109 is a visual arts and science collaborative project which aims to explore and reflect upon the diversity of elements that comprise matter in as unique and innovative manner as possible. 109 aims to produce a new and vibrant visual assessment of the startling diversity of material that constitutes the world in which we live, not simply by rendering images of the respective elements but also by investigating the manner in which they affect our daily lives in largely unseen and often unexpected ways. The site contains an interactive periodic table. Clicking on any element in the table brings up a web page with practical, historical, and physical information and animations relating to that element. The site also has a section entitled Periodic Landscapes which contains computer generated landscape views and models based on various patterns and relationships within the periodic table. The site also includes a brief history of the periodic table, free e-postcards, and more. (less)

This map shows estimated Modified Mercalli Intensity (MMI) values for the City of San Francisco and the eight counties of the Greater Bay Area, in a scenario based on the 1906 earthquake along the San Andreas fault. The 430 kilometers of fault rupture included several segments during one massive earthquake. Links are supplied to more detailed maps of the cities of Rohnert Park, Pittsburg, Antioch, San Francisco, and Palo Alto. (less)

This lesson uses interactive diagrams of ground shaking from the 1906 San Francisco Earthquake to teach students about the mechanics involved in the rupture of a fault and the propagation of seismic waves as an earthquake progresses. They will understand that earthquakes begin at a point; that a long section of a fault can rupture during an earthquake; that the earth shakes in all different directions and modes; and that the intensity of shaking depends on the amount of energy released by the earthquake, distance from the fault, and the type of soil or rock beneath the surface. Links are provided to additional lesson plans and information, and to the complete movie of shaking intensity from which the diagrams were made. (less)

This web page covers the progress of the early 1960 Kapoho eruption of Kilauea Volcano, Hawaii, and the damage it caused. The eruption caused havoc in lower Puna, an idyllic rural paradise until the lava fountains and flows covered farm land and villages including Kapoho Village and parts of Koa`e Village. During this time, the volcano's summit deflated and eventually collapsed. This page is part of a web series on major Kilauea eruptions. The user can view a series of maps for mid- to late January 1960, showing lava coverage, faults, and lava barriers. A memorial poem for Kapoho village is included. Other links include a photo gallery of volcanoes, and a resource on how volcanoes work. (less)

This web page describes the lahars that swept down the Drift River Valley during the 1989-90 eruption of Redoubt Volcano, Alaska, and the testing of a new experimental detection and warning system designed to track lahars and debris flows and to give warning to people downstream. In this case, an oil-storage facility in the Cook Inlet area was at risk. The seismometers used (acoustic-flow monitors) were sensitive to ground vibration at relatively high frequencies. On April 6, 1990 the system did detect and track lahars moving down a valley in real time. The amplitude and ground velocity data are diagrammed. (less)

El Nino, a periodic warming of the Eastern Pacific Ocean, is among Earths most powerful phenomena. Satellite, ship, and buoy observations show the 1997-98 event as the strongest on record. Visualizing how sea-surface height, sea-surface temperature, and sea-surface winds differ from normal conditions reveals the events magnitude. (less)

TOMS provides dramatic visual evidence of the annual growth and decay of the Antarctic ozone hole. The ozone losses over Antarctica result from reactions with the products of man-made chlorine and bromine compounds. Because of the tilt of the Earths axis, continuous darkness falls at the South Pole from March 21 to September 21. The dark region in the middle of the July 1 total ozone picture is polar night, where TOMS cannot make measurements. Ozone losses are in blue. Beginning in August, returning sunlight reaches the edges of Antarctica providing chlorine and bromine compounds with energy to rapidly destroy ozone. By mid September, the ozone loss peaks, creating an ozone hole over Antarctic. For more information see www.gsfc.nasa.gov-topstory-2003-1208toms.html (less)

A relatively warm Antarctic winter in 2004 kept the thinning of the protective ozone layer over Antarctica, known as the ozone hole, slightly smaller than in 2003. Each year the hole expands over Antarctica, sometimes reaching populated areas of South America and exposing them to ultraviolet rays normally absorbed by ozone. Scientists have new tools to study this annual phenomenon, and the human-produced compounds that contribute to ozone breakdown are decreasing. On September 22, 2004, ozone thinning over Antarctica reached its maximum extent for the year at 24.2 million square kilometers (9.4 million square miles). The largest maximum area on record was 29.2 million square kilometers, in 2000. On October 5, 2004, the ozone layer reached a low value of 99 Dobson Units. (less)
