Tremor

While much of the world was gazing at a lunar eclipse, I was experiencing my first Mexican earthquake. It was mid-afternoon and things shook in the office for a few seconds. We took it seriously and lined up (comically) along a wall before convening in the park outside. It was only 5.4 - I experienced worse, and more frequently, in Tokyo - but it was nonetheless a reminder that we're in a volatile area. This autumn will be the 30th anniversary of Mexico City's big one which killed over 10,000 people.
