earthquake light (from Wikipedia):

An earthquake light, is an unusual luminous aerial phenomenon, that reportedly appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. Once commonly challenged, it was not until photographs were taken during the Matsushiro earthquake swarm, from 1965 through 1967, that the seismology community acknowledged their occurrence.

Wikipedia, about solar flares:

Classification

Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square meter, W/m2) of 100 to 800 picometer X-rays near Earth, as measured on the GOES spacecraft. Each class has a peak flux ten times greater than the preceding one, with X class flares having a peak flux of order 10−4 W/m2. Within a class there is a linear scale from 1 to 9, so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare. The more powerful M and X class flares are often associated with a variety of effects on the near-Earth space environment. Although the GOES classification is commonly used to indicate the size of a flare, it is only one measure. This extended logarithmic classification is necessary because the total energies of flares range over many orders of magnitude, following a uniform distribution with flare frequency roughly proportional to the inverse of the total energy. Stellar flares (and earthquakes) show similar power-law distributions.

Superflares, from wikipedia:

Superflares are very strong explosions of even Sun-like stars that increase their energy production about one million times more than the production made by a strong eruption. According to scientists, the cause for such an eruption can be the interaction of the star’s magnetic field and the magnetic field of a Jupiter-like planet.

Super flare stars

As of 2000, nine super-flare stars have been found, some of them similar to our Sun. During such an explosion, 100 to 10 million times as much energy is released as that released by the largest coronal mass ejections of the Sun.

Superflare on earth(?) SuperFlare audio story:

May 6, 2008: At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington—widely acknowledged to be one of England’s foremost solar astronomers—was in his well-appointed private observatory. Just as usual on every sunny day, his telescope was projecting an 11-inch-wide image of the sun on a screen, and Carrington skillfully drew the sunspots he saw.

Right: Sunspots sketched by Richard Carrington on Sept. 1, 1859. Copyright: Royal Astronomical Society: more.

On that morning, he was capturing the likeness of an enormous group of sunspots. Suddenly, before his eyes, two brilliant beads of blinding white light appeared over the sunspots, intensified rapidly, and became kidney-shaped. Realizing that he was witnessing something unprecedented and “being somewhat flurried by the surprise,” Carrington later wrote, “I hastily ran to call someone to witness the exhibition with me. On returning within 60 seconds, I was mortified to find that it was already much changed and enfeebled.” He and his witness watched the white spots contract to mere pinpoints and disappear.

It was 11:23 AM. Only five minutes had passed.

Just before dawn the next day, skies all over planet Earth erupted in red, green, and purple auroras so brilliant that newspapers could be read as easily as in daylight. Indeed, stunning auroras pulsated even at near tropical latitudes over Cuba, the Bahamas, Jamaica, El Salvador, and Hawaii.

Even more disconcerting, telegraph systems worldwide went haywire. Spark discharges shocked telegraph operators and set the telegraph paper on fire. Even when telegraphers disconnected the batteries powering the lines, aurora-induced electric currents in the wires still allowed messages to be transmitted.

GEOMAGNETIC PULSATIONS AND TUNGUSKA-1908
PHENOMENON

German, Boris
Institute for Physics of the Ukrainian Academy of Science

INTRODUCTION
In the early morning on June 30, 1908 at 7:15 (± 5 min) a.m. that correspond to 0:14 (± 5 min) UT, a powerful explosion occurred in the Kulik-caldera, Eastern Siberia. Scientists examining the area estimated that the explosion was equivalent to 5÷40 megatons of TNT. The blast felled trees in an area over 2,150 square km. Barometric and seismic disturbances from the explosion were recorded world-wide. For the first three nights after the Tunguska explosion, skies of Eurasia were exceptionally bright and then the effect abruptly disappeared. Although most observers generally accept that some kind of a celestial body, either a comet or an asteroid, could blow up, however, the main puzzle is the absence of space-body remnants in/on the ground in the affected region. And now, more 100 years later, the debate about the Tunguska event continues.
PULSATIONS IN KIEL AND THE VORTEX OF GRAVITY
Linear gravitational field equations, that are obtained from Maxwell’s equations by using gravitational vectors instead of electromagnetic vectors, have attracted the attention of scientists long ago. When Heavisidian monopoles are taken into account the equations can be modified by introducing two scalar fields. In 1969, J. Carstoiu [1] presented the so-called vortex field of gravitational force, comparable to the electromagnetic system.
For the first time vortical structures on the Sun were observed in 1857 [2]. On May 5, 1907 the same structures were registered on the sundisk again. A. Stentzel has paid attention to the effect of a 50-yr period of these structures. The effect of inversion of speeds for neutral points of polarization has been noted since May, 10th 1907 when the rate of increase of Arago point has exceeded the rate of increase of point Babine [3]. Obviously, this effect could correlate with above mentioned vortical structures on the Sun at that time. Increasing of the angular distance of neutral points (both Arago and Babine), which has begun on May, 1907, proceeded till the end of June, 1908. Exactly after the Tunguska explosion the maximum relative increase of the polarization for the whole period from 1905 till 1910 was recorded [4].

See the article.

Briefly, the article explains how a warmer planet have increased the rate and/or the power of precipitations.

Mh, well, while looking for a youtube video on the same argument I stumbled upon this..

…video, that shows a scenario in witch the planet becomes 5 degrees hotter than now (I guess 5 farenheit), brr.. HOT.

Ice in the north pole is going to melt.. THIS SUMMER.

I also found that interesting page:

A massive impact with an asteroid that measured around 400 miles across is the reason that Mars is a planet of two distinct halves, where the northern and southern hemispheres look different.

An ancient asteroid impact is thought to have dramatically changed the face of Mars

This strange feature was first observed by Nasa’s Viking missions to Mars in the 1970s and ever since scientists have puzzled over why there are relatively young, smooth, low-lying plains in the north and relatively old, heavily cratered highlands in the south.

The mystery deepened 20 years later, when the Mars Global Surveyor probe showed that the crust of the planet is much thicker in the south and also revealed magnetic anomalies in the southern hemisphere but not in the north.

The culprit was either some internal process related to the planet’s internal structure, or an ancient impact.

Now the theory that it was subject to a cataclysmic collision between 3.9 billion and 4.5 billion years ago has received strong support from computer simulations carried out by two groups.

A third study has identified what appears to be by far the largest impact scar found in our Solar System, four times bigger than the closest rival.

The latter analysis by researchers at Massachusetts Institute of Technology and Nasa suggests that a giant basin that covers about 40 percent of the surface of Mars, sometimes called the Borealis Basin, is actually the remains of a colossal impact very early in the solar system’s formation, measuring about the size of the combined area of Asia, Europe and Australia.

Planetary scientists at the University of California, Santa Cruz, were involved in both computer simulation studies – which also appear in the journal Nature – and come to the same conclusion: that Mars once collided with an object about one-half to two-thirds the size of the Moon, striking at an angle of 30 to 60 degrees to leave a massive oval shaped basin.

“It’s a very old idea, but nobody had done the numerical calculations to see what would happen when a big asteroid hits Mars,” said Dr Francis Nimmo, one of the authors. “The impact would have to be big enough to blast the crust off half of the planet, but not so big that it melts everything.”

The impact would have been a million-billion times more energetic than the atom bomb that exploded over Nagasaki, said another group member, Dr Craig Agnor of Queen Mary University, London.

“Whereas an atom bomb might destroy an area a few tens of miles wide, this impact overturned the surface of half the planet [an area thousands of miles wide].”

Dr Nimmo’s group worked out the impacts in two dimensions. The effects in three dimensions, but at a lower resolution, were tackled in the second paper is by Drs Margarita Marinova and Oded Aharonson of the California Institute of Technology, working with colleagues in California.

“The two approaches are very complementary; putting them together gives you a complete picture,” Dr Nimmo said. “The two-dimensional model provides high resolution, but you can only look at vertical impacts. The three-dimensional model allows nonvertical impacts, but the resolution is lower so you can’t track what happens to the crust.”

Shock waves from the impact would travel through the planet and disrupt the crust on the other side, causing changes in the magnetic field recorded there.

The predicted changes are consistent with observations of magnetic anomalies in the southern hemisphere. In addition, new crust that formed in the northern lowlands would be derived from deep mantle rock melted by the impact and should have significantly different characteristics from the southern hemisphere crust.

Certain Martian meteorites may have originated from the northern crust, Nimmo said. The study also suggests that the impact occurred around the same time as the impact on Earth that created the Moon.

There are one or two even larger impacts thought to have occurred in the early solar system – a controversial theory that there was one on the innermost planet Mercury, and a widely accepted one that the Earth was struck by a planet as big as Mars, melting the crust and ejecting it into space where some of it clumped together to form our moon.

But in both of those cases, the impacts were so enormous that they completely obliterated all visible signs of the event.

It is only through indirect analysis, including study of rocks brought back from the moon by the Apollo astronauts, that these giant ancient impacts have been reconstructed.

The new finding adds yet another major event to the growing list of large impacts that have been recognized over the last few decades as having the shaped the planets and moons of the solar system as we know them today.

“The early solar system was a very dangerous place to be a planet,” said one of the MIT team, Dr Jeffrey Andrews-Hanna, who did his study with Prof Maria Zuber and Bruce Banerdt of NASA-Jet Propulsion Laboratory. “But without those impacts, we wouldn’t have the planets as we know them today.”

The basin that resulted from the Mars impact, 5,300 miles across and 6,600 miles long, is about four times wider than the next-biggest impact basins known, the Hellas basin on Mars and the South Pole-Aitken basin on the moon.

“A key finding of our study is that the northern lowlands is actually elliptical in shape, and thus resembles other smaller impact basins such as Hellas and the South Pole-Aitken basin.”
