A seismic shift in Ohio’s concerns over earthquakes. DELAWARE, Ohio — Most people likely had never heard of the Ohio Seismic Network or the state office over it, the Ohio Geological Survey.

A seismic shift in Ohio’s concerns over earthquakes

Until New Year’s Eve, when a magnitude 4.0 quake shook Youngstown. “All of a sudden, the Geological Survey has risen from a totally obscure agency to something where people know who we are,” said Michael Hansen, state seismologist. Hansen pretty much is the seismic network. The part-time state employee keeps watch over 26 earthquake detectors with an annual budget of $20,000. After the New Year’s Eve quake, his quiet office in a lab building near the city of Delaware has become the epicenter of an investigation into a string of earthquakes in the Youngstown area that’s drawn international attention. Why would such a small quake attract such a bright spotlight? Fracking. Earthquake data show a link between the earthquake and a nearby disposal well where “fracking” fluids used in oil and gas drilling sites are injected deep underground. Tectonics.

Radioactive Decay: The Source of Earth's Internal Heat

What melts iron in the outer core and enables the Earth's magnetic field? Heat. Geologists have used temperature measurements from more than 20,000 boreholes around the world to estimate that some 44 terawatts (44 trillion watts) of heat continually flow from Earth's interior into space. Where does it come from? The Source of Earth's Heat Radioactive decay of uranium, thorium, and potassium in Earth's crust and mantle is a principal source, and in 2005 scientists in the KamLAND collaboration, based in Japan, first showed that there was a way to measure the contribution directly. "As a detector of geoneutrinos, KamLAND has distinct advantages," says Stuart Freedman of the U.S. KamLAND scientists have now published new figures for heat energy from radioactive decay in the journal Nature Geoscience.

15 Awesome Chemistry Experiments. You don’t need to watch Breaking Bad to know that chemistry is pretty awesome.

15 Awesome Chemistry Experiments

Below we explore our favorite 15 chemistry GIFs. Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on.
