eklemetti | July 10, 2009Another fun weekend for me analyzing zircon on the SHRIMP-RG at Stanford University! I really know how to live it up during the summer.
Some news bits:

In another sign that Redoubt's 2009 eruption might be at an end, AVO has ceased 24 hour staffing of their operations center. They still warn that Redoubt might still have more activity up its sleeve, but as of now, things are pretty quite. The latest update on Redoubt reports that the new dome continues to steam away and seismicity…
edyong | July 9, 2009As the world is now painfully aware, pigs can act as reservoirs for viruses that have the potential to jump into humans, triggering mass epidemics. Influenza is one such virus, but a group of Texan scientists have found another example in domestic Philippine pigs, and its one that's simultaneously more and less worrying - ebola.
There are five species of ebolaviruses and among them, only one - the so-called Reston ebolavirus - doesn't cause disease in humans. By fortuitous coincidence, this is also the species that Roger Barrette and colleagues have found among Philippine pigs and even…
eklemetti | July 8, 2009All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!
Highlights (not include Manda Hararo, Kilauea and Mayon) include
San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002.
A pilot spotted a ~10,000 foot / 3 km ash plume emanating from Anak Krakatau in Indonesia.
Another ash plume, this time at Ubinas, Peru, was spotted by pilots rising to ~6.7-9.1 km / 20-30,000 feet.
Explosions were heard from Suwanose-jima in Japan, but no associated ash plumes were spotted.
It sounds like a lava dome has been…
eklemetti | July 8, 2009Two papers submitted, one to go. Keeps you quite busy, let me tell you.
Lava flow from a 2006 eruption on Mayon in the Philippines.
A few bits of news today:
A few more details about the ongoing watch of Mayon in the Philippines . There have been apparently no changes in the shape of the floor of the crater as you might expect if magma was rising underneath. However, there has been an overall inflation of Mayon since the unrest began a few weeks ago. PHIVOLCS will be checking the sulfur dioxide and carbon dioxide output of the volcano soon as well.
Lots of articles this week about the "…
eklemetti | July 6, 2009Sorry about the lack of posts - the holiday and "real life" had stepped in the way.
On with the news!
Mayon Volcano in the Philippines with Legazpi City in the foreground.
Mayon, one of the most active volcanoes in the Philippines, is causing concern due to increasing signs of activity. Renato Solidum, the director of PHIVOLCS (Philippine Institute of Volcanology and Seismology), said that there has been increasing seismic activity and "glow" at the summit of the volcano near (~20 miles / 45 km) Legazpi City. However, even after this sense of increasing activity, the alert level (1) has not…
eklemetti | April 8, 2009Canlaon volcano, Philippines
Geothermal energy is one of those sources of energy that might be able to solve a lot of the planet's energy problems - heck, the Earth has a lot of heat it is trying to get rid of, so taking that heat and turning into energy seems like an easy (and clean?) way to stop using fossil fuels and the like. Of course, like any supposed panacea, it has its problems.
However, one aspect that gets people are riled is whether drilling into areas of active magmatism might actually cause volcanism. Just in the last few weeks, a controversy was sparked in the Philippines when…

So, there has been a lot of talk about "volcano monitoring" over the last 24 hours, now hasn't there?
Now, I'm not going to revisit this discussion, but as an example of why it might be important, there is an article today about the location of the Bataan Nuclear Power Plant in the Philippines (near the potentially active caldera Natib). These are the sorts of issues that need to be dealt with in regards to volcano monitoring - the cascading effect of an eruption. During the 1980 eruption of Mt. Saint Helens, there was a chance that volcaniclastic sediment from the eruption could have dammed…
edyong | January 22, 2009The area collectively known as Austronesia covers half the globe. It stretches from South-East Asia and Taiwan, across New Guinea and New Zealand, to the hundreds of small islands dotted around the Pacific. Today, it is home to about 400 million people.
They are the descendants of early humans who spread throughout the Pacific in prehistoric times. These forebears are long dead but they left several unexpectedly important legacies that are evident in their modern descendants. The languages they used evolved and splintered into over 1,200 tongues spoken by modern Austronesians. The bacteria…

Two volcanoes on the island of Luzon look like they might be primed for activity, at least according to PHILVOLCS, the Philippine Institute of Volcanology and Seismology. Both Mayon and Taal (above) are showing signs of increased seismicity. Only Mayon is actively steaming right now and the volcano had a mild ash eruption on August 10 as well. Officials in the Philippines have both volcanoes on Alert Level 1 (potential activity).
Taal is actually part of a bigger system that occupies a 15 by 20 km caldera. The island where most historic activity has occurred is made up of a series of…

We had a brief bit over the weekend that Mayon in the Philippines had a number of small explosive events (less the one minute worth of activity). However, Philvolcs (Philippine Institute of Volcanology and Seismology)Â is downplaying the idea that a major eruption is in the works. There have been a number of explosion-related seismic events and harmonic tremors, along with 12 mm of inflation on one side of the volcano (although over what time period the inflation occurred is not mentioned in the article). It appears that the Philvolcs scientists just think that magma is moving under the…

Mayon, a volcano in the Philippines, is on watch for an eruption after experiencing small explosions. Philvolcs, (short for the Philippine Institute of Volcanology and Seismology), reports a small ash emission - ~200 feet - but they feel that there isn't an imminent threat of an eruption. Mayon is an relatively active volcano in the Philippines, last erupting in 2006 and is well known for its prototypical conical volcano shape (see above).
zooillogix | June 30, 2008Tarsiers are prosimian primates, sharing their primitive grouping with lemurs, bushbabies and the aye-aye. However, due to numerous similarities to ancestral monkeys, apes and humans, there is some disagreement as to whether tarsiers should be grouped with the other prosimians in the Suborder Strepsirrhini or with the monkeys and friends in the Suborder Haplorrhini. The tarsier finds all of this debate quite dull and prefers to spend its time eating insects and bird eggs.
These pictures were taken by our friend's father in the jungles of the central Philippines.
They look pissed.

zooillogix | September 17, 2007Benny and I love almost all living things even if we have to squish those things from time to time. The one distinct exception to this rule is the earwig. This is the common name for the insect order Dermaptera, which frequently have an abdomen that ends in forceps-like cerci or, in other words, pinchers!
Earwig in a typical threatening posture
The earwig was the bane of our existence growing up. Gathering en masse in damp, dark places, they were particularly fond of the area where the fence gate met the first post, which divided our front and back yard. Such was our extreme fear of these…
