A strong earthquake measuring 4.6 has hit Marlborough.



GeoNet is reporting it was located 5km south east of Seddon, south of Blenheim followed by a 3.3 located 30km east of Turangi.



The quakes hit shortly after 5.30pm.



Chris Sutherland was enjoying a pint in Paddy Barry's pub in Blenheim when he felt the jolts.



"I was sitting on a bar stool and it rocked a bit and the drinks on the table moved a little bit. Luckily my drink wasn't spilled. If it had I would have licked it off the table."



Pam Tawhara said it knocked over her cuppa and she had to hold onto her desk and computer.



"It took years off my life."



Jodi Cane from Seddon said it "felt like a train coming though our lounge, quite a shake."



Robyn Thomson said her car parked in Springlands in Blenheim rocked as a result of the jolts.



Wendy Gibson described it as a "rumbling jolt".



A St John spokesman said there were no reports of injuries or damage.



A Marlborough District Council spokeswoman said it was "no biggie" and there had been no reports of buildings damaged.
