A 6.2-magnitude earthquake occurred in Vanuatu, a South Pacific island country. What impact might such an earthquake have?

On 20021February 18, an earthquake of magnitude 6.2 occurred near Vanuatu, an island country in the South Pacific, with a focal depth of about 10 km. At present, there are no reports of casualties. South Pacific island countries are small in land area and sparsely populated. Vanuatu, a South Pacific island country, is located in the volcanic seismic belt around the Pacific Ocean. The collision between the Indian Ocean plate and the Eurasian plate leads to frequent crustal activity.

Earthquake is a natural phenomenon that the earth's crust vibrates in the process of rapidly releasing its own energy. On the earth, the mutual extrusion and collision between plates caused the rupture and vibration at the edge and inside of plates, which is one of the main causes of earthquakes. Another reason is earthquakes caused by the influence of different geological environments. According to incomplete statistics, 85% of earthquakes in the world occur at plate boundaries.

The earthquake with a magnitude of 6.2 is a strong earthquake, which will cause the destruction of buildings and the collapse of houses. It will also cause the bridge section and the ground to crack and collapse, thus affecting the traffic rescue problem. Earthquakes can also cause damage to natural objects such as mountains, such as landslides and tsunamis. When an earthquake happens, people will feel extremely obvious shaking. Therefore, the earthquake will not only cause casualties, but also do some harm to people's lives and property. Moreover, after the general earthquake, the epidemic will spread more seriously. Moreover, when an earthquake occurs, there will be many aftershocks in a short time. In order to prevent the occurrence of earthquakes, we must do a good job in defense to reduce the impact of earthquakes.

If there is an earthquake in the building, don't try to escape from the building, because there is only 12 seconds to escape and feel the earthquake, and the time is too late. The safest and most effective way is to get under the bed and table quickly and protect your head with bedding, pillows and other objects. When the earthquake stops, leave the building as soon as possible and move to a safe place. Never hide under the balcony or window. Otherwise, when buildings collapse, balconies and windows are the first places to be impacted and damaged. If there is an earthquake in public places, keep calm, stay away from some tall buildings, telephone poles, billboards and bridges, and don't run into buildings to avoid danger. Improvise to ensure that you are in a relatively safe situation. In the worst case, after the local earthquake, you should cover your nose and mouth with clothes to prevent the smoke generated by the collapse of houses caused by the earthquake from entering your nose and mouth. We should conserve our physical strength, create living conditions and wait for rescue.
