Using newly refined analysis methods, scientists have discovered that a North Korean nuclear bomb test last fall set off aftershocks over a period of eight months on a previously unmapped earthquake fault nearby.

In a new study, researchers report that their physics-based model of California earthquake hazards replicated estimates from the state’s leading statistical model.

In a new study, researchers show that machine learning algorithms can pick out different types of earthquakes from three years of data at Geysers in California. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below.

In the final push, we split into multiple teams, and caught up and completed all the seismometer installations on time.

Helping Jim’s team, I assisted in installing stations and scouting locations. While some stations go quickly, others took multiple trips to find a good site. Time is growing short for getting all the seismometer installations done on time.

As we finished scouting and installing the GPS stations, we started to assist the seismology team in getting permission to install there instruments in Tea Estates.

We drove through the hills of Sylhet passed rice fields and tea plantations, and through woods looking for appropriate spots to install our GPS systems.

Up ahead was a school, perfect for a GPS installation. Schools proved to be the best sites in the hills, which we covered in either tea plantations or woods.

From our base in Srimongal, now came the challenging work of finding appropriate locations to install the GPS. It requires a combination of the right tectonic setting and reinforced concrete buildings.

I am back in Bangladesh to start deployment of seismometers and GPS for a large new project that crosses 3 countries: Bangladesh, India and Myanmar.
