The US Geological Survey (USGS) said the earthquake had a preliminary magnitude of 6.8, making it one of the strongest earthquake to ever hit the region around the lake.
Its epicentre was measured at a shallow depth of just six miles.
The area is not heavily populated but is home to a number of villages near the lake, including Hatgal and Turt, which have a combined population of up to 5,000 people.
There were no immediate reports of damage or casualties although experts said the tremors would have rocked the villages.
Earthquakes periodically occur in the regions of Mongolia bordering with the Russian regions of Tuva, the Altai Republic, the western part of Buryatia and China s Xinjiang region 96 miles).
An earthquake with a magnitude of 6.1 jolted 42 km WNW of San Antonio de los Cobres, Argentina at 0354 GMT on Sunday, the U.S. Geological Survey (USGS) said. The epicenter, with a depth of 202.77 km, was initially determined to be at 24.02.

(Reuters) - A warning for “hazardous tsunami waves” was issued briefly for coastal regions within 300 kms (186.41 miles) of Wau in Papua New Guinea’s northeast, after a 7.0 magnitude earthquake struck the region, the U.S. Pacific Tsunami Warning Center said.
The quake struck about 12.50pm local time at a depth of 85 km (52 miles), according to the U.S. Geological Survey (USGS), and struck offshore 18 kms (11 miles) east-southeast of Wau.
The Pacific Tsunami Warning Center initially issued a tsunami warning but said about an hour later the danger had passed.
There were no immediate reports of casualties or damage from the quake, which was initially recorded at 7.3 but later adjusted, and the PNG National Disaster Centre declined to comment until it had received a briefing.
Sea Urchin Mortality in the Hawaiian Islands
Sea Urchin in Coastal Waters of Hawaii Science Center Objects
Scientists from the U.S. Geological Survey (USGS), University of Hawaii, the State of Hawaii Division of Aquatic Resources, and The Nature Conservancy are investigating unusual mortality of collector urchins (
Tripneustes gratilla) that has been ongoing since February 2014. As grazers, urchins play a critical role in preventing overgrowth of algae on tropical coral reefs. Awareness of the linkage between urchins and coral health became apparent in the early 1980s when 80 percent of the Caribbean coral cover and the biodiversity it supported was lost following a 90-percent decline in the urchin population over the 3.5 million square kilometer area within about 12 months.
