Is the earthquake in Lai Chau worrying?

One or two days apart, Lai Chau happened three earthquakes, but scientists said it was only a cyclical earthquake, not worrying.

Dr. Le Tu Son, Institute of Geophysics affirms: the stirring of fault zones is a very normal phenomenon. This is a very natural movement and nothing to worry about. Moreover, Vietnam is assessed as an area with few earthquakes, except for some areas such as Ma, Son La, Song Da, Lai Chau - Dien Bien fault zones .

However, scientists also emphasized that it should not be subjective because Vietnam also had strong earthquakes of 7-8-magnitude level . It is known that the Institute of Geophysics is in a state of 24 hours a day so that if there are abnormal signs, a warning message will be issued. The institute also recommends that local authorities and people have earthquakes measures to respond to and overcome the consequences of earthquakes.

According to Dr. Dao Van Thinh - Institute of Geology and Environment (Vietnam Geological Society), the North West is the most dangerous and most dangerous area of ​​earthquake in the territory of Vietnam, mainly due to transfer. modern tectonic and modern dynamics. Earthquakes are geological disasters that cause significant damage to property and lives.

Most earthquake episodes often focus along deep penetrating faults such as the Dien Bien - Lai Chau fault; Tuan Giao - Tua Chua (meridians) and Ma, Son La, Phong Tho and Muong Te rivers (northwest - southeast). Especially Phong Tho - Phu Sam Sao zone is the region with the highest earthquake density.

Dr. Dao Van Thinh said that in many cases, no matter how good the forecast is, the geological disasters, especially earthquakes, are still unexpected, suddenly appear and take place in short or extremely short periods. Only a few seconds and the consequences are very heavy.

When they occur in remote areas, rescue and rescue vehicles cannot respond promptly. Therefore, the most effective method is to propagate to the people the awareness and the will to save themselves, to prevent themselves.

Statistics in the period from 1903 to 2003, the Northwest region occurred 340 earthquakes in different large and small levels. Among them, there were 244 earthquakes of less than 4 magnitude magnets (accounting for 71.76%); 43 earthquake magnitude from 4 to 4.5 magnitude (accounting for 12.64%), there are 43 earthquakes from 4.5 to 5 richter scale (accounting for 12.64%); There are 8 magnitude earthquakes ranging from 5 to 5.5 in magnitude (2.35%) and there are only 2 earthquake magnitude over 6 Richter, one in Southeastern Dien Bien city (1935 ) and one match in Northeast of Tuan Giao and Lai Chau towns (1983) accounted for 0.58%, tremors in the heart reached level 8-9 richter.
