- A ~500-percent increase in Earth’s volcanic activity between 1875 and 1993 (Mandeville 2000)
- 9 out of the 21 most severe earthquakes from 856-1999 AD occurred in the 20th century (Russian National Earthquake Information
- A 230-percent increase in the strength of the Sun’s magnetic field since 1901 (Lockwood, 1998)
- Recent magnetic pole shifts of Uranus and Neptune, as Voyager 2 observed their magnetic axes being significantly offset from their
rotational axes (Dmitriev 1997)
- 200-percent increase in the intensity of Jupiter’s magnetic field from 1992-97 (Dmitriev 1997)
- Significant melting of Martian polar icecaps in just one year, clearly seen in satellite photography (NASA 2001)
will be seeing increase in this small quakes until we have added "couple zeroes" to end of the number of seismographs in the world.
A look at the number of volcanoes active per year, over the last few centuries, shows a dramatic increase, but one that is closely related to
increases in the world's human population and communication. We believe that this represents an increased reporting of eruptions, rather than
increased frequency of global volcanism: more observers, in wider geographic distribution, with better communication, and broader publication. The
past 200 years (see plot below) show this generally increasing trend along with some major "peaks and valleys" which suggest global pulsations. A
closer look at the two largest valleys, however, shows that they coincide with the two World Wars, when people (including editors) were preoccupied
with other things. Many more eruptions were probably witnessed during those times, but reports do not survive in the scientific literature.
If these apparent drops in global volcanism are caused by decreased human attention to volcanoes, then it is reasonable to expect that increased
attention after major, newsworthy eruptions should result in higher-than-average numbers of volcanoes being reported in the historical literature. The
1902 disasters at Mont Pelee, St. Vincent, and Santa Maria (see 1902 arrow) were highly newsworthy events. They represent a genuine pulse in Caribbean
volcanism, but we believe that the higher numbers in following years (and following Krakatau in 1883) result from increased human interest in
volcanism. People reported events that they might not otherwise have reported and editors were more likely to print those reports.
Additional strong evidence that the historical increase in global volcanism is more apparent than real comes from the lower plot below. Here only the
larger eruptions (generating at least 0.1 km3 of tephra, the fragmental products of explosive eruptions) are plotted. The effects of these larger
events are often regional, and therefore less likely to escape documentation even in remote areas. The frequency of these events has remained
impressively constant for more than a century, and contrasts strongly with the apparent increase of smaller eruptions with time.
Seeing "big" amount of eruptions and quakes in this time of internet&fast communications doesn't mean they weren't there when communication was
slow or lacked completely. Before telegraph there wasn't really effective way for sending news globally and human populations was very thin in places
which are currently populated.
Saying that sun's magnetic field has increased after 1901 is complete bull#, that text itself tells that it's based on that stuff itself... before
probes there wasn't any way to get data from sun's magnetic field.
Also it's strength/polarity varies in 11 year period, "after" that magnetic poles change places.
Also there couldn't have been any hard data from mangetic fields of Uranus and Neptune before Voyager 2... neither talking about after that, so
saying there's shift of magnetic field going on there is BS.
And neither there could have been hard data about Jupiter's magnetosphere, Galileo probe arrived to Jupiter on December 7, 1995.
Wake up nuts! Mars has seasons which change look of it from sizes of polar caps to "annual" dust storm covering whole planet. It's just that
instead of tilt of rotation axis seasons of Mars are caused by high eccentricity of its orbit.
Just to make few corrections...
