High-rise building residents in some areas in Hanoi experienced again light tremors at 6:49am on November 28, local media reported.

The shakes possibly resulted from a 4.7-magnitude earthquake hitting Trung Khanh district in Vietnam’s northern province of Cao Bang, which is about 300 km away from the capital city.

Nguyen Minh Hung, living on the 12th floor of an apartment building on Minh Khai street, said that he saw furniture at his home shake slightly.

"I guessed that it was most likely due to the impact of earthquakes somewhere," Hung said.

The tremor shook furniture, windows, cups and glasses on the tables inside houses and buildings.

According to the Institute of Geophysics, the earthquake occurred at the position of 22.844 degrees north latitude, 106.581 degrees east longitude and at a depth of about 10 kilometers. This has been the third earthquake in Cao Bang in the past four days, after two of 5.4 and 3.8 magnitude on November 25.

Earlier, on November 21 and 25, the capital city of Hanoi experienced tremors which unsettled the residents. The Institute of Geophysics determined that the tremors resulted from a 6.1-magnitude earthquake hitting Laos’ northwestern province of Sayaboury and another one striking Cao Bang.

Three consecutive earthquakes in the past few days in Cao Bang have disquieted the people.

However, Zing.vn quoted Dr. Cao Dinh Trieu, former Vice President of the Institute of Geophysics as saying that the phenomenon is nothing unusual.

Trieu explained that the biggest earthquake on November 25 (5.4 magnitude) followed by weakening seismic activities of smaller magnitude is the rule of this natural phenomenon.

Hanoi is not an earthquake prone area, but sometimes suffers from aftershocks shaking the city, Trieu added.
