Residents in panic as Indonesian volcano erupts
One of Indonesia’s most active volcanoes, Mount Lokon, erupted on Tuesday. It has caused panic among villagers, but no evacuation has been ordered so far. Two villages of about 10,000 people each have been affected by the ash, which is now no longer being emitted, AFP quotes volcanologists from a monitoring post near the volcano on Sulawesi Island as saying. Lokon’s eruption in 1991 killed a Swiss tourist. When the volcano erupted in July, with huge clouds of ash as high as 3,500 meters, more than 5,200 people were evacuated.

Trying to keep up with the news at El Hierro in the Canary Islands is hard – the seismicity and tremor has been almost nonstop for 6 months now and over the last few weeks, the submarine eruptions have waxed and waned – but now we seem to have entered another period of strong submarine activity (see above), which might possibly be closer to the ocean surface.
UPDATE 3:15 EDT: It looks like the phreatomagmatic explosive activity is beginning south of El Hierro. Prensa El Hierro tweeted (translated): “Juan Manuel Santana have just announced that produce water columns and ash.” La Restinga is being evacuated as a precaution. Some new video/images of the area shows small explosive plumes/jets from the ocean surface that suggest the eruption is enterting a Surtseyan phase. Here is a live feed of TV from El Hierro with updates.
The current activity is pretty clear from a linear vent on the seafloor (see right) and there are very prominent bubbling areas where the volcanic tephra and gases are rising – with some excellent video to show that activity. This vent, as I’ve mentioned before, is likely to be very similar to what we see at Kilauea during new fissure vent eruptions – albeit that this one is under the sea. At the depths that the material is eruption (few hundred meters), the eruption is likely not highly explosive but plenty of shattered basaltic (or basanitic) glass is being produced as the lava hits the cold ocean water. Now, it does appear that the bubbling is more intense (video) – and more of it – so if these vents do begin to get close enough to the surface to produce ocean-surface explosions, we might expect something like the 2009 Hunga Tonga Hunga Ha’apai activity, also know as Surtseyan eruption. There has been more of the floating, dark pyroclastic material (see below) as well from the renewed activity at El Hierro.
All of this new activity has prompted the PEVOLCA to indefinitely close the tunnel to Frontera after earthquakes as large as M4.4 have occurred on El Hierro. New evacuations have also been called for people living on the southern end of the island due to the renewed eruptive activity. The government and IGN have had to quell rumors that eruptions have started to the north of El Hierro as well but there is no evidence of any activity other than the submarine eruption south of La Restinga. However, IGN “expects” eruptions to propagate northwardTrying to keep up with the news at El Hierro in the Canary Islands is hard – the... more

Everyone is wondering what would happen on March 19 or would be just another day? As the Moon is coming closer to Earth in almost 18 years, it may trigger natural disasters like earthquakes, volcanic eruptions and storms.

Ok, call me crazy, but even though I know what is being spewed out from beneath the Earth, some parts of this actually look beautiful to see. The Earth flexes its muscles and breathes just like humans do. And I do not know if this is a sign of anything other than the Earth flexing those muscles, but one thing is for sure...man is not omnipotent over nature and should never think he is. That kind of arrogance is what has brought us to the tipping point.
Description from video:

Hundreds of earthquakes rippled through Yellowstone National Park, Wyoming, in late December and early January, prompting fears that the shaking might trigger dangerous steam explosions.
Magma and steam permeate the rock beneath Yellowstone, and the motion of these fluids is thought to be responsible for the thousands of small earthquakes recorded in and around the park each year.
Crater evidence - Yellowstone, which sits atop a supervolcano, is pockmarked with craters thought to have been produced this way, and geologists estimate an explosion big enough to make a 100-metre crater happens there about every 200 years.
At the time of writing, though, the swarm was subsiding with no reports of such an event. "It hasn't stopped, but it has reduced markedly in the last couple of days," said Robert Smith of the University of Utah on Monday.
There are no signs of any on the way, either, said Smith, who monitors Yellowstone's geologic activity.
The quakes appear to be concentrated along a fault beneath the park. Further analysis should reveal whether they were triggered by forces associated with the fault, activity of hot fluids beneath the surface, or some other cause, he says.Hundreds of earthquakes rippled through Yellowstone National Park, Wyoming, in late... more
