Research Associate Professor Rachel Abercrombie has received 3 new research awards in the last few months to continue her work in earthquake seismology. She is collaborating with scientists and graduate students at a number of different universities and institutions. The awards, their focus, and Prof. Abercrombie’s work on them are described below:
NSF Collaborative Award
The U.S.-led international experiment project titled Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip or HOBITSS deployed an ocean bottom instrument array offshore New Zealand. The aim is to investigate the physical environment that hosts shallow slow slip and its relationship to destructive, seismic slip on the Hikurangi subduction thrust. Prof. Abercrombie is a PI with Prof. Schwartz (UCSC) and Prof. Sheehan (U Colorado) on a two-year project that will build on the initial data analysis from this experiment. Prof. Abercrombie is leading the analysis of earthquake source parameters to explore their spatial and temporal relationships with slow slip, geodetic coupling and physical properties of the plate interface.
The original deployment and early results featured in a recent EOS article titled “Investigations of Shallow Slow Slip Offshore of New Zealand.”
NSF Collaborative Award
Prof. Abercrombie and Prof. Chen (University of Oklahoma) received three years of funding to investigate earthquake stress drops, their uncertainties, and spatial and temporal changes using data from around Parkfield, California. This section of the San Andreas Fault near Parkfield, has a high rate of earthquakes, and is one of the best-instrumented sections of fault in the world.
Southern California Earthquake Center Award
For this one year award, Prof. Abercrombie is working with Prof. Shearer at UCSD to improve measurements of earthquake stress drop in Southern California.
Prof. Abercrombie also regularly visits scientists at MIT and Harvard with whom she works on a range of different projects. To learn more about her work, check out her profile page.
Earth & Environment Research Associate Professor Rachel Abercrombie and recent E&E PhD recipient Dr. Kasey Aderhold (now with IRIS) have published a new paper in Journal of Geophysical Research – Solid Earth.
The paper is titled “Seismotectonics of diffuse plate boundary: Observations off the Sumatra-Andaman trench,” and it can be downloaded here.
The work in the paper formed a chapter in Aderhold’s PhD thesis. Aderhold received her PhD in Earth Science from Boston University this past year. Abercrombie was her advisor.

Earth & Environment Research Associate Professor Rachel Abercrombie was in California this week to participate in the 2015 Southern California Earthquake Center Annual Meeting.
At the meeting Abercrombie presented a poster on the topic of “Earthquake stress drop measurements – variability and resolution.” The abstract for her poster can be found here.
Visiting Fullbright scholar Maria Kozlowska will be giving a talk titled “Effect of the coseismic static stress transfer on the seismicity in mines” this coming Thursday, March 19th, at 12:30 pm in room B31C.
Kozlowska is a visiting Fullbright scholar from Poland who has been working with Earth & Environment Research Associate Professor Rachel Abercrombie.
The article, “Stress Drops of Repeating Earthquakes on the San Andreas Fault at Parkfield,” has been published online and will be published in a later volume of the journal.
The meeting will take place from Wednesday April 30 to Friday May 2nd.
On Thursday May 1, Aderhold will be presenting a talk titled “Seismic slip distribution of large inter- and intra- plate oceanic strike-slip earthquakes.”
Then on Friday, Prof. Abercrombie will be presenting a poster titled “Improving stress drop measurements from EGF – scaling and stress release in the Darfield-Christchurch, New Zealand earthquake sequence.”
Prof. Abercrombie is also the co-author of two other presentations concerning earthquakes in Nevada and in New Zealand.

Department of Earth and Environment Research Associate Professor Rachel Abercrombie has been invited to speak today at the first of BU’s Earthquake Preparedness Exercises.
Abercrombie, a trained Earthquake Seismologist, will share her expertise with the BU Incident Command Response Team (ICRT) and other University and City officials as they run through BU’s earthquake response plan for the National Emerging Infectious Diseases Laboratories. The response plan, dubbed Operation Cerberus, will take place at the BU Biosafety Lab; similar exercises for the Charles River Campus and the Medical Campus will follow.
Although not on a plate boundary, the northeastern US still experiences earthquakes. The largest known earthquake in Massachusetts was a M6 off Cape Ann in 1755. More information about New England Seismicity can be found at Boston College’s Weston Observatory website.
