THIS is the nerve-wracking moment doctors continue performing cancer surgery on a patient during the monster Russian 8.8 magnitude earthquake.

The massive quake hit off Russia’s far eastern Kamchatka peninsula on Wednesday, the US Geological Survey said, wreaking chaos across the Pacific.

The quake struck about 84 miles out at sea at around 7.24pm EST (12:30am BST) at a shallow depth of 19.3km (12 miles).

It is the largest since the 2011 monster which led to a tsunami that caused the Fukushima nuclear disaster.

Now unbelievable footage has emerged of doctors managing to continue performing surgery while the horror quake unfolded.

The brave doctors in Russia are captured looking at one another as the apparatus around them begins to shake.

One is seen desperately holding onto instruments before one falls to the floor.

The other surgeons managed keep their hands still over the patient as the quake rocks their bodies.

They all appear to look around in desperation for any help while all the room continues to tremble.

The doctors then appear to bravely continue the cancer operation despite the chaos.

While the patient is under anesthesia, a surgeon carefully raises the sheet that covers their face, likely to ensure that nothing is out of the ordinary.

In response to what ranks as the sixth largest earthquake recorded, tsunami warnings have extended to South America, following the evacuation of almost 2 million people from Japan’s coastal areas.

Huge aftershocks continue to hit the area and resulting tsunamis could last for more than a day.

Waves have already hit Russia, Japan, Hawaii, and California.

A 4m (13ft) high wave was recorded on the southern tip of Kamchatka with waves inundating low lying areas and thousands evacuating.

Hawaii has seen waves nearly 6ft high, but officials believe the worst might be over and have downgraded warnings.

A family from Britain, currently on vacation on the island, shared with The Sun their experience as they find themselves stuck on the 16th floor of their hotel amidst the arrival of the initial tsunami waves.

Some 1.9m people in Japan have been ordered to evacuate with a 1.3m (4ft) wave hitting the country.

It’s a nightmare scenario for the country that suffered a nuclear disaster at Fukushima in 2011 caused by a tsunami.

Workers from the nuclear plant have been evacuated and are monitoring it remotely.

Tsunami warnings are in place for as far away as Colombia, Peru, and Ecuador.

Waves have also hit the mainland US, including California, Oregon, and Washington.

President Donald Trump addressed the incident after the earthquake, stating: “Due to a significant earthquake in the Pacific Ocean, a Tsunami Warning has been issued for residents in Hawaii.

“Additionally, a Tsunami Watch is active for Alaska and the Pacific coastline of the United States. Japan is also at risk. Please check tsunami.gov for the latest updates. STAY STRONG AND STAY SAFE!”
