Earthquake Geology of the 16 April, 2016, Kumamoto Earthquake – report by Koji Okumura

On 16 April an earthquake of magnitude Mw7.0 hit the district of Kumamoto, Kyushu Island, Japan. The quake was preceeded by a Mw6.1 foreshock one day before. It occurred on the ENE striking, right lateral Futagawa-Hinagu fault zone. Our colleague Koji Okumura from Hiroshima University has prepared a short report on this surface-rupturing event. Download the report here (PDF, 612 kb). The report will be continuously revised and corrected, so check for regular updates. Thanks Koji for providing this summary!

IGCP Project 639 “Sea-level changes: From minutes to millenia” – First Meeting Announcement

The IGCP project 639 deals with sea-level changes, coastal earthquakes, and inundation by storms and tsunami: “Sea-level changes: From minutes to millenia”. The first meeting in Oman will take place from 9-14 November 2016 and will cover all science under the IGCP project 639 banner. Make sure to put this on your agenda if you’re interested.

Further details will be forthcoming in the second announcement in the next month. The abstract submission deadline will likely be 1 August, 2016.

New papers on paleoseismology, tsunami, and active tectonics (Apr 2016)

This is the April edition of my paper round-up. Today I recommend papers on high-resolution topography data, fault mechanics, earthquake environmental/archaeological effects (liquefaction, rotated objects, landslides), Quaternary dating, a fault database for Asia, and tectonics of New Zealand and Martinique. Enjoy! Continue reading “New papers on paleoseismology, tsunami, and active tectonics (Apr 2016)”

Richard Styron’s Python tool for calculating fault slip rates from offset marker data

Richard Styron has published several interesting tools for fault/stress analysis and other geoscience problems, see his website here: http://rocksandwater.net/. The latest Python tool he is sharing with us is for calculating fault slip rates from offset topography data – great stuff for paleoseismologists! He announced this a few days ago and allowed me to spread the news. Check it out and let him know what you think!

Hi all,

Last year I built a tool to calculate fault slip rates from offset marker data (age and offset distance of features cut by faults).  Although I will be publishing a paper using it eventually, I’d like to spread the word about it now and just get it out to the community.  The Slip Rate Calculator can be found here:  https://github.com/cossatot/slip_rate_calculator, with more documentation.
