Shallow 5.4 Magnitude Quake Hits Indian Ocean

• An earthquake of magnitude 5.4 struck the Indian Ocean on December 9.
• The earthquake occurred at a shallow depth of 10 km, increasing susceptibility to aftershocks.
• This follows a magnitude 4.8 earthquake in the same region on December 2.
• The Indian Ocean region has a history of significant seismic activity, including the devastating 2004 Sumatra-Andaman earthquake and tsunami.

Why It Matters: It underscores the Indian Ocean's vulnerability to dangerous shallow earthquakes.
