Frequently Asked Questions

1. What is the most common synonym for earthquake?

The most common everyday word is “quake.” In news reports and scientific stories, you will often see “temblor” or “tremor” used instead.

2. Is there a difference between a tremor and an earthquake?

Yes. A “tremor” is a very small, weak shaking of the earth. An “earthquake” can range from a small shake to a massive, destructive disaster.

3. What does “tectonic shift” mean?

A “tectonic shift” is the movement of the massive puzzle pieces of rock that make up the earth’s crust. This deep movement is what causes a typical earthquake.

4. Can “upheaval” be used for things other than earth movements?

Yes. “Upheaval” is often used to describe major, sudden changes in life, politics, or business, such as a company reorganization.

5. Why do scientists use the word “seism”?

“Seism” comes from the Greek word for shaking. Scientists use it because it sounds more formal and connects to tools like the seismograph.

6. What is the difference between a foreshock and an aftershock?

A “foreshock” is a small vibration that happens before the biggest shake. An “aftershock” is a smaller shaking event that occurs after the main earthquake.

7. What is a “megaquake”?

A “megaquake” is an informal term used to describe a massive earthquake that measures over 8.0 on the magnitude scale.
