Tenth Planet Discovered
Astronomers at the Palomar Observatory have discovered what they believe is the tenth planet. Located in the Kuiper Belt, nearly 100 astronomical units from the sun, it is the furthest known object in our solar system and has a size larger than Pluto.

Interactive Topographic Map of Mars
Astronomy Picture of the Day has posted an interactive topographic map of Mars. There you can explore volcanoes of the Tharsis province (much larger than any mountains on Earth), Valles Marineris (a canyon much longer and deeper than Earth's Grand Canyon) and Hellas Planitia (a basin over 2000 kilometers wide that was likely created by a collision with an asteroid).

What Does an Earthquake Sound Like?
What does an earthquake sound like? Researchers at Columbia University's Lamont-Doherty Earth Observatory have prepared a sound file for the December 26th, 2004 earthquake - the earthquake that generated the devastating tsunami. Sound recordings from the International Monitoring System of the Comprehensive Nuclear Test Ban Treaty were made avaiable to the Lamont-Doherty researchers and they have posted a refined sound file that you can hear on an MP3 player. Visit their website to hear the Earthquake Sounds. Labels: Earthquakes

Images of the the Apollo Landing sites.
Google maps has posted images of the lunar landing sites - Apollo 11, Apollo 12, Apollo 14, Apollo 15, Apollo 16 and Apollo 17. You can zoom and pan over a limited portion of the moon surrounding these sites and get interesting views of craters and other features. You can also click on the landing sites to see information about the mission and the astronauts.

Free Data and Maps for Science and Geography
We just found out about geodata.gov - a website that provides free access to lots of government data and maps. There you can find information about: administrative and political boundaries, agriculture and farming, soil resources, water resources, atmospheric and climatic data, biology and ecology data, geological and geophysical data, business and economic data, cadastral data, cultural, social and demographic data, and information on archeology and anthropology. Topics include: amphibians and reptiles, bird conservation, coastal and inland waters, ecosystems, fisheries and aquatics, forestry, invasive species, mammals, museum collections, pollinators, vegetation, wildlife disease, built environment, historical features, family and social services, law enforcement, education, elevation and derived products, conservation, land cover, meteorology, natural resources, environmental risk, watersheds, human health and disease, imagery and base maps, orthoimagery, inland water resources, drainage network, major water databases, locations and geodetic networks, oceans and estuaries, transportation networks, utilities and communication.

Tsunami Earthquake Animation
Researchers at Delft University of Technology have created an animation that visually displays several elements of motion for the December 26, 2004 Earthquake. This earthquake occurred over a ten minute time interval. The animation shows the following.... 1) the progression of fault rupture across several hundred kilometers of seafloor, 2) propagation of the seismic surface waves, and 3) displacement of a few dozen GPS monitoring stations show large scale plate motions over the ten minute duration of the earthquake. This animation is worth watching and will make you realize that earthquake motion is not confined to a single point at the focus. View the Tsunami Earthquake Animation and more interesting graphics at the Delft University of Technology website. Available on geology.com are two articles: What Causes a Tsunami? and Indonesia Tsunami Maps. Labels: Earthquakes, Tsunamis

Alaska Dinosaur Tracks
Susi Tomsich, a University of Alaska Fairbanks undergraduate student found what is thought to be a track from a bird-like dinosaur in Alaska's Denali National Park. The dinosaur track was found in rocks of the Cantwell Formation that are thought to be about 70 million years old. This is the first evidence of dinosaurs found in Denali National Park and Preserve.

Deep Sea Drilling to Earth's Mantle
The Integrated Ocean Drilling Program (IODP) is preparing Chikyu, a deep sea drilling vessel, capable of penetrating the oceanic crust to levels deeper than any previous drilling ship or platform. Capable of handling 12,000 meters of drill string and 4,000 meters of riser Chikyu will be well equipped for sampling deep sea sediment, exploring the oceanic crust, and a possible attempt to be the first successful penetration of Earth's mantle. Anyone interested in deep sea drilling should visit the IODP website. They have lots of interesting facts about deep sea drilling, IODP expeditions, and a scientific report and prospectus collection which includes information on Juan de Fuca Hydrogeology, Arctic Coring Expedition, North Atlantic Climate, Ocean Core Complex Formation, Modern Carbonate Mounds: Porcupine Drilling, Gulf of Mexico Hydrogeology, Superfast Spreading Rate Crust, Tahiti Sea Level Provisional Prospectus and Cascadia Margin Gas Hydrates. Perhaps the most interesting and educational resources on the site are the videos on Deep Sea Drilling and Rotary Drilling. IODP is also sponsor of the Teachers-at-Sea Programs.

Flood Mapping on the FEMA Website
The Federal Emergency Management Agency has been upgrading the FIRMs (Flood Insurance Rate Maps) on their interactive website. Now you can go there, type in your address and for most parts of the USA get a rough idea of the flood hazard. Also on the FEMA website are tutorials on how to read a flood map and other useful information. View flood insurance rate maps and learn more about them at FEMA's Flood Mapping website. While you are there you can use the same interface to view hurricane track maps, tornado incidence maps, and earthquake epicenter maps.  Labels: Floods-Flooding, Maps

Indian Ocean Tsunami Warning System Established
UNESCO announced the establishment of a tsunami warning system for the Indian Ocean. This is a multi-country cooperation to share expertise, data, equipment and communications to reduce the tsunami threat in the Indian Ocean. Work on the system has already begun and it is expected to be fully operational by July 2006. It will consist of enhanced seismograph networks, networks of real-time sea-level gauges and deep-sea ocean pressure sensors, along with national tsunami warning centers linked to national disaster management systems. Also announced were similar programs started for the Caribbean, the North-East Atlantic and the Mediterranean. Read more at the UNESCO Tsunami Website. Also posted at the UNESCO site are summaries of what individual countries have done to reduce the impact of tsunamis, including Australia, Indonesia, India, Iran, Japan, Korea, Kenya, Mauritius, Thailand, South Africa, Norway, Italy, Canada, United States, Germany, France, and Belgium. For more information about tsunamis visit our What Causes a Tsunami? and Tsunami Maps pages. Labels: Tsunamis

Record Flooding Continues in China
Heavy summer rains in eastern and southern China have resulted in widespread flooding and deadly mudslides. The image below shows cumulative rainfall for June 13 through June 28, 2005. Some areas of China have received up to 400 mm (16 inches) of rain during this two week period. Visit the Earth Observatory website to learn more about this image and see other information about flooding in China.  Labels: Floods-Flooding
