- M7.0,Western offshore South Island, New Zealand in 2025/03/25
- M7.7,West coast of South Island, Myanmar in 2025/03/28
The plotted positional relationship of them is as below,
These positions are almost on the same line. Even though the line isn't the shortest distance on the earth as sphere, I guess it may have some meaning.
