Between 9.1 and 9.3.
Yes, the 9.0 magnitude earthquake caused the tsunami.

In the Indian Ocean
No. The second highest earthquake magnitude (depending on the source of the information) was either the Boxing Day 2004 Indian Ocean earthquake (magnitude 9.1 - 9.3) or the 1964 Alaskan earthquake (magnitude 9.2). The Haitian Earthquake in January 2010 had a Richter magnitude of 7.2.
5-6 recorded earthquakes have measured 9.0 or higher on the Richter scale. 1960 Valdivia earthquake; Valdivia, Chile; 9.5 magnitude 1964 Alaska earthquake; Prince William Sound, Alaska, USA; 9.2 magnitude 2004 Indian Ocean earthquake; Indian Ocean, Sumatra, Indonesia; 9.1-9.3 magnitude 1952 Kamchatka earthquakes; Kamchatka, Russia (then USSR); 9.0 magnitude 2011 Tohoku earthquake; Pacific Ocean, Tohoku region, Japan; 9.0 magnitude 1833 Sumatra earthquake; Sumatra, Indonesia; 8.8-9.2 magnitude (est.)
The second strongest earthquake in the world occurred on December 26 2004 and had a magnitude of 9.3. The epicenter was on the ocean floor near the west coast of Sumatra, Indonesia and caused a deadly tsunami in the Indian Ocean
The earthquake that occurred in the Indian Ocean on December 26, 2004, measured 9.1 to 9.3 on the moment magnitude scale, which is the modern equivalent of the Richter scale. This powerful earthquake triggered a massive tsunami that affected several countries around the Indian Ocean, resulting in significant loss of life and widespread destruction. It remains one of the deadliest natural disasters in history.
A magnitude 9.0 earthquake would likely have global impacts, causing widespread damage and triggering tsunamis across multiple regions. The 2004 Indian Ocean earthquake, with a magnitude of 9.1-9.3, is an example of how such a large quake can have far-reaching consequences.
The 2004 tsunami was caused by a massive undersea earthquake with a magnitude of 9.1-9.3 off the coast of Sumatra, Indonesia. This earthquake triggered a series of devastating tsunamis that affected multiple countries bordering the Indian Ocean.
The biggest earthquake in our century is the Indian Ocean earthquake in December 2004 with a magnitude of 9.1. But that's not exactly in the last five years, so the Sendai earthquake in Japan today (March 11, 2011) is the biggest earthquake in the last 5 years, with a magnitude of 8.9.
the Indian ocean earthquake of 2004 26th December measured 9.3 on the Richter scale. this earthquake was one of the most worst natural disasters in history. this was no ordinary tsunami but a mega-thrust tsunami.
