Storms and Floods

Tropical Storms

In the Western Pacific:

Typhoon Utor made landfall at 3:50 p.m. in Yangxi county in the city of Yangjiang in western Guangdong province in China after claiming at least 6 lives in the Philippines.

Heavy downpours have been reported in Northern Thailand. Several flash floods and landslides have been reported in Mae Sot and Phop Phra districts.

A cargo ship has sunk 80 km southwest of Hong Kong in the waves created by Typhoon Utor. Rescue teams from Hong Kong and the Chinese mainland have saved 21 crew members.

More than 158,000 people have been evacuated from Guangdong and Hainan province of China following a Red alert.

Deadly Lightning

Lightning in the Rolpa district of Nepal has claimed the lives of two people.

Five women were killed after being struck by lightning in separate incidents in Kaushambi and Uttar Pradesh, India.

Disease

Record Dengue Outbreak in Singapore

An unusually severe dengue epidemic in Singapore has claimed its fifth fatality this year, even as health officials try to beat back the city-state’s worst-ever outbreak of the tropical disease.

As of Tuesday afternoon, officials had logged 14,363 cases of dengue fever this year, according to the National Environment Agency. The scale of the current epidemic has surpassed that of Singapore’s worst dengue outbreak in 2005, when authorities logged 14,006 confirmed cases and 27 deaths.

Cholera Outbreak in Afghanistan

A cholera outbreak at a village in northeast Afghanistan has infected 1,492 people, killed a young woman and left another 100 in critical condition.

Serious measles outbreak hits Central Africa

A severe measles epidemic has affected the whole territory of the Central African Republic, which lacks any strong health infrastructure, Health Minister Aguid Sounouk announced Tuesday.

The minister blamed the spread of the disease on “outbreaks of measles in several administrative districts of the country where no action was organised to contain the epidemic” since December 2012.

At the time, the landlocked nation was undergoing an insurgency that led in March to the ouster of president Francois Bozize and placed power in the hands of a rebel coalition, which has since joined with other forces to form an interim government.

Wildfires

Wildfires in central Canada

Wildfires continue to be a problem in Canada. Currently in the central region, including the Northern Territories, Alberta, Saskatchewan and Manitoba, numerous fires were spotted by the Aqua satellite on this image captured on August 12, 2013.

In the past week, 508 new fires started in Canada, burning over half a million acres (208,308 ha). Most of the past week’s fires occurred from Manitoba westward, particularly in British Columbia, while Saskatchewan accounted for roughly half of the area burned. Seasonal fire occurrence remains below average, but the area burned to date is nearly double the 10-year average.

Volcanos

Roundup of Global Volcanic Activity:

El Hierro (Canary Islands, Spain): The number of earthquakes has increased from averages of 5-10 to about 30 during the past few days. The location of the recent quakes is in a N-S elongated layer about 10-12 km depth in the western part of the island under the El Golfo bay. So far, no quakes above magnitude 3 have occurred.

Tolbachik (Kamchatka): KVERT reports continuing lava effusion, but the slowly decreasing trend of tremor (2.1 mcm/s today) suggests that an end of the eruption is (slowly) approaching.

Kilauea (Hawai’i): The eruption continues with no significant changes; lava continues to flow into the ocean.

The lava lake inside Halema’uma’u crater at the summit caldera remains active with fluctuating levels.

Veniaminof (Alaska Peninsula, USA): A surge of activity seems to be taking place. Both visual and seismic activity have increased over the past 24 hours. An intermittent steam and ash plume has been observed rising to about 12,000 ft (3.6 km) asl. yesterday drifting into westerly directions.

Popocatépetl (Central Mexico): Activity has remained more or less at similar levels during the past days. During 11-12 August, CEAPRED reported 88 mostly weak emissions and a stronger explosion yesterday morning that produced an ash plume rising about 2.5 km above the crater.

Santa María / Santiaguito (Guatemala): Activity remains relatively elevated with occasional explosions producing ash plumes up to about 1 km height. Fine ash fall occurs in areas downwind in up to 10 km distance. The risk of lahars (mud flows) triggered by rainfall remains high.

Pacaya (Guatemala): INSIVUMEH reports weak strombolian activity.

Fuego (Guatemala): A slight increase of activity has occurred over the past dayss. The INSIVUMEH volcano observatory reported 11 strombolian explosions during the past 24 hrs interval with plumes rising up to about 600 m above the crater, and incandescent fragments ejected to 100 m above the crater, creating avalanches on the upper flanks.

Two lava flows remain active towards the Taniluya and Ceniza drainages on the southern slopes, with 300 and 400 m length, respectively.

Nevado del Ruiz (Colombia): Since the last update, the volcano has been relatively calm with only internal unrest in the form of fluctuating seismic activity. Manizales observatory reports a slight increase during the past week, with earthquakes clustered in the usual location (presumably an area of magma storage) about 3.5 km NE of the Arenas crater at depths between 4-7 km.
