Nam Bo met with a magnitude 5.5 earthquake

At 14:55 today, in Ho Chi Minh City, Vung Tau, Binh Thuan, Ninh Thuan . an earthquake occurred about 5 seconds. According to some people, this shaking was stronger than the vibration that occurred at 0.15 on the same day .

Unlike the earthquake at night, this time most of the areas in HCMC were shaken. Ms. Thanh Hang, an employee of FPT Company, Vo Van Tan Street, District 3, recounted, sitting in the room suddenly shook her desk. Computer like jumping out of place. Many office workers at nearby buildings all fall down the road. They were the ones who felt the most obvious shaking due to being on the high floor.

Bui Quoc Bao, the stage director, also told reporters, he was writing articles at his home on Cong Quynh Street, District 1, when he saw the land under his feet. He immediately ran to the street, where a lot of people were gathered and confused. A car driver also said that when he was traveling on Pasteur Street, District 1, he suddenly felt that the car seemed to be depressed . Many other places such as Tan Binh, Binh Tan, Phu Nhuan, District 9, District 2. . (HCMC) people also felt similar vibrations at the same time.

In Vung Tau City, Pham Thi Hanh, living in Tu Xuong Street, said that she felt that this shaking had the same intensity at 0.15 this morning. 30 minutes after an earthquake, many people in ward 4 still talk about it anxiously. Staff of Schlumberger Company (Oil and Gas Services), 65A of April 30 Street, Vung Tau City said, in addition to shaking sensations, some pieces of floor tiles in front of the office door were shoved together, cracked and cracked.

In Phan Thiet City, Binh Thuan Province, Ms. Nguyen Thi Hang said that, at around 15:00, while sitting at the Provincial Breeding Center, she felt a great shaking and spilled a table fan in the corner of the room. In the town of Phan Rang, Ninh Thuan province, some students are studying at the Center for continuing education when they put their hands on the table to see the shaking in seconds. Some other students are studying upstairs rushing to run down.

Similarly, Ms. Bui Kim Phuong at 78 Phan Dinh Phung Street, Ward 2, Da Lat City, Lam Dong Province, recounted about 15pm, she was in the house and felt a slight shaking phenomenon lasting 10 seconds. Particularly in Bao Loc town, quite strong tremors spilled a cupboard of a household.

The latest information from the Institute of Geophysics at 16h40, the results measured from the monitoring stations of Vietnam, the location of the earthquake at 1455 this afternoon is at the coordinates of 9.72 degrees North latitude, 108.22 East level with a magnitude of 5.5 richter . Thus, this is the second earthquake in the day, not just aftershock.

According to the Institute of Geophysics, the exact coordinates of the earthquake occurred at 0.15 am 9.96 degrees north latitude and 108.17 degrees east longitude, 5.1 richter intensity . Currently the depth of the earthquake of the earthquake in the day has not been determined.

Evaluation of the recent earthquake, Professor Le Minh Triet of the Vietnam Academy of Science and Technology said that some districts in Ho Chi Minh City such as Binh Chanh and Binh Tan . have suffered from tremors of level 6, Based on the phenomenon of falling chairs, knocking on the glass door when there is a vibration. Areas with only slight tremors are likely to have a shock of level 3, 4 or a maximum of 5. " This is the first time that southern provinces have been affected by the spillover of earthquakes with level 6 ", he said. Triet said.

The earthquake at 0h15 this morning in the Southern region was measured by the monitoring station of the Geophysical Institute of 5.1 magnitude. Head of Earthquake Monitoring Department 1 Institute of Geophysics Le Tu Son said that all earthquake observation stations in Vietnam and the world have been measured, but each station has reported different intensity. There is a measuring place of 4.9 degrees, but there is also a 4-richter notification station. Explaining this, Mr. Son said that due to the different ways of calculating the national observations, the results were different. After applying scientific countermeasures, the Earth Physics Institute officially announced that the magnitude of this earthquake was 5.1 richter.

At the beginning of this afternoon, according to information from world observation stations, the Institute of Geophysics concluded preliminary: earthquake coordinates at 10 degrees north latitude, 108 degrees east longitude, off the East Sea off the coast Vung Tau 100 km, located in the intersection of the Nam Con Son, Thuan Hai - Minh Hai - Ca Mau fault zones and 110 meridian fault off the East Sea .

This earthquake has a large impact on the South Central and Southeast provinces with the highest intensity in earthquakes that have occurred in the region so far. However, tsunamis are unlikely to occur in the South China Sea due to inappropriate seabed characteristics.

Professor Le Minh Triet, Chairman of the Interdisciplinary Scientific Council of Vietnam Academy of Science and Technology, affirmed that in the case of earthquakes in the South China Sea, tsunamis are unlikely to happen. " The condition for a tsunami to occur is that the magnitude of the earthquake above 6 magnitudes plus the sea floor must have a certain degree of fluctuation. While the strongest earthquakes measured in the region so far are 5.2 degrees. Richter, and the maximum estimate is only about 5.5 degrees so the tsunami in the South China Sea is unlikely, "Mr. Triet explained.

Compared to the earthquake that happened in August, according to many people, this time despite less aftershocks, the intensity is stronger. Mr. Tran Thanh Binh, a resident of Phan Dang Luu, Phu Nhuan District, said that his family is on the ground floor of the apartment but the feeling of aftershocks is very clear. "The ground shook like a heavy truck ran through, although my house was over 100 meters above the road ," said Binh. Panic also occurred in Ngo Tat To apartment households, Binh Thanh district because strong aftershocks also affected this area.

This is the third time of the year, earthquakes occurred in the southern provinces and the waves spread to HCMC, after two earthquakes in August and October 18.

Why has there been a continuous earthquake in this area in the past time, while many years ago this noun was quite strange to the Southern people? In response to this question, Professor Le Minh Triet said, it is likely that the southern fault zones are returning to the operation cycle.

" However, I am not affirming this because the earthquake studies in the south have only been short-lived and there are few data to confirm the process of each cycle ," Triet said. Director of the Institute of Geophysics Nguyen Ngoc Thuy also said that the first factor thought by scientists is due to the fault zone in the re-operation cycle. " But to confirm this, it is necessary to have scientific research projects while the current budget does not allow it, " Thuy said.

Looking back at the three earthquakes that have occurred in the past 4 months and the shockwaves affecting Ho Chi Minh City, Triet said that with the vibrations occurring, earthquakes are below level 5 (earthquake level Damage visible on the surface). " Level 5 will be more shocking, people in the house and both walking on the street or sleeping will feel it. The pets in the house are also recognizable and this level earthquake will collapse the unstable house. "Mr. Triet commented. Level 6 earthquakes cause major damage to the area such as trees falling, collapsing houses, cracking . However, Mr. Triet said: " Based on the earthquakes measured in the history of the land of the land Male, at the same time, on the map of Vietnam and world earthquake zoning, it is also difficult to find earthquakes on level 5 in the southern fault zones ".

Mr. Le Tu Son also emphasized the possibility of an earthquake chain in the southern fault zones and vibrations affecting the provinces in the region. " This is an earthquake phenomenon, the intensity is not great, but it occurs continuously for a period of months or a year. The earthquake is not worth worrying about because the energy has spread gradually so it is hard to have strong impacts. , compared to the "quake" earthquake, there is no sign of suddenly emerging as strongly as in Pakistan recently , "Mr. Son emphasized. Mr. Son also said that although Vietnam has not been able to predict earthquakes, it is estimated that there will be many other earthquakes with the same intensity as the last 3 earthquakes in the southern fault zones. .

What to do when an earthquake occurs?

If you are at home, in class or in a building: Sit down on the floor.Pull down on a large table or bed if it can withstand many falling objects, so when the house collapses there is still breathing air.If the table moves, follow the table;If there is no cover, find a wall to stop close to, use your arms to protect your head and neck.Avoid dangerous places like windows, underneath objects that hang on ceilings, mirrors or furniture of high height.Keep away from objects that may fall.If you are in the kitchen, stay away from refrigerators, stoves and cupboards.If the power goes out, use a flashlight.Do not use candles or matches because they can cause fires.Cover your face and head to avoid falling debris.Do not use elevators.If you hide under a sturdy furniture item, you should hold onto it and stay in a position ready to move with it.Hold in this position until the ground is completely shaken and feels safe to move.

If outdoors: Move immediately to a well-ventilated location, away from trees, signs, houses or below power lines and columns.Stay away from buildings and wires.Find a place to stand.If you are walking on the sidewalk near buildings, hide under the doorway to avoid falling tiles, glass, mortar and other debris.If you are driving (cars), stop by the curb and stop.Avoid overpasses, power lines and other dangerous things.Stay in the car until the concussion is over.

If you're in a crowded supermarket: Don't rush to the exit.Stay away from shelves that contain falling objects.

If you're in a stadium or theater: Sit in a chair, protect your head with your hands.Do not move until the concussion is over.If you see everything is okay, leave that orderly way.

Be prepared to deal with aftershocks and consciousness in the head where I will hide when there is aftershock.Aftershocks can occur after an earthquake a few hours, days, weeks or even months.
