We just learned about the Remotely Triggered Earthquakes.
Another type of earthquake is the Slow Earthquake.
The earthquakes that we see in movies or see on TV are usually a fast earthquake that is over in just a few seconds or minutes.
Scientists have now found out that sometimes there are earthquakes that last for hours, days or even months!
These are called Slow Earthquakes, and they are very quiet or maybe not even noticed except by some special scientific tools used to measure earthquakes.
