Our next issue will mail this week. As always, it's full of interesting articles, including one that's leading the Hit Parade on our website, Using Google Earth by Ken Mills. Also popular is Wendy Lathrop's roundup of how FEMA deals with the property behind levees. We also have a new columnist, whom you can read about in my editorial below.
In the Honshu Earthquake, initial reports indicate that the entire island moved horizontally by as much as eight feet and vertically by a lesser amount. Japan has one of the densest RTNs on the planet, so the scientific analysis will be fascinating. A preliminary analysis from the Graduate School of Environmental Studies at Nagoya University is available below in the Spotlight.
The biggest news in our industry (other than the terrible events in Japan) continues to be the LightSquared threat to GPS signals. An enormous coalition of stakeholders are uniting to ensure that the new 4G broadband network will not interfere. Gavin Schrock has continued to follow this, and in addition to drawing the cartoon below, has written Three Possible Scenarios for Broadband versus GPS.


Adding to the brouhaha are numerous sky-is-falling reports—mainly from the UK—about how vulnerable GNSS signals are, how dependent we've become on them, and what will happen economically if we don't have them. Last week, we even heard that the North Koreans had jammed South Korean military GPS devices. Stay tuned to as we track the latest developments.

I'm off this week for SPAR in Houston. SPAR is always great because of all the new technology on display and in the sessions. And because LiDAR continues to be one of the bright spots in the measurement and positioning industry, I'm sure I'll have plenty to say after the event! Last year's recap is HERE.
As always, please don't hesitate to contact me if you've got a project or story you'd like to share. Thanks for your support.
Until next time,
Marc Cheves, LS

feature Honshu Earthquake: A PDF of the preliminary analysis by Takeo Ito, Kazuhiro Ozawa, Tsuyoshi Watanabe, and Takeshi Sagiya from the Research Center for Seismology, Volcanology, and Disaster Mitigation in the Graduate School of Environmental Studies at Nagoya University is available HERE.

Excerpt from the PDF: Fig.2 shows the estimated slip distribution. The maximum fault slip is about 10m, east off the Ojika Peninsula (~38.5N). The estimated slip area extends over about 400km in the North-South, and about 200km in the East-West direction.

Fig.3 and Fig.4 show comparison of observed (black) and calculated (white) data for horizontal as well as vertical components. The model is still preliminary and fails to reproduce vertical displacement pattern in the northern half. Because of the a priori constraint applied, the estimated seismic moment should be considered as the lower limit. We will continue the effort to improve our model.

Note: All four figures are in the PDF in a more-readable form.
