Mississippi, USA – Heavy rain brought severe flash floods to Mississippi on October 30 as authorities warned motorists to avoid driving. The National Weather Service in Jackson said water continued to cover roads across the region.

South Sudan – South Sudan’s President declared an emergency in three of the country’s regions as floods swept through communities, affecting about one million people. The affected regions, including Upper Nile, have oil fields and farmlands key to the recovery of a nation that’s struggling to halt a five-year civil war that killed around 400,000 people. Oil Minister Awow Daniel Chuang said Tuesday that flooding in Upper Nile posed a challenge to production of crude, although it didn’t affect output.

Global Warming

Sea Level Rise Underestimated

Scientists have dramatically underestimated the impact rising seas will have on cities around the world, according to research published in the journal Nature Communications on Tuesday.

One hundred and fifty million people are currently living in places that will be below the high-tide line in 30 years — three times as many people as the old projection methods estimated.

Their model paints a grim picture: whole swaths of Vietnam, Thailand, coastal China, India, Egypt and Iraq swallowed by ocean. Where previous estimates showed one percent of Thailand’s population would live in areas under water by 2050, the revised estimates puts the figure closer to 10 percent. In Vietnam, a quarter of the country’s residents — 20 million people — presently live in areas that will be flooded at high tide. Almost all of Mumbai, where 1.6 percent of India’s population lives, will be inundated.

Wildfires

Wildfires – California

The race to stop an inferno torching the Los Angeles area has gotten more dangerous as furious winds — some as strong as in a hurricane — stoke the flames. Gusts of up to 70 mph will fuel the Getty Fire through Thursday, threatening more than 7,000 homes, the Los Angeles Fire Department said. And that’s just one of at least 10 wildfires burning across California.

The newly formed Easy Fire quickly consumed 1,300 acres in Ventura County, officials said. It threatened 6,500 homes and forced school closures and evacuations.

About 26,000 people were forced from their homes by the Simi Valley fire. Power had been shut off in some areas, affecting almost a million people.

Disease

Dengue Fever – Central America

Central American countries in 2019 have seen an increased incidence of dengue fever, in fact, the cumulative incidence rate of dengue in the Central America region is higher than in the previous five previous years, with an incidence of more than 100 people with dengue per 100,000 people,

Flu, Pneumonia – Global

Despite large declines since 1990 in child deaths from pneumonia and the flu, these and other lower respiratory infections (LRIs) remain a leading killer of children under age 5. A new scientific study finds LRIs responsible for one in seven child deaths globally.

White-nose Syndrome – Bats

The U.S. Fish and Wildlife Service is announcing a $100,000 challenge to combat white-nose syndrome (WNS), a lethal fungus that has killed millions of bats in North America and pushed some native bat species to the brink of extinction. Funding will be awarded to individuals who identify innovative ways to permanently eradicate, weaken or disarm the disease.

Measles – Samoa and Tonga

In a follow-up on the measles outbreak in Samoa, health authorities say there have been 15 confirmed cases, including three deaths. In addition, 314 suspected cases – most of them children under the age of four are being investigated. Meanwhile in Tonga, an outbreak of measles has occurred following the return of a squad of Tongan rugby players from New Zealand where one player developed measles. Twelve other players were in the incubation period of the illness during travel back to Tonga and developed symptoms on 6th- 9th October.

Volcanos

Global Volcanic Activity – New Activity for the week of 23 October – 29 October 2019

Klyuchevskoy | Central Kamchatka (Russia) : A small amount of ash began to be visible in gas-and-steam emissions at Klyuchevskoy beginning at 1020 on 24 October, prompting KVERT to raise the Aviation colour Code to Yellow (the second lowest level on a four-colour scale). Later that day video images showed an ash plume rising as high as 6 km (19,700 ft) a.s.l. and drifting 40 km NE. The Aviation colour Code was raised to Orange. KVERT and the Tokyo VAAC noted that during 25-28 October ash plumes rose to 5.5 km (18,000 ft) a.sl. and drifted 15-20 km SE, E, and NW. A weak thermal anomaly over the volcano was identified on 18 and 24 October.

Kuchinoerabujima | Ryukyu Islands (Japan) : A large shallow earthquake at Kuchinoerabujima was recorded at 2133 on 27 October, prompting JMA to raise the Alert Level to 3 (the middle level on a scale of 1-5) within a few hours. The report also stated that the number of volcanic earthquakes had increased on 18 October. A large earthquake was also detected on 18 October but had occurred at a slightly deeper location (below the W part of Shindake Crater) than the 27 October event.

Pavlof | United States : AVO reported that after a small explosion at Pavlof was recorded on 19 October and before 25 October clear satellite and webcam views did not show any deposits associated with the event. Weakly elevated surface temperatures and a small steam plume were occasionally visible. No other activity was detected during 26-29 October. The Aviation colour Code remained at Yellow and the Volcano Alert Level remained at Advisory.

Shishaldin | Fox Islands (USA) : Pilot and local observations as well as webcam views all indicated that the incandescence at Shishaldin’s summit crater was from low-level Strombolian activity during 21-22 October. Seismicity and infrasound signals were consistent with low-level eruptive activity, and a steam plume was persistent. By 23 October lava had filled the crater and during 23-24 October overflowed the N crater rim. A 200-m-long lava flow on the N flank melted snow and caused a lahar which traveled 2.9 km and stopped at about 1,230 m elevation. A smaller lava flows caused a 1-km-long lahar to descend the NE flank. Spatter accumulated around the crater rim and melted snow. On 25 October AVO noted that trace ash deposits had extended at least 8.5 km SE. Low-level eruptive activity continued during 26-29 October. Seismicity remained elevated, with periods of high-amplitude tremor. Small explosions were recorded during 27-28 October. A satellite image from 28 October showed a 850-m-long SWIR anomaly on the NW flank from a lava flow. A central spatter cone was visible. Spatter deposits on the snow at the upper flanks was evident, and tephra deposits extended about 2.5 km N. The lahar on the NW flank branched extensively at lower elevations and was at least 5 km long. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.
