A 6.3-magnitude earthquake struck near Alaska on Monday, serving as a stark reminder of the region's seismic activity. Fortunately, a tsunami warning wasn't issued. This event follows a 6.0-magnitude quake that shook Anchorage in November of last year. Alaska experiences nearly a magnitude 7 earthquake annually, making it the most earthquake-prone state in the U.S.

Why it matters

The recent Alaskan earthquake coincides with a growing global focus on protecting critical infrastructure from both natural disasters and evolving security threats. This is exemplified by the Reserve Bank of India's (RBI) establishment of a high-security data centre in Bhubaneswar, Odisha, to host core computing systems supporting currency management, payment and settlement operations, and regulatory data functions.

The details

The RBI deliberately chose Bhubaneswar for its modern data centre due to its strategic advantages, including its distance from potential cross-border threats and its location outside high seismic risk zones. This layered security approach, which includes physical location, network isolation, and robust infrastructure, is becoming increasingly common among central banks and financial institutions worldwide as they prioritize data security and operational control.

What’s next

The USGS Alaska Science Center will continue to provide data and research on natural resources, natural hazards, and ecosystems in Alaska to support informed decision-making regarding infrastructure development and disaster preparedness.

The takeaway

This earthquake serves as a reminder of the importance of building resilient infrastructure that can withstand natural disasters, particularly in seismically active regions like Alaska. The RBI's approach to data centre security, prioritizing physical location, network isolation, and robust infrastructure, highlights a broader trend among organizations to enhance operational control and mitigate risks from both natural and human-made threats.
