Japanese Earthquakes and 24-hour Battery Backup


In 2011, following the Great East Japan Earthquake, Japan's Ministry of Internal Affairs and Communications convened a study group composed of the major mobile providers and decided to fortify battery backup for 2,000 locations across the country. Battery backup time was increased to 24 hours for these locations, which are mainly city halls and prefecture headquarters.

The most recent large earthquake (magnitude 7.0) in Japan happened 1 kilometer west-southwest of Kumamoto City. The screenshot below is from Softbank Mobile's site. The Kumamoto City Hall and Prefecture office locations are highlighted in red.

Those locations are listed on each provider's site. Here is an example (in Japanese).

Beautiful California

California. It's the last week of April -- still snowing in the mountains, but dirt-dry in Owens Lake, off Highway 395 in the Eastern Sierra. At the other end of the state, the rocky shore of the north coast near the border of Oregon. Finally, steel sculptures northeast of Lassen National Park near Burney.
