The state of Oklahoma, which witnessed US President Donald Trump return to the presidential campaign trail on Saturday after the coronavirus pandemic swept the country, registered an underground tremor in parts of Tulsa late on 20 June, with the United States geological society saying the epicentre of the 4.2 magnitude earthquake was northwest of Perry, Oklahoma.
The US Geological Survey said the quake took place at a depth of 7.9 km.
While there were no reports of damage, people took to Twitter and Facebook, not only posting about feeling the quake in different parts of Tulsa, but musing over the coincidence of an Oklahoma earthquake on the night of a Trump rally.
On the eve of the Oklahoma campaign rally, Donald Trump had promised his supporters a "wild evening", and insisted that it was time "to get back to living our lives".
Trump's rally had originally been planned for Juneteenth, a day that commemorates the freeing of black slaves in the US, but was postponed one day after widespread criticism.
