Magnitude 5+ Earthquakes – Global

7.2 Earthquake hits Bohol in the Philippines.

The death toll from the 7.2-magnitude earthquake that struck the central Philippine island of Bohol on Tuesday rose to 93, as rescuers struggled to reach patients in a collapsed hospital. Centuries-old stone churches crumbled and wide areas were without power. The quake struck below the island of Bohol, known for its sandy beaches. People were killed as structures collapsed in Bohol and nearby Cebu province. Several buildings and churches were damaged by the quake.

The quake struck at 08:12 (00:12GMT) on a national holiday in the country. 16 people were confirmed dead in Bohol and 15 in Cebu, considered the Philippines’ second city. One was reported dead from the neighbouring island of Siquijor. Dozens of others were also being treated for injuries. At least five people died when part of a fishing port collapsed in Cebu. Two more people died and others were injured when a roof at a market fell. At least three people also died during a stampede at a sports complex in Cebu. “There was panic when the quake happened and there was a rush toward the exit.”

The tremor triggered power outages in parts of Bohol, Cebu and neighbouring areas. Cebu officials have declared a state of calamity in the province. People fled to the streets in Cebu, one of the country’s major cities, as buildings and homes were damaged . A city hall building was damaged on the island. Heavy damage to historic churches, some dating back to the Spanish colonial period in the 1500s and the 1600s, was also reported in Bohol and Cebu.

It was fortunate that it was a national holiday and the students were not in school. There were reports of many aftershocks following the quake.

Storms and Floods

Tropical Storms

In the Western Pacific:

Typhoon Wipha is located approximately 593 nm south-southwest of Yokosuka, Japan.

Huge and powerful Category 2 Typhoon Wipha is now weakening as it heads north towards Japan. The storm peaked as a Category 4 storm with 135 mph winds on Sunday, but has weakened to 110 mph winds. Today, Wipha will encounter cooler waters and higher wind shear, which should substantially weaken the storm as it recurves to the northeast and passes just offshore from Tokyo. The coast of Japan should experience winds below hurricane force, if the core of Wipha passes offshore as expected, but heavy rains of 4 – 8″ capable of causing damaging flooding will likely affect portions of the coast, including Tokyo. Heavy rains from Wipha may be a concern for the Fukushima nuclear site.

Typhoon Nari nearing landfall in Vietnam – Torrential rains are falling in Vietnam due to Category 1 Typhoon Nari, which is nearing landfall in the central part of the country. More than 180,000 people have been evacuated in advance of the storm. Nari battered the Philippines on Friday, killing thirteen people and leaving 2.1 million people without power on the main Philippine island of Luzon.

In the Eastern Pacific:

In the Eastern Pacific, we have two tropical cyclones: newly-developed Tropical Storm Priscilla, and Tropical Storm Octave. Octave is the only one that is a threat to land, and the 60-mph tropical storm is headed NNW towards Mexico’s Baja Peninsula, where 3 – 6″ of rain is expected over the next few days. Octave is expected to dissipate before making it to Baja, due to increasing dry air and wind shear.

Octave and Priscilla are embedded in a large plume of tropical moisture that is riding up to the northeast over Mexico and Texas. Flood watches and warnings are posted over many areas of Texas, where widespread rains of 2 – 6″ have fallen over the past day. While the heavy rains have caused some moderate flooding, the precipitation is mostly welcome, as it will make a substantial dent in the multi-year drought that has gripped much of Texas. Much of the moisture generating the heavy rains in Texas is actually coming from the Gulf of Mexico, due to the clockwise flow of low-level air around a high pressure system over the Upper Midwest.

In the Indian Ocean:

Phailin is officially the strongest tropical cyclone ever recorded to make landfall over India.

Flood waters have left nearly 100,000 people stranded in Mayurbhanj and Balasore districts. The death toll from the cyclone has risen to 27 in Orissa, with four people killed in the floods. A flood alert has been also sounded in the neighbouring state of Bihar. There are fears of heavy rainfall in at least two dozen districts after the weakened storm changed course and moved towards northern parts of Bihar bordering Nepal.

Space Events

All Sky Fireball Network

Every night, a network of NASA all-sky cameras scans the skies above the United States for fireballs – meteors brighter than Venus. Automated software maintained by NASA’s Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth’s atmosphere and many other characteristics. Daily results are presented on Spaceweather.com. On Oct. 14, the network detected 7 fireballs.

Wildfires

Australia – Record Heat

Fingal Bay, Port Stephens and Lake Macquarie were host to more than a dozen out-of-control blazes last Sunday.

The mercury soared to 35 degrees, fanned by 100 km/h winds and sparked fires in the early afternoon.

Hundreds of residents whose homes were under threat in the Tilligerry Peninsula were turned away at Lemon Tree Passage, which was blocked off at Rookes Road.

By 6pm Sunday, more than 50 residents had moved to an evacuation centre at Williamtown, having been denied access to the peninsula. Strong south-easterly winds pushed the flames towards Mallabula, Bobs Farm and Tanilba Bay.

In Salt Ash, it is believed five homes were gutted by the flames.

At Fingal Bay, a fire raged out of control at Rocky Point Road, Boulder Bay Road, Amaroo Crescent and Pacific Drive for most of the day.

Disease

Cholera in Mexico

A cholera outbreak in central Mexico has risen to 159 confirmed cases and spread to four states as well as the capital, the country’s health minister said on Monday.

One death has been attributed to the outbreak, the ministry said as it launched a nationwide public health campaign aimed at preventing further infections.

The east-central state of Hidalgo has been the worst affected with 145 confirmed cases, including the death of a 75-year-old woman. Also affected were the states of Mexico with nine, Veracruz with two, San Luis Potosi with one, and another couple in Mexico City, said Health Minister Mercedes Juan.

Eight in 10 cases have been successfully treated, the minister said, while those infected with the disease in the past several weeks range in age from three to 86.

She added that another 3,075 “probable cases” have been detected.

The source of the outbreak is believed to be the Rio Tecoluco in Hidalgo, which has tested positive for cholera and provides fresh water for local residents, said David Korenfeld, head of Mexico’s national water commission.

Cholera is an infectious and sometimes fatal disease of the small intestine, often accompanied by severe nausea and diarrhoea.

Volcanos

Roundup of Global Volcanic Activity:

Klyuchevskoy (Kamchatka): KVERT reported a small decrease in activity, although it seems during the past hours (after the report) to have increased again (see video below). The activity in any case can be considered high. An ash plume rises to up to 26,200 ft (8 km) a.s.l. and extends to the east-north-east of the volcano. Phreatic explosions (due to lava-snow interaction) at the south-western flanks of the volcano continue. Lava flows, fed by fountaining at the summit effuse on the south-western, western and south-eastern volcanic flanks.

Kizimen (Kamchatka): VAAC Tokyo reported an ash plume drifting at 13,000 ft (4 km) altitude from the volcano this morning at 05:28 UTC. Webcam images show a sustained steam-gas plume that might contain some ash. Glow from the summit lava dome can be seen on night-time images, indicating that lava extrusion continues.

Shiveluch (Kamchatka): The lava dome has become more active again, and frequently produces small incandescent avalanches. Strong degassing and occasional ash venting accompany this process. A weak ash plume rose today from the volcano to an altitude of about 12,000 ft.

Tangkubanparahu (West Java): No more eruptions have occurred since the series of 11 phreatic explosions between Saturday and Tuesday last week (5-8 Oct), but VSI continues to detect volcanic tremor. This suggests ongoing internal movements of pressurized fluids that could lead to new explosions any time. An exclusion zone of 1.5 radius around the crater is maintained.
