Question 1

O que é um monitor sísmico em tempo real?

Accepted Answer

A real-time earthquake monitor displays seismic activity as it is detected by global seismographic networks, showing magnitude, location, depth, and time of earthquakes within minutes of occurrence.

Question 2

Como a magnitude é medida?

Accepted Answer

Earthquake magnitude is measured using the Richter scale or moment magnitude scale (Mw), which quantifies the energy released at the source. Each whole number increase represents roughly 32 times more energy.

Question 3

Quais áreas têm mais terremotos?

Accepted Answer

The Pacific Ring of Fire experiences about 90% of global earthquakes. Other active regions include the Alpide belt (Mediterranean to Himalayas) and the Mid-Atlantic Ridge.

Question 4

Com que frequência ocorrem grandes terremotos?

Accepted Answer

On average, about 15 magnitude 7.0-7.9 earthquakes occur annually worldwide, while magnitude 8.0+ events happen roughly once per year. Smaller earthquakes are far more frequent.

Question 5

Terremotos podem ser previstos?

Accepted Answer

Currently, earthquakes cannot be reliably predicted. Scientists can identify areas of high seismic risk and calculate probabilities, but precise short-term prediction remains impossible.
