| 1. | A sufficiently large earthquake magnitude and other information triggers a tsunami warning.
|
| 2. | Earthquake magnitudes are calculated according to ground motion recorded on seismographs.
|
| 3. | There is no direct connection between an earthquake magnitude and a resulting tsunami.
|
| 4. | Earthquake magnitudes are measures of earthquake size calculated from ground motion recorded on seismographs.
|
| 5. | The scales of earthquake magnitude, which measure earthquake size calculated from ground motion recorded on seismographs:
|
| 6. | The size obviously dictates the potential earthquake magnitude.
|
| 7. | Allbaugh said preliminary assessments suggested damage was light, though the earthquake magnitude was " pretty serious ."
|
| 8. | The earthquake magnitude 7.5 hit the Pichilemu, O'Higgins Region area on April 8, causing two more deaths.
|
| 9. | The maximum creditable earthquake magnitudes are 8.25 for the San Andreas fault and 6.75 for the Healdsburg fault.
|
| 10. | The scale came about in 1969 _ 34 years after seismologist Charles Richter invented the earthquake magnitude scale.
