Installing GPS in Myanmar

Back in February, members of our group went to Bangladesh to install equipment along the Western side of our large geophysical transect across the IndoBurman subduction zone (red triangles on the map). This is the world’s only subduction zone that is entirely on land. Because of this fact and because of its slow rate of motion, it is often neglected or thought to not be active. However, we believe it is active and that there is a significant earthquake hazard in this densely populated region. Thus, we developed this large project to study it using many geophysical and geologic tools.

We are now in the next stage of installing equipment. I am now in Myanmar to install five GPS stations along the Eastern side of the transect (white circles). Once again, Keith Williams, an engineer with UNAVCO is with me to provide support. The seismic team, this time from the University of Missouri and Louisiana State University will arrive in about a week to start their work installing seismometers at the green triangles. Keith and I will start installing GPS stations going from West to East along the transect. The seismic team will go East to West and we will cross paths and meet them later in the trip.

We have arrived in the Myanmar capital, Nay Pyi Taw, on the last day of a major Buddhist holiday, the Thadingyut festival. While the offices of our

partners, the Department of Meteorology and Hydrology (DMH), are closed, stores are still open so we shopped for a few things, rested from the long flights and visited the Uppatasanti Pagoda. It is a copy of the famous pagoda in the capital, Yangon, but a foot shorter out of respect for the original.

The following day, we were able to work with our partners at DMH on preparations for the fieldwork. We settled the bills for the things they bought for our work, checked our shipped equipment, got supplies, such as a sledge hammer, pieces to make a post pounder, locks and chains to secure the

GPS, SIM cards for the modems in the GPSs, and a ladder. Along the way we drove on one of the amazingly wide roads in Nay Pyi Taw. There are 10 lanes in each direction, but we never saw more than about a half dozen cars in front of us. The new capital, only opened in 2006, is built on a huge scale and very spread out. As the center of the government, it now has over 900,000 people, but is not yet a vibrant city.

After shopping, we sent the 12 foot steel rods for building the monuments, the batteries and the ladder off to be transported to our basecamp by bus. Today, we finished our preparations, rewiring the GPS and welding the post

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
