Hiron Point in Sundarban
We traveled by boat to the south part of the Sundarbans near the Indian Ocean to install a GPS at Hiron Point, this isolated facility also hosts a tide gauge recording long-term water level changes due to rising sea level and land subsidence. Our GPS will help distinguish how much of each there is in…

Polder 32
Polder 32 is one of the many inland islands in Bangladesh that was enclosed by an embankment to protect it from flooding. When that embankment failed during Cyclone Aila in 2009, the island was flooded for almost 2 years. Subsidence of the ground inside the embankment with no sedimentation to compensate made it worse.

Khepupara to Kokilmoni
Leaving Dhaka, we spend an entire day getting to Khepupara in southern Bangladesh. Then we spent a long morning installing a GPS to monitor subsidence of the delta before heading back on the road again.

To Comilla and Back
I’ve just arrived back in Bangladesh with an engineer to install 6 new GPS stations to add to our studies of earthquake hazards and land subsidence. Our first stop was Comilla University, the westernmost exposed fold of the collision between the Ganges-Bramaputra Delta and the Sumatra-Andaman-Burma plat boundary.

Rivers and the Road
We spent a day on the islands (chars) in the Brahmaputra River seeing the geology and talking to the residents. Then after an evening of feasting and dancing in our new Saris and lungis, we hit the road for the trip to the Sundarbans.

Jumping Ship
As we finally reached our prime target area, it was time for me to leave the ship and return home. Despite initial struggles on navigating the Brahmaputra River, we have worked together with the ship’s crew and pilots for a successful method. And now as I leave with many new friends, the best data is…

Cruising up the Brahmaputra
Rejoining the ship, we sailed up the Padma and Jamuna (Brahmaputra) Rivers. Hurrying to our primary area with the help of pilots, we finally collected good seismic data.
