Storms and Floods

Tropical Storms

In the Atlantic Ocean:

Tropical depression Five is located about 80 mi (30 km( SE of the southernmost Cape Verde Islands, where a tropical storm warning has been issued. The depression is expected to become a tropical storm today.

In the Western Pacific:

Typhoon Utor is located approximately 157 nm westward of Hong Kong. Now weakening rapidly due to land interaction. The last advisory has been issued on this system.

Floods in Kashmir, India

Floods in Jammu and Kashmir floods have claimed the lives of at least ten people including four children. 50 people were rescued while 17 are still reported to be trapped.

Global Warming

Climate Change Has Arrived in California

A new State of California report verifies what scientists have been telling the public for some time — climate change is here, and it is now affecting California’s water supplies, farm industry, forests, wildlife and public health.

Among other findings, the report concluded that:

Warming temperatures have accelerated since the 1970s, with nighttime temperatures increasing much faster than daytime;

Changes in precipitation patterns have had the effect of decreasing water supplies, even when overall rainfall remains the same;

Carbon dioxide levels in coastal waters are harming species and having effects throughout the marine food chain;

Over the past century, water levels have risen along the California coast by an average of 7 inches (18 centimeters), and levels have risen by 8 inches (20 centimeters) at the Golden Gate;

Annual acreage burned by wildfires since 2000 is double the rate of the previous 50 years, from less than 300,000 acres to almost 600,000; and

It may have triggered a growth spurt in two of California’s iconic tree species: coast redwoods and giant sequoia.

Wildfires

Wildfires USA

A lightning-sparked wildfire fanned by high winds has destroyed at least a dozen homes as it threatens hundreds of others near Park City, a Utah resort town where firefighters prepared to battle the blaze for a second day Wednesday.

The blaze was among several others in the West, where fires have devoured dry grass and brush and burned to the edges of small communities in several states. In about a dozen Western states, crews were actively fighting fires where drought has dried out landscapes and contributed to extreme fire behaviour.

Foot and Mouth Disease in Tibet

An outbreak of foot-and-mouth disease has been confirmed in cattle in southwest China’s Tibet Autonomous Region.

Roundup of Global Volcanic Activity:

El Hierro (Canary Islands, Spain): Earthquake activity has been calmer today. So far, only 9 tiny quakes (all below magnitude 2) have been recorded under the island.

Shiveluch (Kamchatka): Explosions continue to occur frequently. Several eruptions during the past 48 hours produced ash plume rising to about 20,000 ft (6 km) altitude.

Sakurajima (Kyushu, Japan): Explosions have been averaging to about 2-3 per day over the past week. Many of them have been moderately large with plume heights reaching 10,000 ft (3 km) altitude. An SO2 anomaly from this activity is visible hovering above the Kagoshima Bay and Sakurajima volcano.

Marapi (Western Sumatra, Indonesia): The volcano continues to produce small explosions every now and then. Local press reported two small eruptions this morning. The first one occurred at 7:49 am (local time WIB), producing an ash plume of 300 meters height, and the second at 8:32 am with an ash plume rising 600 meters.

Ambrym (Vanuatu): The lava lakes inside the Benbow and Marum craters continue to be active, a recent NASA satellite image shows.

Yasur (Tanna Island, Vanuatu): Strombolian activity has been decreasing according to GeoHazard, and the volcano could soon be placed back to alert level 1. However, bombs are still often being ejected outside the crater during larger strombolian eruptions, as the attached webcam image shows.

Gaua (Vanuatu): A tendency of increasing seismic activity has been observed since June and GeoHazards keep a close eye on the volcano, which still remains at alert level 1 (on a scale of 4) for the moment. Areas within 3 km from the crater and the summit area should not be approached, today’s new volcanic activity bulletin reads. Satellite images show what is most likely a weak degassing plume from the volcano’s main vent, Mt Garet on the shore of the caldera lake. The presence of the lake increases the risk of (usually sudden) phreatic explosions.

Popocatépetl (Central Mexico): At 19:02 h (local time) yesterday, an phase of strong ash emissions occurred accompanied by strong volcanic tremor. Due to cloud cover, the eruption was not observed directly, but fine ash fell in areas west of the volcano, including the towns of Ozumba and Tepetlixpa in the State of Mexico.

Tungurahua (Ecuador): Since 2 August, surface activity has decreased significantly, but seismic and deformation monitoring suggest the arrival of a new batch of magma from depth in the near future. Visually, no more explosions have been observed since 31 July and no ash emissions since 3 August. Gas emissions have been declining as well.
