Japan-UNESCO/UNU Symposium on The Great East Japan Tsunami on 11 March 2011 and Tsunami Warning Systems: Policy Perspectives
The Great East Japan Earthquake and Tsunami on 11 March 2011 caused nearly 20,000 people to lose their lives.
Since the event many national and international post-tsunami field surveys have been carried out. Performance analyses of tsunami early warning systems in place at the time of this event have also been done. Based on these surveys and performance analyses the symposium will offer a number of invited high level perspectives from decision makers and scientists and address topics including:
- Event facts and analysis
- Tsunami Warning Systems, Tsunami preparedness and event experiences
- What has been learned from this event and policy implications.
The symposium will be opened by Ms Irina Bokova, Director General of UNESCO.
Venue and Date
- United Nations University (Jingumae, Shibuya-ku, Tokyo, Japan)
- 16-17 February 2012

TALLER SOBRE SISTEMA DE ALERTA TEMPRANA NACIONAL ANTE TSUNAMI Y SISTEMAS OPERACIONALES ESTÁNDAR, PERU
Taller sobre Sistemas de Alerta Temprana de Tsunami en el Peru
La mayoría de los más grandes y devastadores tsunami han ocurrido en el Oceano Pacífico y sus mares marginales. La razón es que el Pacífico cubre más de un tercio de la superficie del planeta y está rodeado por una serie de cordilleras, fosas océanicas y arcos de islas llamadas “anillo de fuego”, donde se genera la mayoría de los terremotos. En consecuencia, la costa pacífica de Sudamérica es una de las zonas más propensas a un tsunami. Sin embargo, como no ocurren con frecuencia, muchas veces las comunidades que viven en estas zonas costeras subestiman o ignoran el riesgo. Los tsunami son una fuerza altamente destructiva, y cuando ocurren,la pérdida de vidas, el número de personas heridas y el daño de infraestructura pueden ser extremadamente altos, como se demostró en el tsunami en el Océano Indico en 2004, el tsunami de Chile de 2010 y el tsunami de Japón de 2011.
Tomando en cuenta lo anterior y a fin de apoyar a los gobiernos en la reducción de vulnerabilidad de zonas costeras a la presencia de tsunami, la Oficina Regional de Educación para América Latina y el Caribe OREALC/UNESCO Santiago, en asociación con la Comisión Oceanográfica Intergubernamental de la UNESCO (COI), la Comisión Permanente del Pacifico Surc (CPPS), y las oficinas de UNESCO de Lima y Quito, ejecuta el proyecto “Fortalecimiento del Sistema Regional de Alerta ante tsunami en Chile, Colombia, Ecuador y Perú” que se implementa en el marco del Séptimo Plan de Acción para Sudamérica del Programa de Preparación para Desastres (DIPECHO VII) de la Dirección General de Ayuda Humanitaria de la Comisión Europea (DG-ECHO).
El objetivo del proyecto es fortalecer el sistema sub-regional de alerta temprana, para lo cual considera necesario fortalecer primero los del nivel nacional. Para ello, se vale de la coordinación con los institutos sismológicos, oceanográficos, ministerios de educación y oficinas de preparación y atención de desastres de cada país.
En esta ocasión, el taller propuesto se apoya además de las iniciativas locales en prevención de desastres por tsunami impulsadas por el PNUD y la ong PREDES, ambas también enmarcadas dentro del DIPECHO VII.

Tectonics: Unexpected Andean earthquakes
- Nature Geoscience 4, 357–358 (2011) doi:10.1038/ngeo1167
- Published online
- Great earthquakes along the western, subduction zone boundary of the Andes Mountains in South America are expected. Measurements of surface motion along the eastern boundary highlight the potential for equally large earthquakes in the east.

Orogenic-wedge deformation and potential for great earthquakes in the central Andean backarc

Subduction of the Nazca plate beneath South America has driven the growth of the Andes Mountains. Subduction has routinely generated earthquakes larger than magnitude 8.0 along the western margin of the mountain belt1, but the potential size of less frequent earthquakes in the eastern, backarc margin is unknown. Continued support of the high Andean Plateau at the centre of the Andes can be explained only if deformation of the backarc margin is ongoing2, 3, 4. Here we present GPS data that record surface motions in the Subandean ranges that are part of the backarc margin. We find that the velocity of surface movement decreases sharply from west to east across the Subandean ranges. We suggest that a subhorizontal fault underlying the ranges slips freely at depth in the west, but is locked for up to 100 km in shallower sections further east. Analysis of fault scarps formed where the subhorizontal fault intersects the surface indicates that the fault has generated repeated large earthquakes. We suggest that rupture of the entire locked section of the fault could generate an earthquake of magnitude 8.7–8.9. We attribute the large seismic potential to the unusual width of the Subandean ranges, and suggest that deformation of the Subandean ranges, at a rate unmatched by erosion, causes the mountain range to widen.
