Walter, Glenn and Capt. Dennis installed the fourth seismographic station.  Steve visited a school and the Killick clinic.  Justin visited eight school sites and a clinic, including a total of 20 individual structures.  Marc stayed at the embassy and wrote a lot of e-mail.

Walter and Major Dennis identified a new site for the fourth strong-motion instrument, but the instrument blew a fuse when it was attached to the car battery.  They will return to the site tomorrow (Saturday) and try again.  Steve and Justin assessed buildings again with Army Corps engineers and will do the same tomorrow. 

Marc and Glenn flew to Cap Haitien (north Haiti) with Sgt Cruz and Pvt Dewberry to evaluate whether the port has seismic damage and the potential to serve as an alternate to the PaP port, which is closed.  The photos are from Marc and Glenn's trip.

Thursday, January 28th

A busy day today. Walter installed two more strong-motion instruments south and west of PaP. Justin and Steve embedded with two separate teams to assess the safety of buildings. Glenn and Marc assessed four "bridges", which turned out to be box culverts. On the way to the bridges, we saw numerous destroyed buildings. We also stopped by the National Palace and the Cathedral.

Update from Haiti

Everyone,

A quick update from Haiti. Going out soon.

Camped outside of Embassy.

Met GIS folks this morning. Impressive capabilities. There are at least five parallel efforts on damage assessment. Focus now is on Indigenous Displaced Peoples (IDP).

Glenn and Steve going to port with Colone Cintron and Navy Captain. After functioning for a while, port down again as piers have sustained additional damage.

Marc and Justin going with Army engineers. Will meet with UN group this afternoon to discuss needs for engineers. Will meet with U.N. emergency engineering group too this (Andre, Reggie).

Walter has temporarily installed the first ground- motion station in Haiti at the embassy. Today, he will install an instrument permanently on the grounds. Good support for installing more instruments, even south of PaP.

More later...

Briefing of General Fraser, SOUTHCOM

Our team spent the day at Homestead AF base near Miami waiting for a flight to PaP.

At around 5 pm, Lieutenant Colonel Woolwine requested that we meet with General Fraser (Commander of SOUTHCOM) to brief him on our activities and respond to some of his questions about the seismic situation. He is mainly concerned about the safety of his troops. After meeting with General Fraser (and Colonel Sweeney), we promised to make a similar briefing to the staff in Haiti. The outline of the presentation is provided below.

One nice result of the briefing was that our priority was raised (from 3 to 1) and we will be flying to PaP at 8:30AM tomorrow morning using the General's plane. Thank you to General Fraser, as well as soldiers, airmen and officers of SOUTHCOM.

Here is an overview of the presentation.

USGS/EERI Team
• Marc Eberhard, University of Washington (NEES)
(team leader, structural engineer)

• Steven Baldridge, Baldridge and Associates (ATC)
(structural engineer, ATC instructor)

• Justin Marshall, Auburn University (EERI)
(structural engineer)

• Walter Mooney, (USGS)
(seismologist)

• Glenn Rix, Georgia Tech, (GEER)
(geotechnical engineer)

Mission Goals
1. Locate source of earthquakes (install seismometers, triangulate)
2. Assess and document damage (ports, buildings)
3. Support SOUTHCOM (briefings, after-action reports ….)
4. Establish ground truth for satellite images of damage
5. Support MINUSAH-UN Emergency Engineering Services (Filiatrault, group leader appointed by special envoy)
6. Inform USAID, State Department, USGS and engineering organizations (EERI, ATC, GEER)

Seismic Forecast
Magnitude Probability of One or More Earthquakes Exceeding this Magnitude from 1/21 to 2/20
M 7 3%
M 6 25%
M5 90%

Introduction (continued)

The Geoengineering Extreme Events Reconnaissance (GEER) Association, with support from the National Science Foundation, is sending a team to Haiti to investigate the geotechnical effects of this earthquake. The team will leave the US on January 30 and stay for one week.

The Haiti earthquake, which was a strike-slip Mw = 7 event that affected ground near the margins of a bay, represents a common earthquake scenario in the US and throughout the world. This earthquake generated soil liquefaction and ground failure along the coastline and severely affected critical facilities, such as the country’s main port. It will also be important to understand how soil and geologic conditions influenced the damage patterns across the City of Port-au-Prince.

Participating in the investigation are:

Mr. Jeff Bachhuber (engineering geologist, Fugro/William Lettis and Associates)

Prof. Brady Cox (geotechnical engineer, University of Arkansas)

Mr. Jim French (geotechnical engineer, AMEC/Geomatrix)

Prof. Russell Green (geotechnical engineer, Virginia Tech)

Prof. Scott Olson (geotechnical engineer, University of Illinois)

Prof. Glenn Rix (geotechnical engineer, Georgia Tech, travelling with EERI/USACE team)

Mr. Oscar Suncar (geotechnical engineer, University of Texas)

Mr. Donald Wells (engineering geologist, AMEC/Geomatrix).

These engineers and scientists will work with teams organized by the Earthquake Engineering Research Institute (EERI), U.S. Geological Survey (USGS), ASCE TCLEE, U.S. Army Corps of Engineers (USACE), Pacific Earthquake Engineering Research (PEER) Center, and others. Information on GEER is available at http://www.geerassociation.org/
