The Popocatepetl volcano registered 38 exhalations in the last 24 hours and one on the morning of Tuesday, was accompanied by slight amount of ash, as reported by the National Center for Disaster Prevention (Cenapred). In his report at 11:00 hours, indicated that all the exhalations of the last 24 hours were of low intensity, of which the most important were: one at 15:47 hours on Monday, another at 3:23 and most recently at 8:29, which was accompanied by ash. Bad weather conditions that prevailed during the Monday afternoon and Tuesday morning has obstructed visibility and, therefore, it is unclear which direction dispersed emissions from the volcano traveled.

From the morning until the time of writing this report there is a plume of water vapor and gas that rises a few meters above the crater, due to strong wind that goes to the northwest. The report makes no reference to seismic activity associated with the volcano or possible ashfall in neighboring towns.

Residents in a Cumberland County, N.J., community were left wondering what caused dozens of birds to drop dead from the sky earlier this week.

Increased concentrations of red tide algae likely left hundreds of thousands of dead fish washed up over the weekend on Galveston beaches, the Galveston County Daily News reports.

Low to moderate concentrations of the neurotoxic algal bloom were the probable cause of the fish kill that left the huge numbers of dead shad - also known as Gulf menhaden - on the island's West End beaches, an official told the newspaper, after testing revealed the presence of red tide.

The Galveston Island Park Board of Trustees brought in extra workers to deal with the fish kill and said it would clear the fish away by Wednesday if there were no more fish kills.

The presence of the algae prompted the Texas Department of State Health Services on Monday to close what little oyster harvesting was ongoing by public lease holders in Galveston Bay, department spokesman Chris Van Deusen told the newspaper.

Flooding caused by heavy rains in central Nigeria has killed at least 28 people, with many others still missing, while also destroying homes, bridges and farmland, officials said Tuesday.

"I have counted 28 bodies and many people are still missing after the flood," said Kemi Nshe, local government chairman for the Shendam district in central Nigeria's Plateau state.

He said some 1,500 people were displaced from the rains, the worst of which occurred Sunday.

A Red Cross official in the area said relief workers were having difficulties accessing flooded areas, which he said included around five communities. He said heavy rain began Saturday night and continued into Sunday.

After a 2011-2012 winter that saw little snow, the mid-Atlantic and southern New England states will get a snow dump this winter, forecasters say. Above-normal snowfall during winter 2012-2013 is forecast for the major I-95 cities including New York, Philadelphia, Baltimore and Washington, AccuWeather.com reported Wednesday.

"The I-95 cities could get hit pretty good," forecaster Paul Pastelok said. "It's a matter of getting the cold to phase in with the huge systems that we are going to see coming out of the southern branch of the jet stream this year."

This short paper is a preliminary examination of BEST data to 1753, as compared to the Central England Temperature Record (CET) to 1660 (instrumental record) and 1538 (Extended by Tony Brown using thousands of contemporary observations).

This extension to 1538 was a central part of my article 'The Long Slow Thaw,' which also examined historic temperature reconstructions by Dr Michael Mann and Hubert Lamb.

In the article, warming from the start of the CET instrumental record in 1660 to the present day was noted, albeit with numerous advances and reverses.

The extended CET record coincides well with a 2000 year reconstruction by Craig Loehle here.

And one by M. V. SHABALOVA and A. F. V. VAN ENGELEN : 'Evaluation of a reconstruction of winter and summer temperatures in the Low Countries, ad 764 - 1998' here.

According to studies made by a number of climate scientists, CET is a reasonable proxy for Northern Hemisphere -and to some extent global temperatures- as documented in 'The Long Slow Thaw'. However, as Hubert Lamb observed, it can 'show us the tendency but not the precision'. In that light there are a number of comments that can be made about the Combined CET/BEST graph which are shown above in two versions that, viewed together, provide the opportunity to follow the ups and down of the ever changing climate over the 350 years of instrumental records.

(Note; The BEST extension to 1538 and the extension to both trend lines after 2012 in the first graphic are merely a graphing feature.)

The recent increase in seismic activity under Sotarà volcano prompted INGEOMINAS to raise the alert level from yellow (unrest) to orange (eruption warning) yesterday afternoon.

The increase had been detected on June 24, 2012 and since that date, 6891 earthquakes have been recorded, i.e. an average of 150 quakes per day. Most of them (5177) are of very small magnitude, but the remaining 1714 quakes were of significant energy (local magnitudes 0.1-2.2) and concentrated in an area between 0.1 and 5 km northeast of the volcanic summit at depths between 2 and 6 km.

None of these events were felt by inhabitants of the communities surrounding the volcano Sotará.

The deformation network shows a possible inflation process towards the northeast sector of the volcano, which correlates with the epicentral zone of seismicity reported and suggest that magma is rising there, and might (or might not) lead to an eruption in a near to medium future.

During the month of July, geochemical surveys showed no significant changes in temperatures of hot springs in the area.

INGEOMINAS stresses that this activity does not pose any immediate danger to the communities aroud the volcano. However, it should be said as well that this could change quickly.

The source of an enormous floating mass of pumice spotted this week in the South Pacific Ocean off the coast of New Zealand has been discovered: NASA satellite images and other sleuthing science have pinpointed an erupting undersea volcano called the Havre Seamount as the culprit.

On Aug. 9, the HMNZS Canterbury ship observed the floating pumice "island" - measuring a whopping 300 miles (482 kilometers) in length and more than 30 miles (48 km) wide - along a voyage from Auckland to Raoul Island, New Zealand. A maritime patrol aircraft, RNZAF Orion, had seen the weird mass and reported it to this Royal New Zealand Air Force ship. Soon after, the HMNZS crew saw the thick mass of porous rocks.

"The rock looked to be sitting two feet above the surface of the waves, and lit up a brilliant white colour in the spotlight. It looked exactly like the edge of an ice shelf," said Lieutenant Tim Oscar, a Royal Australian Navy officer, in a statement.

Pumice, which forms when volcanic lava cools quickly, is riveted with pores due to gas getting trapped inside as the lava hardens. The result: lightweight rocks that can therefore float. (Recent research suggests such pumice replenishes the Great Barrier Reef with new coral.)

Where the huge floating mass came from was a mystery. At the time, according to the Royal Navy, scientists thought an underwater volcano, possibly the Monowai seamount, which has been erupting along the so-called Kermadec arc, was responsible. [See Photos of the Pumice Raft]

A magnitude 7.7 earthquake in a sea off the coast of eastern Russia did not cause any reported damage or injuries.

But it did cause numerous "false positive" reports of earthquakes in California, a U.S. Geological Survey official said Monday night.

The temblor struck Monday night PDT (1 p.m. local time) under the Sea of Okhotsk. Officials said it was 373 miles below ground and did not result in any tsunamis.

But for reasons that are not entirely clear, it triggered several erroneous reports of quakes in California.

Leslie Gordon, USGS spokeswoman in Menlo Park, said the false reports of earthquakes in Gerber, the Monterey area and Gilroy were triggered by the Russian quake. Those reports were retracted within minutes, Gordon said. A couple of the reports were erroneously reissued, then retracted again.

False reports occasionally are registered by USGS automatic earthquake sensors, she said.

Earthquakes are among the most destructive and common of geologic phenomena. Several million earthquakes are estimated to occur worldwide each year (the vast majority are too small to feel, but their motions can be measured by arrays of seismometers). Historically, most of Arizona has experienced low levels of recorded seismicity, with infrequent moderate and large earthquakes in the state. Comprehensive analyses of seismicity within Arizona have not been previously possible due to a lack of seismic stations in most regions, contributing to the perception that widespread earthquakes in Arizona are rare.

Debunking that myth, a new study published by Arizona State University researchers found nearly 1,000 earthquakes rattling the state over a three-year period. Jeffrey Lockridge, a graduate student in ASU's School of Earth and Space Exploration and the project's lead researcher, used new seismic data collected as part of the EarthScope project to develop methods to detect and locate small-magnitude earthquakes across the entire state of Arizona. EarthScope's USArray Transportable Array was deployed within Arizona from April 2006 to March 2009 and provided the first opportunity to examine seismicity on a statewide scale. Its increased sensitivity allowed Lockridge to find almost 1,000 earthquakes during the three-year period, including many in regions of Arizona that were previously thought to be seismically inactive.

"It is significant that we found events in areas where none had been detected before, but not necessarily surprising given the fact that many parts of the state had never been sampled by seismometers prior to the deployment of the EarthScope USArray," says Lockridge. "I expected to find some earthquakes outside of north-central Arizona, where the most and largest events had previously been recorded, just not quite so many in other areas of the state."
