Sunday Reading
This is the inaugural post of a weekly series I promised to start that will supplement my more in depth but sporadic blogging about topical seismic events. A couple months ago I joined Twitter to broadcast some of the interesting seismic news snippets I come across daily, including lots of content that didn’t really warrant drawn out posts. As I promised then, I’m now compiling my full week of Tweeted …

Musings on seismology and earthquake hazard
Phew, I’ve been a neglectful blogger… probably to the benefit of my dissertation research. I’ve got a few interesting posts in the pipeline, so I think I’ll take what time I can to finish them, then set them up so they’re nice and distributed for you to read. In the meantime, you should all check out two cool blogs maintained by earthquake aficionado Arne Christensen, in which he compiles media …

La aplicación está disponible solo …

Earthquake early warning in action
No country would have been better prepared for such a massive earthquake than Japan. Straddling the boundaries between four converging tectonic plates, Japan is one of the most earthquake prone nations in the world, and is probably the most earthquake savvy. They have world-class networks of monitoring instruments including seismometers, tide gauges, and GPS locating stations; they routinely practice for massive quakes, which they are often visited by; and they …

More unique perspectives of the 8.9 quake
As expected, videos continue to surface from people all over Japan documenting the shaking, rattling, and swaying of everything. Below I have collected some of the more interesting sights. I recommend visiting Highly Allocthonous where Chris Rowan has summarized the which, what, where, and how of this massive quake. He’s also put together some nice little diagrams illustrating the more technical concepts. The whole country of Japan shook for a …
