| 1. | This was mainly because the quake had a focal depth of approximately.
|
| 2. | The focal depth can be calculated from measurements based on seismic wave phenomena.
|
| 3. | It houses a 300 double reflector with a focal depth of 4.9 m.
|
| 4. | Previously, all earthquakes were considered to have shallow focal depths.
|
| 5. | The earthquake had a magnitude of 4.3 at a shallow focal depth of 5 km.
|
| 6. | The camera allows the photographer to set focal length to control the focal depth of photos.
|
| 7. | The magnitude of the earthquake has been estimated to be 8.4 focal depth of about 40 km.
|
| 8. | The last 2005 earthquake is the focal depth and its location with respect to the densely populated areas.
|
| 9. | Another common requirement is to take a series of images at a fixed position, but at different focal depths.
|
| 10. | On 13 April 1992, a magnitude 5.4 earthquake occurred near the city of Roermond in a focal depth of about.
