Members of ASCE (American Society of Civil Engineers) have provided earthquake assistance for both the September and February earthquakes.
One member, David Biggs, was in Christchurch delivering a seminar on structural engineering and seismic forensics on the 22nd of February. Another, Roberto Leon, arrived in Christchurch on the 15th of February to begin a teaching fellowship at Canterbury University. Other members came to Christchurch in April to assist in the assessment of buildings in the central city.
Some of these engineers kept daily journals of their experiences, mixing professional and personal observations and experiences. Their technical observations on assessment processes and building performance make interesting reading, as do their general comments on people and places. Compelling reading.
The journals are available online here.
