Bad Day Fishin’

It is said that  “A bad day of fishing is better than a good day of work”.  I won’t argue, but if you were trolling for trout at Chehalis Lake, British Columbia on December 4, 2007, you’d have had a bad day. Chehalis Lake, 50 miles east of Vancouver is a lovely spot nestled in the mountains. Prior to that date, it was known mostly to fisher folk and 4 wheel drive enthusiasts.

Update on the M6.5 Namie, Japan Earthquake of July 12, 2014

It is interesting to compare the pre- and post- event forecast probabilities for the Namie, Japan earthquake.  As readers of this blog will know, probabilities in the forecast here change when a large event occurs.  For the M6.5 earthquake that occurred last saturday, probabilities for M>6 earthquakes decreased, whereas probabilities for the M>7 earthquakes increased slightly.  The changes can be seen in the attached comparison screenshots.

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.

Tajikistan-Afghanistan-Pakistan Earthquakes

Recently there have been a series of M>6 earthquakes in Tajikistan-Afghanistan-Pakistan, Central Asia.  We can use the hazard viewer to evaluate the risk, which appears to be quite high at this time.  A screenshot of the selected region is below, together with 3 recent M~4 earthquakes.

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
