi. It is totally unrelated, and I want to dispel those suggestions that it is related to oil extraction out on the coast or in the ocean. We have taken out much more volumes of pure water for drinking than we have for oil for those sediments going out there. So, those things are totally untenable in relation to these events.”
The Home Affairs Minister noted that a geological technical report on the earthquake’s effects would be completed and shared with the Government and the affected communities.
Meanwhile, Head Teacher of Sawariwau Primary, Lennox Henry complained that vibrations and loud rumblings were being felt and heard continuously. He added that they felt a movement of the earth as recently as Sunday morning.
Pires noted that the rumbling sounds are normal following an earthquake and should not be a cause for concern. He added that a release of energy causes the noise through the cracks in the earth.
“It supposed to happen for another couple of weeks, and then after that, it should finish. It is a very rare event for an earthquake to happen inside a stable plate like where the whole of South America is located, except for the Andes Mountains,” the geologist said.
Benn also assured the residents that there would be seismic and audio monitoring and gravity and monoatomic assessments of the area.
Meanwhile, CDC Head Lt Col Craig reported that there was minor damage as a result of the quake. Two houses in Katoonarib suffered some damage, while there were several cracks in houses and Government facilities in Sawariwau.
Of concern to the CDC is the type of materials used to construct buildings in the Rupununi. The buildings mainly have thatched roofs made from ité palm and walls made from adobe bricks, which cannot withstand an earthquake’s shocks.
“They are good under normal circumstances but thinking about seismic actions like what has occurred, some emphasis may have to be looked at how can we improve the construction and the building codes for these areas. So, we are going to have some discussions with Public Infrastructure to come and do some structural assessments to come up with recommendations of improvements in terms of construction,” Lt Col Craig said.
One resident of Katoonarib whose wall collapsed, Grace Cyril, relayed that the incident occurred while she was out of the area. She expressed appreciation for the assistance provided by the Regional Democratic Council to repair her home.
During an inspection in Katoonarib, the team observed visible cracks in the earth and three areas of sizable depressions.
Over the next three days, a small team from the CDC will conduct continuous assessments in the affected communities.
Meanwhile, Deputy Toshao of Katoonarib, Florie Singh is satisfied with the Government and the CDC’s intervention.
The shift of the earth’s plate occurred about 10km below the surface.
