False earthquake warning due to positioning software

Acknowledging that the warning about the August 25 earthquake in Phu Yen was flawed, the head of the Tsunami Earthquake Reporting Center said that part of the software was wrongly located and also There are also elements of human impact.

>>>Earthquake 300 km from Phu Yen coast
>>> The earthquake reaches 6.8 on the Richter scale off Vietnam

Although not taking account of any responsibility, many scientists in the industry said that these errors must be frankly acknowledged by many larger, more important problems from these small associations.

One glass, easy one mile . !?

Assoc.Prof.Dr. Nguyen Hong Phuong, Deputy Director of the Tsunami Earthquake Reporting Center, the Institute of Geophysics, bluntly acknowledges that giving false warning messages is due to the inaccuracies of equipment.

According to Assoc. Phuong, with an individual, the duty officer (at 1pm) complied with all warning regulations. They may have errors in terms of parameters and positions, but soon corrections are made.'A process is not immediately all devices are detected correctly and it must be reported continuously until the danger is over , ' said Phuong.

Mr. Phuong further demonstrated in the tsunami warning, one must continuously broadcast the notice, if the tsunami still continues to cause danger, it must continue processing all data, repositioning all both earthquakes to determine the possibility of the tsunami being raised or diminished until the final order is issued, then the reporting process will be terminated.

'In this case, the operator has checked the information on the international networks found to be wrong due to navigation software, so he adjusted and had a timely notice. 'Sometimes it is due to the overloaded working capacity of the machine so it should not be taken. Saying the wrong news to lose faith is to raise the opinion , 'Associate Professor Phuong said.

The release of an incorrect newsletter, Associate Phuong said, any country in the world can happen this situation, such as the earthquake in Sendai (Japan) in March 2011, The US Geological Survey initially reported an earthquake magnitude of 7.9 on the Richter scale but then corrected it to 8.8 and 8.9 on the Richter scale.

Need to ensure accurate information

At the Ninth National Nuclear Technology Conference, which has just been held in Ninh Thuan, there are many opinions of geologists that it is necessary to clarify the geology at the site to be constructed. 2 first nuclear power plants of Vietnam.

Therefore, the above-mentioned error has not occurred yet, but according to some experts, this is a straightforward story to draw experience.

A scientist who asked for anonymity refused to give an opinion on the matter, but from a technical perspective, he thought that in this case, it was necessary to check all the geological waves coming from the stations. New analysis.

Here, input information is very important, so it is the people who understand the problem, the human factor is very important, if the input is wrong, it will be totally wrong. This scientist also warned, this is only a small example for calculations related to fault zones, problems related to geology .

Do not give any personal opinion or comment about the incident, but Associate Prof. Dr. Cao Dinh Trieu, Vietnam Geophysical and Technical Association is really worried. He thinks that professionals need to consider everything to ensure the most accurate information. With the release of an earthquake warning message based on the automatic calculation program, but because the operator put the parameters into the calculation, the results were not accurate.
