500 Natural sciences and mathematics
Discovery channel on-line Earth Alert (Discovery Communications Inc. ) - daily news reports on a wide range of natural hazards and events, including earthquakes, volcanoes, weather, avalanches, animals etc.
Astronomy and allied sciences
J-Pass 2,0 (NASA) - this is a programme which runs within your browser and plots a sky map showing the path of any satellite(man-made) directly overhead. After setting up the programme (automatic) all you have to do is put in values for latitude and longitude, the time of day and then choose a satellite. It will also show the positions of the International Space Station, MIR and the (US) shuttle when applicable. Very useful for a realistic overview of all the satellites in orbit, as well as to know what you are actually seeing when you look up at night.
Today┤s space weather- from the Space Environment Center (NOAA). Realtime data: H-alpha solar images, X-ray flux and other electromagnetic parameters measured on satellites in earth orbit. Presented in colourful graphical format
Auroral Activity Estimates(Space Environment Center (SEC) of NOAA) - maps of auroral activity ("northern lights") based on measurements from satellites. The satellites measure the power flux carried by the protons and electrons that produce aurora in the atmosphere.
Mars daily weather report (almost realtime!) NOT OPERATIONAL until spring 1998.
Mars Global Surveyor (JPL/NASA) - recent telemetry. Information on the spacecraft┤s systems at one-minute updates, (when it is being tracked.). Look especially at the science payload deck.
Mars Pathfinder - Live Video and Audio (NASA Select TV/Vosaic Inc.) - streamed TV & audio from a number of mirrors. Operational July 1997 - ?? No plugin necessary but 28,800 bps modem is and your system provider may need to contact support.
Mars today (Howard Houben) - a poster produced daily by the Center for Mars Exploration at NASA's Ames Research Center. The updated poster depicts current conditions on Mars and its relationship to Earth in six panels.
- 523.6 Comets
NASA's Near-Live Comet Watching System (NASA) -Images of Comet Hale-Bopp from amateur and professional astronomers, posted on the 'net in near-real time.
540 Chemistry and allied sciences
- 551.21 Volcanoes
Earth's Active Volcanoes (MTU) - interactive map of world┤s active volcanoes, a few of which are usually erupting or going to at any time.
Etna (Italy) - (Istituto Internazionale di Vulcanologia ) -video camera on this currently active volcano.
Global Volcanism Program: Preliminary Notices of Volcanic Activity (Smithsonian Institute) gives up to date reports (unconfirmed) of very recent and on-going eruptions - listing is automatically updated every 90 minutes; notices older than eight weeks are automatically removed.
Mount Fuji (Japan) - active central volcano, Japan. It might erupt!
Mount Fuji (2)- alternate high tech. site. Control of camera possible - zoom, pan etc.
Popocatepetl, Mexico (CENAPRED)- realtime netcam view.
Popocatepetl (Mexico) - daily reports on the volcano
Ruapehu (NZ) (Cyber Corp Limited - cam recorder image updated when there is activity at this rather unpredictable volcano.
Sakurajima Volcano, Japan (Jun Ushirogata, VRC) - realtime view of a classic active strato volcano. The text is in Japanese.
Science Alert Bulletins for Ruapehu and White Island (Inst. Geological & Nuclear Sciences Limited) - predictions from Wairakei Research Centre of IGNS.
Stromboli (Italy) - (Istituto Internazionale di Vulcanologia ) -video camera on this well known volcano.
Volcano Research Center (VRC-ERI, Univ. Tokyo) - ongoing and recent eruptions in Japan.
- 551.22 Earthquakes
Helicorder- video image of seismograph at UNRSL, Nevada.
Mount St. Helens Seismicity Information (University of Washington Geophysics Program) - list and map of seiamic events in the Mt. St. Helens area practically in real time. Worth looking at as an example of volcanic - related seismic activity and you may eventually see the seismic patterns leading up to an eruption! (note to Icelandic students: good comparison here to Krafla events)
Seismic Monitor (IRIS) - a VERY high-tech colour world map, updated every 30 minutes, showing earthquake distribution, age etc in various colours. Earthquakes that have occurred within the last 24 hours are shown with red circles. The circles fade through orange to yellow within 15 days. After 15 days, the circles are replaced by light purple dots that remain on the map for five years. The map is also interactive, giving various information when epicenters are selected. Zoom facility.
Seismo cam- video image of seismograph recorder at NBC-4 Los Angeles, Ca.
Tsunami - WEST COAST & ALASKA TSUNAMI WARNING CENTER - near realtime warnings and information on possible tsunami, with related earthquake information. Much additional material on the subject.
USGS-National Earthquake Information Center- near realtime global earthquake information.
Veurstofa ═slands Jarelissvi (Meteorological Office - Geophysics Dept.)
- gives maps of selected regions in Iceland showing epicentres for the last 48 hours. Select from the following:═sland, Hengill, Reykjanesskagi, Suurland. Mřrdalsj÷kull.
- 551.3 Surface and exogenous processes and their agents
- 551.4 Geomorphology and hydrosphere
"Global montage" - Integrated Earth Information Server (IEIS) - a colour map of the world created every 6 hours, showing distribution and temperature of the earth┤s ice, sea, land and cloud.
- 551.5 Meteorology
Tromso weather- realtime weather info. from Tromso University, Norway.
Earth Watch- realtime 3-D images of present weather over USA constructed from satellite and radar images.
Veur og fŠr ß vegum ( Information on road conditions and weather) (Vegager ═slands - the Icelandic Roads Authority) - gives almost realtime data on temp. humidity etc., from various places in the country, including highland areas.
