A magnitude 7.3 earthquake in Kyushu, Japan, a magnitude 7.2 earthquake in Myanmar, a magnitude 7.1 earthquake in Afghanistan, and multiple magnitude 7.0 earthquakes in the waters off the island of Sumatra in Indonesia in a month . How to explain the recent strong earthquakes, are there any correlations between them? Has the Earth entered the seismically active period? In this regard, both Chinese and foreign experts believe that any conclusion needs to be supported by scientific evidence. However, whether it is statistical significance or specific research, it is not yet possible to determine whether the magnitude and frequency of global earthquakes are beyond the normal range, and whether there is a correlation between them. It cannot be concluded, but it is necessary to study some vigilant areas and maintain vigilance. The following options are best for text titles:. ['Earth has entered vibration mode.', 'Has the Earth entered vibration mode?', 'The earth is about to go into vibration mode.', 'Earth does not enter vibration mode.']
