Six new mud volcanoes have appeared along RE Road in Los Iros, South Trinidad and farmers are now calling for immediate relocation.
The area had been devastated by the 6.9 magnitude earthquake which rocked T&T and the Eastern Caribbean in August 2018.
During an interview with Guardian Media, farmer Amit Nagoo said a week ago they noticed bubbles coming up from the fissures left by the earthquake.
“Then we started to hear loud cracks and sounds of gas escaping. Then we started to see mudflows coming out at different points along the RE Road,” Nagoo said. He said since the earthquake they have been unable to cultivate several acreages.
“Now that the volcanoes are coming up, we cannot get access to the land. One volcano is at the centre of the road,” Nagoo said.
He said the area should be cordoned off and farmers relocated.
However, president of the Los Iros Hillview Farmers Association Rishi Ramraj said he was hoping that the Los Iros area could be developed as an agri-tourist site.
“We want this area to be developed. The volcano site is being used for fun activities and health. We already organize tours for school children who are interested in geology. We think it’s important to map the area and develop it as a tourist site,” Ramraj added.
He said its been almost two years since the earthquake but geologists and seismologists have been doing active research in the area.
Senior geoscientist from Touchstone Exploration Xavier Moonan, who broke the news of the volcanoes emergence told Guardian Media that the volcanoes appeared over the past week.
“The new cones all occur along the trace of the August 21st 2018 earthquake fault rupture which completely offset the roads along RE Trace.”
He revealed that oil sheen and the strong scent of hydrocarbons accompany the mudflow. Mud samples were collected for analysis and Moonan said the area will be closely monitored.
Teams from the University of the West Indies are expected to visit the area this week.
Moonan said despite the volcanoes farming should continue but the area must be monitored.
He said the main threat at the moment was that the volcanoes may block off or damage one of the roads in RE.
“There are other access roads for the farmers though,” Moonan explained.
He said after the earthquake, UWI Petroleum Geoscience took the initiative to conduct a seismic tomography (resistivity) study.
Aided with nearby oil well data from Touchstone Exploration, mapping of the rock layers was conducted. “The data showed that the surface rupture from the Aug 21st earthquake was indeed a reactivated older fault which runs deep into the subsurface. Faults are the key conduits for subsurface fluids (saltwater and hydrocarbons) to escape to the surface. When these fluids entrain clays they result in mud volcanoes at surface,” Moonan explained.
He said for the people in the area, the volcanoes could cause a bit of an inconvenience.
