PGS: Fairfax Urban Search and Rescue in Nepal

The Potomac Geophysical Society, November 19, 2015–directions below:

Fairfax Urban Search and Rescue in Nepal.

The description will be: After the April earthquake in Nepal, the urban search and rescue team from the Fairfax County Fire and Rescue Department responded and rescued two victims from collapsed structures.  The team is one of two search and rescue teams sponsored by the federal government to conduct international search and rescue.

John Morrison serves as a Planning Section Chief within the Urban Search and Rescue team, Virginia Task Force 1, which serves as one of the 28 domestic response teams under FEMA and as one of the two response teams under USAID/OFDA.  The planning section is responsible for situational awareness, information technology, mapping, finance and documentation while the team is deployed.  He has been a member of the team since 2003.

Meeting Room and Dining Arrangements: We meet in the glassed-in room at the back of the main dining room, The Fife and Drum. We order individually from the Club menu, which has a nice variety of dinner offerings. We pay a single bill, so we collect $25 from each member and $30 from each non-member. If a diner orders more than $20 in food and drink, he adds the amount over $20 to his contribution. The $5 overcharge goes to the Room Fee, Tax, Gratuity, and the Speaker’s Dinner. We collect on the Honor System. Reception is at 6:00 p.m. downstairs in the Old Guard Lounge. We order dinner at 7:00 p.m. The presentation is at 8:30 p.m. Please note that the meal orders will be taken at 7:00 p.m. Allow 15 minutes for security entering Ft. Myer as all civilian vehicles are searched. To ensure access to and from Fort Myer, use the Hatfield Gate, open 24 hours a day. Reservations are not necessary, however, we need a head count; so, if you wish to attend dinner, please inform Bob Fraser at 703-624-3965 or via email at fraser.robert@comcast.net. If you wish, please feel free to attend the talk without dinner. Non-members and guests are welcome. Please send changes of address or email to fraser.robert@comcast.net.

PSW: The Role of Paleoecology in Everglades Restoration

Please post the following meeting announcement:

The Paleontological Society of Washington

Wednesday, November 18, 7:00 pm, in the Cooper room (E-207A), National Museum of Natural History, Constitutional Ave. entrance

The Role of Paleoecology in Everglades Restoration

Lynn Wingard

Research Geologist /Project Chief, Eastern Geology and Paleoclimate Science Center, United States Geological Survey, Reston, VA

Restoration of the Florida Everglades is projected to take 30-50 years and the cost is currently estimated to be almost eight billion dollars. Success is contingent on restoring more natural hydrologic flow through the ecosystem and on understanding how the ecosystem will respond to projected climate and sea level changes over the next century. This talk will illustrate how paleoecologic data is guiding restoration efforts. Applied paleoecology is a reality!

Non-Smithsonian visitors will be escorted to the Cooper Room at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

PGS venue changing in 2016

The monthly meetings of the Potomac Geophysical Society (PGS) for September through December, 2015, will be held at Fort Myer Officers Club in Arlington, Virginia, as in the past.  The optional dinner cost will be discounted to $25 for members in good standing (have paid dues), and $30 for non-members.  Members and guests may attend the presentation after dinner for no charge.

Starting in January and going through May, 2016, PGS will hold its monthly meetings on the third Thursday at Chili’s/On the Border Restaurant.  The restaurant with meeting room is located at 8053 Leesburg Pike, Vienna, VA, 22182.  This location is within one mile of the Tysons Corner Metro stop, near I-495, and has free parking available.  Our meeting room is located at the back of the On the Border restaurant.  The room will hold 22 people comfortably for a dinner meeting.  The wait staff and menu will be from Chili’s.  The optional dinner cost will continue to be discounted to $25 for members in good standing (have paid dues), and $30 for non-members.  The dinner cost will cover non-alcoholic drinks, tax, gratuity, and the speaker’s meal.  Members and guests may attend the presentation after dinner for no charge.

The officers of PGS look forward to experiencing this change in venue.  Please let us know if you have any questions.

Respectfully,

Catherine Enomoto, President

PGS: Louisa, VA earthquake sequence

The Potomac Geophysical Society, October 15, 2015–directions below:

Observations on The Louisa County Earthquake Sequence.

Keith L. McLaughlin

Abstract: At 13:51:04 EDT 23 August 2011, an Mw 5.7 earthquake occurred in rural Louisa County VA, near the small town of Mineral. The MMI VIII event was widely felt in 13 states and caused an estimated $200-300 Million damage. The event has been called “The largest and most damaging earthquake in eastern US since Charleston SC 1886”.  Aftershocks continue. While the Central VA earthquake zone has a history of moderate (MMI V-VII) earthquakes, the zone has historically been sparsely monitored. Two seismic stations between 100 and 300 km of the main shock provide a tantalizing historical data set that may be successfully exploited using modern waveform cross-correlation methods.  The main-shock was a complex rupture and the aftershocks are distributed over a significant volume with a range of focal mechanisms. These factors present a unique challenge to developing correlation-based methodologies to “mine for aftershocks” and search for un-reported events. I will present work in progress using these developing methods to investigate the Louisa Sequence.

Dr. McLaughlin’s specialty is physics-based statistical analysis of geophysical sensing (seismic, acoustic, and EM). He developed methodologies for event magnitude estimation, localization accuracy assessment, seismic, acoustic and EM adaptive signal-processing and physics-based target-based multi-mode multi-node fusion (M3NF) for MASINT exploitation architectures. Over the last three decades he worked on ground motion prediction (earthquake, explosion, machinery, vehicles, …), seismic and infrasound location, event discrimination, yield estimation, geothermal exploration, and persistent monitoring of human activities from unattended ground sensors. He was co-PI with VaTech under the DARPA Heterostructural Uncooled Magnetic Sensor (HUMS) program. He served as the PI and PM for the DTRA “IMS Group 2 Location Calibration Consortium”. He served as domain expert and US delegate to multiple bi-lateral and multi-lateral international conferences and workshops.
