The Earthquake Information and Tsunami Warning Center assessed this earthquake as not posing a natural disaster risk. They are continuing to monitor the situation.

The Institute of Earth Sciences reported today that five more earthquakes, ranging in magnitude from 2.5 to 3.4, occurred in Mang Ri and Mang But communes ( Quang Ngai province). These earthquakes are classified as level 0 natural disaster risk.

According to a preliminary report from Quang Ngai province, the earthquake caused damage to two classrooms, including roof damage, and cracked walls in four classrooms, nine boarding rooms, and two households in Mang But and Mang Den communes.

In Vietnam, earthquakes measuring between 3 and 3.9 magnitude are considered weak. Some people may feel an earthquake, but it rarely causes damage. Objects in the house might be noticed shaking.

Each year, over 100,000 similar earthquakes occur worldwide.

Earthquakes of magnitude 4-5 are considered mild earthquakes. When an earthquake occurs, objects inside the house shake and make noise. Many people feel the earthquake. Those outside the house feel slight tremors.

Generally, these earthquakes cause little to no damage. They rarely cause moderate to significant damage. Some household items may fall.

The average frequency of occurrence worldwide is 10,000-15,000 matches per year.
