The explosion in the ground can be caused by volcanic lava

Experts from the Vietnam Geological Society said that the loud explosions in the ground downstream of Song Tranh 2 hydropower dam (Quang Nam) could be caused by volcanic lava entering the cave, hollow pillars filled with water in the ground. .

Before the underground phenomenon of the downstream of Tranh Tranh 2 hydropower project in Bac Tra My district (Quang Nam) continuously released explosions, scientists had to dissect the cause.

Geological doctoral Le Huy Y, Vietnam General Geology Division, said that underground volcanic lava flows could penetrate into caves and niches, hollow columns filled with water in the ground, emitting loud and explosive explosions. earthquake. According to him, from this phenomenon, it can be seen that the geological area of ​​Tra My district is having the tectonic activity of the blocks of entering young young volcanic farm.

Dr. Y proposes local and functional agencies to examine and survey carefully to accurately and fully evaluate all tectonic faults, fault points and ancient volcanic throat distributed in the surrounding area. the body of the Song Tranh 2 body is dammed. At present, Tra My region's faults on the geological map are lacking. If there is an epicenter near the dam body, it will bring serious consequences for residents below the downstream of Tranh Tranh 2 hydropower project.

Talking to PV, professor and doctor Cao Dinh Trieu, expert of Geophysical Institute affirmed that aftershocks in the downstream area of ​​Bac Tra My were under 3.5 richter, stimulating earthquake form. It is not possible to endanger the life and property of people in the region. Geophysical Institute has sent professional staff to closely monitor the earthquake in this locality.

According to Mr. Trieu, based on the geological drawing that was measured in Bac Tra My district, the fault zone in this locality is quite strong. Therefore, with the continuous underground phenomenon exploded in the last long time, Quang Nam province should propose specialized agencies to study in order to help people actively prevent it when there is a problem."Do not let the time when" water comes to dance ", then I do not keep up," Mr. Trieu emphasized.

In 2009, Quang Nam province cooperated with the Vietnam Institute of Science and Technology to carry out the research project 'Assessing the status quo and warning zone of risk details, proposing solutions to prevent soil cracks , landslides as a scientific basis for planning sustainable socio-economic development in Quang Nam province. The topic is chaired by Dr. Pham Van Hung, Institute of Geology.

The research results show that, landslides and landslides in mountainous districts of Quang Nam province are increasing rapidly. Scientists have delineated the landslide risk warning scheme in the province with 5 dangerous levels. In particular, the area is very high risk of landslides including 7 districts, particularly Bac Tra My is located in the area of ​​landslide warning in the highest group.

Experts have recommended Quang Nam province to monitor, forecast and warn geological disasters that have occurred and are at risk; planning management, people to minimize risks of people and property.

Before 2 am on November 23, residents of Tra Tan, Tra Son and Tra My towns for the fifth time in the past few months noted a loud explosion in the ground that shook their houses. Quang Nam Department of Science and Technology has sent a delegation to verify and check this phenomenon. Mr. Pham Ngoc Sinh, Deputy Director of the Department said that he proposed the Ministry of Science and Technology to invite experts to monitor and research, find the cause of the earth shaking and make an explosion.
