Kansas, USA – Heavy rainfall throughout the night in south-central Kansas led to flash flooding and many school closures today. In Wichita, up to 10 inches of rain fell overnight, and flash flooding has continued throughout this morning. In addition, thousands of people in the area are without power because of gusty winds. Flash flood watches and warnings were issued for Kansas and Missouri this morning, as more rain is forecast for the area today.

Before and After Space Pics Reveal Massive Ice Avalanche

One of the world’s largest, and most mysterious ice avalanches was recently visualized in stunning pictures from space.

A huge sliver of ice split off from a vast glacier in the Aru Mountains of Tibet, falling nearly 0.6 miles (1 kilometre) before tumbling through a narrow gully and plunging into a nearby lake.

When the ice and rock settled, the avalanche debris spanned 4 square miles (10 square km) and was 98 feet (30 m) thick. The massive avalanche killed nine people, 350 sheep and 110 yaks that lived in the village of Dungru.

Disease

Leprosy Suspected in 2 California Kids

Two schoolchildren in California are suspected of having leprosy, but where might they have caught the disease?

This week, officials in Riverside Country (which is near Los Angeles) said they are investigating the suspected cases of leprosy, now usually called Hansen’s disease, at an elementary school in the area. Nursing staff at the school first notified officials about the possible infections on Sept. 2, but it will take several weeks to confirm them.

Cases of Hansen’s disease in the United States are rare, but they do occur, with about 100 to 200 cases typically reported each year, according to the Centres for Disease Control and Prevention.

Kala-Azar Outbreak in Upper Nile, South Sudan

Health authorities in South Sudan are collaboratively stepping up preventing measures to contain the increase in the number of cases of visceral leishmaniasis, commonly known as kala-azar in Upper Nile region.

So far this year, it added, 1,163 cases and 42 deaths (case fatality rate of 3.6 per cent) have been reported from 18 treatment centres. The majority were from Lankien (467), followed by Old Fangak (276), Melut (68), Kurwai (64), and Ulang (42). Suspected cases have also been reported in Baliet and Adong in Upper Nile.

Roundup of Global Volcanic Activity

Ruapehu (North Island): After reaching record-low temperatures in August, the volcano’s closely-monitored crater lake has started to heat up very quickly since 2 September, Geonet reported. Ruapehu’s crater lake displays temperatures that follow periodic cooling and heating cycles that range between about 15 and 40 °C. In mid August, a record-low of 12 °C was measured, but New Zealand scientists have detected a rapid increase in temperature over the past days, along with increased seismic activity inside the volcano. The highest-ever temperature of the lake, since it had reformed in 1999-2000 was 46°C on 11 May 2016. This peak was also accompanied by volcanic tremor and an increase in gas emissions. GNS Science back then raised the alert level to Level 2, but lowered it back to Level 1 in early July, when degassing and seismic activity became less. The heating and cooling cycles of Ruapehu’s crater lake are not completely understood, but caused by a mix of volcano and geothermal processes; a heating period usually indicates a period of higher volcanic unrest which includes a higher possibility of a new eruption to occur. For now, the alert level is not raised as the current signs of unrest are weak.

Nyiragongo (DRCongo): The activity at the volcano remains intense. The February 2016 side vent on the eastern lower terrace, which stopped in May and restarted in mid August, continues to be active, too. The now quite sizeable cinder cone built at the original fissure vent continues to contain a magma column degassing with strombolian-type explosions of fluctuating intensity and aliments changing lava flows that spread over the crater floor and occasionally cascade into the central lava lake.
