  • Natural Disaster & Urban Life

    Natural Disaster & Urban Life
    3rd EU-JAPAN Research Center International Symposium
    5 & 6 November 2012
    Faculty of Arts, Erasmushuis, room 08.16

    In recent years, natural disasters such as earthquakes, tsunami, storm surges, heavy rain and tornadoes have occurred frequently in many parts of the world, resulting in the loss of many lives and property. The scale of calamities such as earthquakes caused by tremors in the earth’s crust and movements along fault lines, or tsunami generated by earthquakes, are increasing alarmingly in pace with the advance of urbanization, leading to unprecedented complex disasters. In addition, explosive population growth and mass consumption of fossil fuels and other energy sources are indirect causes which contribute to localized ‘guerilla’ rainfalls and tornadoes striking cities and resulting instantly in the accumulated loss of social and personal capital. more

  • Two new paper on the Tohoku Tsunami, Japan, 2011

    Two new paper have recently been published on the Tohoku Tsunami that devastated the Japanese coast in March, 2011.

    In Sedimentary Geology, Chagué-Goff et al. published their results from investigations of chemical markers left by the waves in March, 2011. The authors sampled the tsunamites two, five and seven months after the event and determined the concentrations of chemical markers such as C, Ca, Cl, K, N, S, and Sr.  more

  • New paper on the Japan 2011 tsunami and implications for paleotsunami research – Updated

    Goto et al. published a short paper on the Japan 2011 tsunami and implications for paleotsunami research in Marine Geology: Goto, K., Chagué-Goff, C., Fujino, S., Goff, J., Jaffe, B., Nishimura, Y., Richmond, B., Sugawara, D., Szczuciński, W., Tappin, D.R., Witter, R.C., Yulianto, E., 2011: New insights of tsunami hazard from the 2011 Tohoku-oki event.

  • Japan – strong aftershocks continue

    A strong aftershock has rocked Japan on 11 April. USGS reported a magnitude of 6.7, while EMSC estimated M6.6. A tsunami warning has been released by the Japan Meteorological Agency for the eastern coast of Japan’s Honshu Island. UPDATE 13:06 MEST: The Tsunami warning has been cancelled. more

  • Japan earthquake aftermath – blogs and press

    The Japan earthquake and tsunami have hit Japan harder than we could have imagined. Thousands are still missing, the death toll climbs and climbs, a nuclear disaster might happen or already happened, depending on who you ask, and the economical damages are incredibly high. Not only Japan was affected, but other countries as well feel the effects. Germany, for example, shut down seven of it’s oldest nuclear power plants and there’s a big debate on earthquakes and risks. The Geoblogosphere is still discussing lessons, estimations and consequences, and so are the official media. Here are some reports and opinions you should not miss. more

  • SSA meeting: Special session on Japan, Christchurch EQs

    The Seismological Society of America has re-opened abstract submission for a special session on the Christchurch and Japan earthquakes during the Memphis conference. Deadline for new abstracts on this topic is 25 March.

    The Seismological Society of America‘s annual meeting 2011 will take place in Memphis, Tennessee from 13 – 15 April.  A special focus is set on the New Madrid earthquakes, so paleoseismologists will definitely hear some interesting sessions there. Post meeting excursions are scheduled 16 April.  For more information visit the official website.

  • Liquefaction in Tokyo Central Park

    Thanks to Alessandro I came across this incredible video of liquefaction occuring in the Tokyo Central Park during the M9.0 Japan earthquake. We can see a lot of very interesting features. First, cracks are opening, perfectly visible on the paved road and the cobble. Then we see the differential moving along those cracks, they are widening and narrowing and there’s vertical movement as well. Soon, the first ruptures appear in the meadows, despite the soft sediment there. more

  • Japan EQ & Tsunami: Environmental Effects

    The Japan M9.0 earthquake and the following tsunami are well documented by videos, photographs, sea-level measurements, seismograms etc. But how do we recognize such huge events if they happened some thousands of years ago? If there’s no historical report we would use earthquake environmental effects (EEE) for characterizing the earthquake and paleoseismicity. Let’s look what would be left from a 5000 year old earthquake and tsunami. more

  • Mw9.0 earthquake hits Japan, causes Tsunami (updated – 3)

    An earthquake with a magnitude of Mw9.0 has occured 130 km east of Honshu, Japan in a depth of ~25 km. This had been the fourth or fifth strongest earthquake to be recorded by instrumental seismology. The quake caused significant destruction to the Honshu Island and triggered a tsunami that  destroyed a number of harbours. In some places (Sendai), tsunami heights were reported to exceed 10 m. A tsunami warning has been released for wide parts of the Pacific, but in Hawaii only 1 m was observed, therefore the warnings for the US West Coast have been lowered. more
