    The article link goes to the article with the comparative images from space. The image below is the full-size picture at quarter-size; click for full-size. At some point in the future I'm sure there will be an expedition to get pictures on the ground, but this is a pretty inhospitable location. The new lava flow is the very dark area spreading northward from the white volcanic peak (Dalaffilla). The article has a labeled image showing where the apparent eruptive fissure was located.

    The Red Sea is parting again, but this time Moses doesn’t have a hand in it. Satellite images show that the Arabian tectonic plate and the African plate are moving away from each other, stretching the Earth's crust and widening the southern end of the Red Sea, scientists reported in this week's issue of journal Nature. Last September, a series of earthquakes started splitting the planet's surface along a 37-mile section of the East African Rift in Afar, Ethiopia. Using the images gathered by the European Space Agency's Envisat radar satellite, researchers looked at satellite data before and after these...

    Sumatra quake pushed Phuket 32cm southwest and moved Bangkok: expertPhuket shifted 32 centimetres to the south-west and Bangkok moved nine centimetres as a result of the Sumatra earthquake that caused the devastating tsunami two months ago, a Chulalongkorn University lecturer said yesterday. Dr Itthi Trisirisattayawong, head of the Faculty of Engineering’s Survey Engineering Department, said the positions of Phuket and Bangkok were measured and compared with data recorded in October. He said the measurements were carried out using GPS (global positioning system) receivers installed at Phuket’s Promthep Cape and at the Faculty of Engineering. The land position measurements were carried...

    China and India both know about underground UFO base in the Himalayan border area deep into the tectonic platesKongka La is the low ridge pass in the Himalayas (the blue oval in the map). It is in the disputed India-China border area in Ladakh. In the map the red zone is the disputed area still under Chinese control in the Aksai Chin area. The Chinese held northeastern part is known as Aksai Chin and Indian South West is known as Ladakh. This was where Indian and Chinese army fought major war in 1962. The area is one of the least...

    But Indonesia failed to heed him; Utah isn't listening either, he says PROVO — Brigham Young University geology professor Ron Harris has had trouble sleeping since the earthquake he predicted seven years ago killed an estimated 150,000 people along the rim of the Indian Ocean on Dec. 26. Research by Harris indicated an earthquake with a magnitude of at least 8.0 was due in the ocean west of Sumatra and would cause a devastating tsunami. He published the research in an Indonesian journal and pleaded with the government there to prepare, but little was done. "It might not have made...

    The NASA Earth Observatory has a facinating look at the mechanics of what happened in this horrific disaster which took place in SE Asia. The PDF shows why it is critical that a tsunami warning system is emplaced in the Indian ocean such as that which is in the Pacific. The area has five converging tectonic plates, the Eurasia plate, Australian plate, India plate, Sunda plate and the Burma microplate. The India Plate and the Burma Microplate meet along the Sunda trench to the west of Sumatra. On the 26th, the India Plate subducted, i.e. slipped underneath, the Burma Plate,...
