2017 in Review

Dear EOS Community,

As the year comes to a close, I’d like to thank you for your continued interest and support in the research, initiatives and programs being conducted here at the Earth Observatory. Over the past year, your increased engagement has helped us to better understand your interests in geohazard research and provide content to meet them. From publications to awards and new blog series, here is a look back on a few highlights from 2017.

Malay Thai Peninsula

The sea-level database (81 index points and 12 limiting data) from the Malay-Thai Peninsula reveal an upward trend of Holocene relative sea level from a minimum of -22 m at 9.7 – 9.2 ka to a

Time scales of volcanic unrest and dynamics of magma ascent

Petrological studies can inform of the processes and time scales of magma movement and ascent, and thus allow associating them with monitoring unrest signals, and thus better mitigate volcano hazar

Earthquake Seismology of Myanmar

We propose to install 30 broadband seismometers to cover the seismic gap on the Sagaing fault and the neighbouring region, which is one of the most populated areas in Myanmar. The seismic data will be used to better understand the seismotectonic setting in the region. The proposed works include waveform modelling for earthquake focal mechanism and crustal and slab velocity structure, and determining micro-seismicity location, locking depth and the slip rate on the fault. These will be key for seismic hazard estimation and preparedness in Myanmar.
