Iwate Prefecture may be known as a place devastated by the 2011 Great East Japan Earthquake, but it’s coming back better and stronger than ever.
Iwate is a large prefecture on the northeastern coast of Honshu, Japan’s main island. The southern city of Hiraizumi contains a rich architectural legacy from its period as a political center in the 11th and 12th centuries, including Chūson-ji Temple and the adjacent Mōtsū-ji Temple. Northeast, the city of Tōno was the birthplace of many folk tales, now recounted in traditional surrounds at its Old Tales Village.

Contributing Correspondent Lizzie Wade talks with host Sarah Crespi about the role of inequality in past pandemics. Evidence from medical records and cemeteries suggests diseases like the 1918 flu, smallpox, and even the Black Death weren’t indiscriminately killing people—instead these infections caused more deaths in those with less money or status.
Also this week, Aaron Wech, a research geophysicist for the U.S. Geological Survey at the Alaska Volcano Observatory, joins Sarah to talk about recordings of more than 1 million earthquakes from deep under Hawaii’s Mauna Kea volcano, which hasn’t erupted in 4500 years. They discuss how these earthquakes, which have repeated every 7 to 12 minutes for at least 20 years, went undetected for so long.
This week, a method for predicting follow-up earthquakes, and the issues with deep learning systems in AI.
