Dear colleagues,
If you are working on liquefaction and/or lateral spreading investigations and mapping, please consider submitting an abstract to the below session for the 2018 SSA annual meeting. Details about the session are below. Abstracts are due by 24 January. Thanks.
Urban Liquefaction and Lateral Spread Investigations and Mapping
Liquefaction and lateral spreading are major coseismic geohazards that have an especially large impact on lifelines, in particular when they occur in urban areas. A number of recent events (e.g. Christchurch, New Zealand and the recent 2017 Mexico City event) demonstrate that further geological and geotechnical investigations and models are required to better understand where liquefaction and lateral spreading will take place in order to avoid or design to mitigate these coseismic hazards. This session focuses on urban liquefaction and lateral spread investigations and mapping efforts to better understand occurrence and recurrence of this strong-ground motion derived geohazard. The field of liquefaction hazard mapping has advanced substantially since initial projects in the 1980s through 1990s established the practice. This session is focused on reviewing advances brought about by documentation of effects from earthquakes over the past few decades and ongoing advances and application of new technologies and analytical understanding.
Specific topics of interest include integration of remote sensing exploration (lidar, satellite observations, etc) of recent liquefaction and laterals spreading, in addition to geological (trenching), geotechnical (CPT and drilling) and geophysical (e.g. shear wave, seismic reflection or refraction mapping, resistivity or radar) investigations to advance the predictive capabilities of hazard mapping. Also of interest are comparative studies between predictive hazard maps and actual occurrence of damaging liquefaction to assess the effectiveness of current mapping techniques.

Want to send an announcement to the SCEC community?
SCEC community announcement requests should be sent to scecinfo@usc.edu (no attachments) with the following requirements, in order to best standardize announcements and provide maximum security for recipients. These requirements also ensure that various email applications and any applied filters reach the recipient as the announcement was intended.
1) Use this style guide :
• All text must be in Helvetica, 12 pt.
• Bold, italics, and underline formatting is permitted.
• Consider the length of web links; use bit.ly or tinyurl.com to shorten them as needed.
• NO PDFs, Word Docs, images, or other attachments - all content must be in the email request itself.
2) Include a subject line.

3) Remember, send your request to scecinfo@usc.edu.

We strive to send announcements as soon as possible. In general, expect a 2-3 business day turn-around. We may also combine announcements with others, delay sending certain announcements due to current events, and even reject requests if they do not fit the needs of the SCEC community.
