Magnitude 6.5 Japan Earthquake

We have only been here in Kyoto and Sendai, Japan, 10 days and so far have experienced a super typhoon (Neoguri) and now an earthquake.  This morning, I went down to the 26th floor of our hotel here in Sendai, to photograph the rising sun.  Just before 4:00 am, the building started moderate shaking, which continued for about 20 seconds.  It turned out to be a magnitude 6.8 earthquake (later downgraded to a magnitude 6.5 event) in the trench.  I am here to give a series of lectures at Tohoku University on earthquake forecasting, so it was timely.  No damage or injuries, and no significant ts

The earthquake occurred on the Arizona side of the New Mexico-Arizona border.  Its an interesting event inasmuch as the seismicity in the area seems to be increasing, even though the forecast probabilities are fairly low.  Below is a map with a circular selection region.

Markets and Earthquakes

A couple of years ago, a New York Times story described new research that indicates financial markets bear remarkable similarities to earthquakes.  Well, we took this idea and ran with it, the result being Seismic Funds LLC.  Open Hazards serves as an advisor to the trading arm at Seismic Funds.  I am happy to report that in 2012, trading real money, the fund was up about +14.5% (before fees).  In 2013, the fund was up about +32% (before fees).  And so far year to date (YT

Today, June 1, is the First Day of Hurricane Season 2014

This is supposed to be an El Nino year, as the forecast below for October-December 2014 shows.  Forecast is from the International Research Institute for Climate and Society of Columbia University.  Wind shear in El Nino years tends to be higher than average, and inhibits the formation of tropical cyclones.

Roman Holiday

If you have ever holidayed in Rome, probably you took a side trip to the Alban Hills, 15 miles south of the City.  The Alban Volcano Complex has been a get away spot for Romans for 1000s of years. Emperor Caligula took his mammoth ‘pleasure ship’ out for summer night spins around Nemi Lake in one of the Alban craters.  To escape city heat, Popes have retreated to their summer home at Castel Gandolfo above Albano Lake since 1700.
