Typhoon Haiyan was among the strongest storms ever recorded and likely the strongest one to make landfall in historical times. This mega storm hit the Philippines with windspeeds of more than 300 km/h. It caused thousands of fatalities, widespread flooding and devastation especially in its direct path. NASA’s Terra satellite is equipped with the ASTER sensor. This sensor is perfect for producing false color images of land cover and vegetation. In this image series it becomes clear that typhoon Haiyan destroyed a significant part of the vegetation around Tacloban.
Dave Petley has a good article on the storm surge and some earthquake environmental effects over at his landslide blog.
Birth of a new island
In Japan, an undersea volcanic eruption has created a new island, almost on time with Surtsey’s 50th birthday:
A poltical map of Pangea
This map shows how Pangea would look like with our recent political maps, more or less, approximately.
A geological 3D model of Brandenburg, Germany
Currently we observe that geospatial data in Germany are being released and become freely accessible – open data! It’s a slow process, but a good and necessary one. This is great for science, for teaching and for the industry. Digital Geography has some nice examples of the new 3D geological model of the German state of Brandenburg (in German).
The dilemma of retrofitting
Nice image gallery of San Andreas and Calaveras Faults
California is full of faults, and not all of them do cause major earthquakes every now and then. Some do also creep, which means they are moving aseismically – slowly, but unstoppable. Geotripper Garry Hayes has a great image gallery of the effects of creep at the San Andreas and Calaveras Faults.
A quarry blast-triggered earthquake?
On 4 November the earth was trembling
almost in the centre of Chicago in the Chicago area. The tremor had magnitude mb3.2 and was widely felt, but the USGS soon categorized the event as a quarry blast. There are some hints that the blast, however, might have triggered a tectonic event…
3rd Int’l Landscape Archaeological Conference 2014
- Landscape Archaeology and Contemporary Society
- Integrated approaches in Landscape Archaeology
- Mediterranean Landscape Archaeology
- Social Dimensions in Landscape Archaeology
- Digital Landscape Archaeology
Why I do post this here? Because landscape archaeology can be pretty closely related to earthquake environmental effects (EEEs) and they have a session on “Disasters that change landscapes: causes, evolution afterwards and researching disaster-struck landscapes“.
A lot of M4.0 earthquake in Europe last week
During the last week, several earthquakes with magnitude of 4.0 and above were felt in Europe. Seismic shaking not only concentrated on the usual suspects (Greece, Turkey), but also surprised people in France, Croatia, Iceland, Serbia, Albania, and Romania.
Plus, there was M7.7 in the Scotia Sea! Beautiful after shock sequence…
Have a nice weekend!
