Question
The International Deployment of Accelerometers Project at the Scripps Institution of Oceanography operates a global network of these devices. For 10 points each:
[10m] Name these devices which can be implemented using an inverted pendulum model. Stations of these devices typically use Z, E, and N to represent the vertical, east-west, and north-south high gain components, respectively.
ANSWER: seismometers [or seismographs]
[10h] Readings from seismometers are commonly used to estimate this measure introduced in a 1979 paper by Hanks and Kanamori, which is equal to two-thirds times the base-10 logarithm of M-naught minus 10.7, which is commonly adjusted to 16.1 or 9.1.
ANSWER: moment magnitude [or Mw; prompt on magnitude]
[10e] The moment magnitude has been adopted as an American and European standard due to this other scale’s tendency to underestimate the intensity of strong earthquakes.
ANSWER: Richter scale [or local magnitude scale or ML]
