America's 'most dangerous fault'

It's a big white building on Mission Boulevard. You can't miss it; the Art Deco style is really striking. The grass is trimmed and it all looks perfectly inviting, except this is a lock-out....read about it here and see the simulation.

Websites for the Lithospheric Processes

ABAG earthquake maps and Information: ABAG, is the Association of Bay Area Governments: the regional planning and services agency for the nine-county San Francisco Bay Area. Their website has a wide range of information and maps linked to earthquakes in the Bay Area of San Francisco.

Try the Interactive (GIS) SUSCEPTIBILITY Map

· BBC British Isles: A Natural History– Links from the BBC TV series looking at the natural history of the British Isles.

· BBC Natural Disasters - From BBC Science and Nature, an overview of a range of natural disasters.

· BBC Volcano Hell From BBC Science and Nature a look at volcanic disasters and developments in volcano prediction. Includes useful video footage and weblinks.

· BGS (British Geological Survey) This section of the BGS website provides information on geological topics of general interest and items developed with schools in mind.

· Clean Slate Resources – Information for KS3 (and GCSE) students on Limestone landscapes.

· Earths Active Volcanoes Links to all the world’s active volcanoes with detailed information on each.

· Geology Toolkit (Open2.net) An off-spin from the BBC “A natural History” series with a region by region look at the geology and how it influences the landscape. Some fancy flash graphics!

· How Stuff Works: Earthquakes – Clear explanations of earthquakes; their causes, impact and a little about management.

· How Stuff Works: Volcanoes - Clear and detailed explanation of the causes of volcanic eruptions and the human relationship with volcanoes.

· How Volcanoes Work- There's enough magma, lava and pyroclastic flow to keep both novice and expert occupied for centuries here at NASA's volcanism HQ.

· IDEERS– A website by Bristol University to provide an introduction to, and demonstrations of, earthquake engineering. Includes background information on plate tectonics and an different ways of counteracting the impact of earthquakes though improvements in building design.

· IRIS Seismic monitor- Where in the world can you find earthquakes? Use the IRIS Seismic Monitor to see what's happening NOW and where, complete with recent news.

· Mountain Maker, Earth Shaker - Plenty of information about plate tectonics with some interactive graphics.

· NOAA Ocean Explorer Information about the exploration of the Ocean depths. Useful background to help your understanding of constructive plate boundaries.

· Open University Earth Sciences – This site has very good image library if you are looking for a photograph of more or less any landform.

· Peak District Landscapes Good overview of the landscapes (and people) of the Peak District relating landscape to geology and processes.

· Savage Earth Animations - If you like animations, there are some good ones here to help you understand plate tectonics, volcanoes, earthquakes, folds and faults.

· US Geological Survey – One of the largest and most comprehensive websites on the planet that will help you with most aspects of physical geography and geology. Explore the website to see the huge range of resources that it offers for all ages and all levels.

· USGS California EarthquakesAll you could possibly want to know about earthquakes on the US west coast. Check out the latest quake information.

· USGS Plate Tectonics Huge amounts of information about plate tectonics.

· Volcanic Hazards – Another fully comprehensive section of the USGS website. All you need to know about volcanoes.

· Volcano World (UND) – One of the best sources of information about volcanoes on the net.

· Volcanoes of the World- Stromboli Online: another colourful and informative volcano website with photos, video clips, etc.

· What is liquefaction? An explanation of the process that leads many buildings to collapse during an earthquake.

Plate Tectonics...animations

More magnificent animations from Wycombe High School

Click here to view an animation showing how rift valleys develop into constructive plate margins leading to the development of new oceans. The Atlantic formed in this way about 200 to 250 million years ago.


Click here to see how plate tectonics provides the explanation for continental drift and the break-up of the super-continent of Pangaea about 225 million years ago. Click here(School Members only) for an alternative animation.

Click here to see an animation showing the convectional currents in the mantle which drive surface crustal plate movements.

Click here (School Members only) to see how constructive and destructive plate margins work together in the rock cycle.

Click here to see the formation of earthquake and volcanic activity at constructive plate boundaries.

Click here to see how the magnetic field of the earth reverses and how the pattern is recorded in the igneous rocks that are formed on either side of a mid-ocean ridge at a constructive plate margin.

Click here to see how basaltic lava enters the cold sea water at ocean ridges adding fresh rock to each crustal plate.

Click here to find out how oceanic crust is destroyed at destructive plate margins. These are also locations where there are ocean trenches, fold mountain ranges, volcanic activity and earthquake activity.

Click here to see how andesitic (or acidic) magma is created in a subduction zone which feeds intrusive and extrusive volcanic features.

Click here to find out how island arcs, such as the Aleutian Islands or the Japanese islands, form where a subduction zone forms between two oceanic crustal plates.

Click here to see how collision zones occur when two continents meet at a destructive plate margin, leading to major mountain ranges such as the Himalayas. The animation is in the form of a cross-section.

Click here (School Members only) for a further animation that shows the collision zone between India and Asia from a plan (map) view.

Click here (School Members only) to see how "foliated" metamorphic rocks can be formed at collision zones as a result of the intense pressure and heat.

Click here (School Members only) to see how transform faults form, such as those in California, Turkey or offset from the Mid-Atlantic Ridge. The animation includes maps of example locations.

Click here to see the creation of rock at constructive plate boundaries, and how the destruction of rock at subduction zones helps to complete the rock cycle.

Tsunami strikes Solomon Islands

Following an earthquake 8.0 on the richter scale a tsunami has struck the Solomon Islands (off the coast of Papua New Guinea)...click here to read the BBC report.

Physical characteristics:

The quake hit at 0740 local time on Monday (2040 GMT Sunday), striking 345km (215 miles) north-west of the Solomon Islands' capital, Honiara, north-east of Australia, the US Geological Survey said, at a depth of 10km (six miles) below the surface.

Tsunami's Explained

Listen to the BBC report to hear how Australians in Queensland reacted to the news.

Brief halt for Indonesia mud flow


A massive mud flow that has displaced some 15,000 people in Indonesia's Java island halted briefly for the first time in 10 months, officials say.
