The Shaer gas field – one of the biggest in the central province of Homs – has been the site of fierce fighting between ISIS terrorists and Syrian government loyalists.
A monitoring group said ISIS reportedly blew up several of Shaer's pumping stations just as the European-Mediterranean Seismological Centre recorded a 4.4-magnitude earthquake in the area.
'There were three huge explosions there carried out by ISIS on Monday,' said Rami Abdel Rahman of the Syrian Observatory for Human Rights. He had no immediate word on casualties.
The explosions reportedly even shook Palmyra, the ancient oasis city about 30 miles southeast of Shaer, according to reports posted on Twitter.
Syria's army recaptured Palmyra from ISIS on March 27 after about 10 months of terrorist rule over the city.
ISIS seized the Shaer field last week, but Syrian armed forces and pro-government militias have fought hard to get it back.
ISIS has targeted oil and gas facilities in Iraq and Syria to fund its self-proclaimed extrimis 'caliphate'.
More than 270,000 people have been killed since Syria's conflict erupted in March 2011 with protests against President Bashar al-Assad.
It comes as an expert warned that ISIS had an 'almost limitless' supply of chemical weapons such as mustard and chlorine gas.
Hamish de Bretton-Gordon, who has recently returned from training Kurdish fighters how to use gas masks, said he had witnessed the effects of chlorine attacks first hand, Daily Mail reported.
