How long does a new technology last in the modern world? The CD only lasted (as a mainstream technology) for 2 decades before its replacement (MP3 files) came along. DVDs may have an even shorter life before streaming video replaces them. The analog TV lasted less than a century, as did the CRT screen.

The agency reports that booming sounds were heard in Hvolsvöllur, which is about 20 miles (32 kilometers) west of the eruption site, this week.
Surprisingly though, the impressive geological phenomena had very little impact on public health, aside from keeping Europeans with respiratory conditions on higher alert than usual.
