Question 1

เครื่องตรวจวัดแผ่นดินไหวแบบเรียลไทม์คืออะไร?

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

วัดขนาดแผ่นดินไหวอย่างไร?

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

พื้นที่ใดเกิดแผ่นดินไหวมากที่สุด?

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

แผ่นดินไหวใหญ่เกิดบ่อยแค่ไหน?

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

สามารถทำนายแผ่นดินไหวได้หรือไม่?

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.
