- WHAT IS THE LARGEST MAGNITUDE EARTHQUAKE THAT SHOOK MEXICO CITY?
- On September 19, 1985, Mexico City experienced a devastating earthquake of 8.1 magnitude, with its epicenter on the Pacific coast. It is estimated that at least 10,000 people lost their lives, affecting and collapsing thousands of housing, commercial, and public service structures.
- WHAT IS THE DIFFERENCE BETWEEN THE MAGNITUDE AND INTENSITY OF AN EARTHQUAKE?
- They are scales to measure the size or impact of a tremor. The magnitude scale is obtained numerically from records obtained by seismographs and is related to the size and energy released during a tremor. The intensity scale is assigned based on the damage or effects caused to people and their constructions.

WHAT IS AN EARTHQUAKE?
An earthquake is a sudden breaking of rocks inside the Earth. This sudden release of energy propagates in the form of waves that cause ground movement.
HOW LONG DOES AN EARTHQUAKE LAST AND WHY DOES THE SSN NOT REPORT THIS DATA?
When we talk about the duration of an earthquake, we can refer to several different concepts: One is the duration of the movement perceived by humans, another is the duration of the instrumental record (which can be several minutes), and another is the time the fault movement that caused the earthquake lasted (which can be just a few seconds).
