According to the official determination of China Seismological Network, a magnitude 6.0 earthquake occurred in Chile at 0:36 on September 27, Beijing Time (11:36 on September 26, local time). The focal depth was 110 km, the epicenter was located at 40.75 degrees south latitude and 71.99 degrees west longitude.
What is the magnitude of the 6.0 earthquake?
Earthquake magnitude is divided into nine, generally less than 2.5 magnitude earthquake people do not feel, more than 2.5 magnitude people feel, more than 5 magnitude earthquake will cause damage. Earthquake magnitude for short.
- Generally, earthquakes with magnitude less than 1 are referred to as ultramicro-earthquakes.
- Weak earthquakes or microseisms with magnitude M (> 1) or less than magnitude 3 are called weak earthquakes or microseisms.
If the source is not very shallow, such earthquakes are generally difficult to detect.
- Sensitive earthquakes are those whose magnitude M is greater than or less than 4.5.
Such earthquakes can be felt, but generally do not cause damage.
- Medium-strong earthquakes (such as the 9.7 Yiliang earthquake) with M (> 4.5) and M (> 6) are called moderate-strong earthquakes.
It belongs to the earthquake that can cause damage, but the degree of damage is also related to the depth of the focal point, epicenter distance and other factors.
- Strong earthquakes (e.g. 8.3 Ludian Earthquake and 2.6 Kaohsiung Earthquake) are those whose magnitude is greater than or less than 7.
- Large earthquakes (such as the 8.8 Jiuzhaigou earthquake, the 4.14 Yushu earthquake, the 4.20 Ya’an earthquake, and the 7.18 Kamchatka Peninsula earthquake) are those with M (>7) and M (>8).
Large earthquakes (such as the 5.12 Wenchuan Earthquake and the 3.11 Japanese Earthquake) with magnitude 7.8 and above are called huge earthquakes.
What should we do in case of an earthquake?
Although earthquakes are unavoidable and uncontrollable for human beings at present, as long as we master some skills, we can also minimize the damage from disasters.
- Don’t rush in a big earthquake
Destructive earthquakes mean only 12 seconds from people’s feeling of vibration to buildings being destroyed. In this short period of time, you must not panic. You should make a quick decision to ensure safety according to your environment. If you live in a bungalow, you can run outside the door quickly. If you live in a building, do not jump, should immediately cut off the switch, turn off the gas, temporarily shelter in the toilet and other small span areas, or under tables, beds, etc., quickly evacuated after the earthquake, in order to prevent strong aftershocks.
- Most people find shelter first.
Schools, shops, theatres and other places where people gather are most afraid of panic in case of an earthquake. They should immediately hide under desks, chairs or solid objects, and then evacuate orderly after the earthquake. Teachers and other on-site staff must calmly instruct people to take shelter in situ and never take the lead in running around.
- Keep away from dangerous areas
If you encounter an earthquake on the street, cover your head with your hands and quickly move away from the building to the street center. If you encounter an earthquake in the suburbs, be careful to stay away from cliffs, steep slopes, riverbanks and high-pressure lines. The running cars and trains should stop immediately.
- Be buried to preserve physical strength
If the earthquake is unfortunately buried in ruins, we should try to remain calm and try to save ourselves. When it is impossible to get out of danger, we should keep our strength, try our best to find water and food, create living conditions, and wait patiently for rescuers.
