What two measurements are taken during and after an earthquake?

Do earthquakes have a little shake before the big earthquake?
Yes, earthquakes can have foreshocks, which are smaller earthquakes that occur before the main event. These foreshocks can help seismologists to predict the likelihood and intensity of an upcoming larger earthquake.
Major earthquakes are sometimes preceded by smaller earthquakes called .?
before shokes
Was there foreshocks or afterscocks in the japan earthquake in march 2011?
Yes, major foreshocks preceded the earthquake on 11th March 2011 and major aftershocks succeeded the earthquake. There were hundreds of aftershocks of varying intensities, one even as great as 8 on the Richter scale causing a 10 meter tsunami.
How long before an earthquake do foreshocks occur?
It could be days or YEARS before the major earthquake. Plate tectonics are always moving.
Why do foreshocks occur?
Foreshock activity has been detected for about 40 % of all moderate to large earthquakes, and up to 70% for magnitude events >7.0. In one model of earthquake rupture, the process forms as a cascade of foreshocks, starting with a very small event that triggers a larger one, continuing until the main shock rupture is triggered.
Small foreshocks that precede a major earthquake occur?
Its when a minor earthquake is shaking next to a fault. and finally the big one happens
Were there any warnings about the 2007 Gisborne earthquake in New Zealand in 2007?
It is not possible to issue warnings about earthquakes at present as they cannot be predicted with current knowledge.It is hoped that in the future, warnings will be able to be issued for some types of earthquakes that have foreshocks (smaller earthquakes that happen before the major quake). There is no mention of foreshocks for the Gisborne 2007 quake on the Geonet website. There were aftershocks. See the related links.
Compare and contrast aftershocks and foreshocks?
An aftershock is a small earthquake that follows the main earthquake, while a foreshock is a small earthquake that often precedes, leads to, a major earthquake.
