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.
Following the 6.3 magnitude earthquake in 2011, Christchurch experienced thousands of aftershocks. These aftershocks continued for several years, with some reports estimating over 10,000 aftershocks in total.
On March 11 alone, there were 200+ aftershocks. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.9.
The Christchurch earthquake of 2011 had over 13,000 aftershocks.
The correct Date of the original earthquake was March 9th not 11th.The aftershocks are still continuing. Even today (Monday, March 14, 2011) a 6.2 aftershock has hit Tokyo, and there are fears that aftershocks as large as a 7.0 could still hit.Note:6.2 and 7.0 in their own right are earthquakes, but because they came after the upgraded 9.0, they are classed as aftershocks.At this moment no-one has released a time for the first aftershock there have been over 275 of magnitude 5 or over.The earliest reference I can find for an aftershcok would be at a 6.1 at 3.15 am local time on the 10th of March followed by two more.AdditionallyOn March 11 alone, there were 200+ aftershocks immediatelyy following the 9.0 earthquake. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.0.
The last earthquake that occurred in Japan was on the 1st of January 2012 with a magnitude of 6.8 on the Richter Scale. The earthquake you probably heard about happened on the 11th of March 2011 which had a tsunami following it. The magnitude for that was 9.0. This earthquake had four aftershocks which happened on the 11th of March 2011, 7th of April 2011, 11th of April 2011 and the 10th of June 2011. the magnitudes for these were 7.1, 7.1, 7.1 and 7.0.
On March 11, 2011 alone, there were 200+ aftershocks. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.9. As of August 10 there were 4,308 earthquakes in or near Japan for year 2011 according to the USGS earthquake data (not including small quakes under M 3.0) with March the most active month of the year. That's on average over earthquakes 19 per day.
On Thursday March 10, 2011 a series of aftershocks rattled Japan (including a magnitude 6.6 quake) after the magnitude 7.3 quake hit the northeastern Honshu island March 9, said the Japan Meteorological Agency. On March 11, 2011 alone, there were 200+ aftershocks. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.9.

On March 11, 2011 in Japan they had an earthquake and a tsunami. A magnitude 9.0 earthquake rocked Japan at 2:46 p.m. local time followed by many aftershocks. The major earthquake struck about 15 miles. Also because of the earthquake and the aftershocks a tsunami was set off. The earthquake occurred off the coast of Honshu. It was the strongest earthquake to ever hit Japan. It was one of the top five largest recorded earthquakes in the world. The waves of the tsunami were as high as 35 feet. This was reported in several different Northern regions of Japan. There were 8,649 people who were confirmed dead, 21,911 people who are still missing till this day. There were 19 aftershocks reported
There was a major earthquake in Christchurch, New Zealand on February 22, 2011, with over 10,000 aftershocks reported in the following months. The main earthquake caused significant damage and loss of life, and the aftershocks added to the ongoing challenges faced by the community.
The shaking of the main earthquake (which came after some tremors) lasted for 20 seconds. In addition, there were 1,320 aftershocks.
