Canary Islands - El Hierro Volcano : Green and Yellow alert – Continuing earthquakes and 50 earthquakes so far today. 224 quakes on Tuesday. Monday 245 quakes. Sunday 22 quakes. Seismic activity remained strong all night with regular strong volcanic earthquakes between 3.0 and 3.5 in magnitude. So far today IGN has listed 50 earthquakes, which is about the same than yesterday (a little less). 3 earthquakes were recorded as M3 or greater.
The magma is still imprisoned below the South-Western ridge of the island and the coastal El Julan area. Minor magma movement at this time. The magma has been gradually moving from the El Golfo island towards a cluster below the old volcano crater and finally towards El Julan (south coast). It still has to travel a little bit towards the submarine crater to restart the eruption process. The main question now is whether it will reach and reopen the cone or withdraw before that.
More strong earthquakes can be expected today or as always with volcanoes, everything can stop suddenly – all options are open. We can expect a little more information today regarding deformation and gas emission levels. (charts, photos, log of previous eruption activity, & a free earthquake notification service)

Russia - Shiveluch eruption continues. The Shiveluch Volcano, which is currently erupting in Kamchatka, threw up two pillars of ash, to a height of 6.5 km.

Tristan da Cunha - Scientists have used an advanced rock-dating technique to alert residents on the remote South Atlantic island of impending volcanos. In 1961, a volcanic eruption led to the total evacuation of Tristan da Cunha, the most remote inhabited archipelago in the world, with residents moved to temporary accommodation in the UK. The island, with a population of 261, is a British territory with only one village, which is called Edinburgh of the Seven Seas. The land mass is the tip of an undersea volcano and is seven miles across. Following their evacuation, families decided to return home in 1963. However, the volcano is still active and as recently as 2004 an undersea eruption washed volcanic rock on to the island’s shores. Now scientists have used a method known as argon-argon dating which shows eruptions are more common than previously thought. Although the scientists cannot give exact predictions, they have helped islanders be more aware of the risk of eruptions and encouraged them to review their disaster management plans. “We dated samples from as long ago as around 118,000 years to as recently as 3,000 years and discovered eruptions are much more frequent and recent than previously suspected.”

In the Atlantic -
Tropical storm Debby was located about 20 mi [30 km] ESE of Cedar Key, Florida. On the forecast track, the center of Debby will cross the northern Florida Peninsula this morning and possibly emerge into the Atlantic this afternoon or tonight. Debby is expected to produce additional rain accumulations of 2 to 3 inches over northern Florida with isolated 5 inch amounts possible. Isolated storm total amounts of 25 inches are possible in northern Florida.

In the Pacific -
Tropical storm 07w (Doksuri) was located approximately 360 nm east of Manila, Philippines.

Tropical Storm Debby weakened to a tropical depression after it drifted ashore on Florida's Gulf Coast on Tuesday, even as it dumped more rain on flooded areas and sent thousands of people fleeing from rising rivers. After stalling in the Gulf for two days, the large and ragged storm finally began moving eastward. The center crossed the shore late on Tuesday afternoon near Steinhatchee, in the Big Bend area where the Panhandle joins the peninsula, and later took an unexpected turn to the southeast.
Most of the thunderstorms and rain were northeast of the storm center and had already dumped 2 feet of rain over parts of Florida. Forecasters at the National Hurricane Center said Debby could bring another 4 to 8 inches of rain - and possibly tornadoes - to north Florida and southeast Georgia in the next two days. Debby's top winds weakened to 35 miles per hour (55 km per hour) on Tuesday evening, just below the threshold to remain a tropical storm. Little change in intensity was expected, as its center slogged across the northern Florida peninsula, and it was seen emerging over the Atlantic Ocean by this evening, where it could strengthen again into a tropical storm.
Though Debby was still a threat, the hurricane center said a tropical storm warning for the Gulf Coast of Florida had been discontinued. No coastal watches or warnings remained in effect. Emergency managers in Pasco County on Florida's central Gulf Coast ordered a mandatory evacuation for 14,000 to 20,000 people living between the Anclote and Pithlachascotee Rivers. The Anclote rose from 9 feet before Debby's approach to more than 27 feet, well above major flood level. Water was ankle-deep to head-high in the evacuation area. Emergency crews had to use boats to reach stranded residents in some areas, and 106 Pasco County homes had been damaged. "The city has always been prepared for a water event, but I think Mother Nature woke us up as to how fast she can operate."
The storm was piling up coastal waters and pushing them inland, preventing the rainwater from draining out to sea. Nearly 20 inches of rain has fallen in two days on Wakulla County. Roads were under water in many parts of the surrounding area. Parts of Interstate 10 were closed between the capital, Tallahassee, and the Atlantic coast city of Jacksonville. The storm left 29,000 people without power across the central and northern parts of the state. Debby spawned tornadoes that killed a woman, badly injured a child and wrecked homes in central Florida in rural Highlands County on Sunday. Florida's coastal Pinellas County was also hit hard, with flooding in some areas and at least 20 houses with roofs that were partially or fully blown off during a tornado-like storm.
Flash flood warnings were in effect for many areas and emergency managers cautioned that inland flooding was linked to more than half the deaths from tropical cyclones in the United States over the last 30 years. Debby was the first tropical storm of 2012 to disrupt U.S. energy operations in the Gulf of Mexico. Shutdowns peaked on Monday, when more than 44 percent of daily oil production and a third of daily natural gas production were closed. Energy companies began returning staff to offshore platforms after the storm veered away from the Gulf oil patch and production was rapidly being restarted.


Bangladesh - 51 people have been killed in landslides in southeast Bangladesh after three days of rains that triggered flash floods and severed transport links.


New Zealand narrowly missed a direct hit by what was essentially a winter cyclone, but that was no reprieve from cold, windy weather.


Wildfires worsen in Colorado - A wildfire raging near some of Colorado's most popular tourist sites grew suddenly more ferocious on Tuesday, forcing 32000 people from their homes, prompting evacuations from the US Air Force Academy and swallowing houses on the outskirts of Colorado Springs.
