Oct 18, 2023 · On the Richter scale, the Alaska quake was "bigger" having a M S of 8.6 compared to the M S of the Chilean quake of 8.5. However, in measuring the seismic moment, the Chilean quake was larger, giving M w of 9.5 versus the M w of 9.2 for the Alaskan earthquake. The reason is that the Chilean earthquake released more energy, but in the Alaskan ... 13 de ago. de 2015 ... Charles Richter made a huge mess of the way that seismologists measure the strength of a quake, and it's making our lives hell.Scientists use seismic waves to measure how big an earthquake is. They use a device called a seismograph to measure the size of the waves. The size of the waves is called the magnitude. To tell the strength of an earthquake scientists use a scale called the Moment Magnitude Scale or MMS (it used to be called the Richter scale).That 0.5 difference is much more meaningful than you'd think. Another large earthquake struck Nepal today. It was estimated as a magnitude 7.3 by the United States Geological Survey. Due to the logarithmic way earthquakes are measured, this...
