The other answer is incorrect. The correct answer is stationary.
Answer: Super cell thunderstorm
Explanation: When cold and warm air masses collides with each other, balancing the total air mass, then this condition is called the stationary front. This front often creates heavy flooding occurring in a particular region with heavy thunderstorm, which is known as the super cell thunderstorm.
Super cell thunderstorm are enormous, destructive storms which are formed due to the instability in the air masses, moisture content in the air masses, wind speed as well as lifting mechanism of the air mass. It is the strongest of all the thunderstorm types.
Assuming this involves another form of shifting tectonic plates, the answer would be earthquakes. Another form of the question is asking for continental drift.
