USGS Summary: M 7.7 Earthquake, Mandalay, Burma (Myanmar)
United States Geological Survey
On March 28, 2025, at approximately 12:50 PM local time, a powerful magnitude 7.7 earthquake struck near Mandalay, the second largest city in Burma (Myanmar), home to 1.2 million people. The shallow depth of the quake, about 10 kilometers (6.2 miles), resulted in intense shaking that devastated the region and was felt as far away as Bangkok, Thailand. The link above is to a USGS article page. You can see the USGS events page for more information.

Helium: A Byproduct of the Natural Gas Industry
Geology.com
Helium Blimp: Most people have heard of helium being used as a lifting gas for weather balloons, blimps, and party balloons. These are very minor uses of helium. The use that consumes more helium than any other is cooling the magnets in MRI (magnetic resonance imaging) machines in medical facilities. Goodyear blimp photo by Derek Jensen.
