It is remarkable observing how very active the Earth has been in just the last 24 hours (06092018 to 07092018). Around the Ring of Fire, 4 moderate to major earthquakes have occurred. A MAJOR M7.9 earthquake shook Fiji – the impressive focal depth was >650km deep inside the Earth! Following seismic activity in Fiji, earthquakes occurred in Panama (M5.6), Ecuador (M6.2) and Chile (M5.8). LOOK at the differences in amplitude between the events. Which are smaller? larger? similar? What other key piece of information would be useful when answering this question?
24 Hours of Global Shaking, September 6-7, 2018.
