Tsunami rumour in the Philippines

A Tsunami rumour in Quezon province in the Philippines has claimed life of an elderly woman who died after she had a heart attack on hearing the rumour.

Some 5,000 people also fled their homes after receiving text messages indicating a tsunami was coming from Batangas.

According to the Philippine Institute of Volcanology and Seismology (Phivolcs), it is impossible to have a tsunami alert at this time in any part of the country as there was no significant earthquake in the past 24 hours.

Storms and Floods

Tropical Storms

In the Western Pacific:

Typhoon Matmo is located approximately 106 nm south-southwest of Taipei, Taiwan.

In the Atlantic:

Tropical depression Two is located about 800 mi (1290 km) E of the Lesser Antilles. The Depression is expected to weaken as it approaches the Lesser Antilles.

NewsBytes:

India – Monsoon rains over the past week have caused floods in eastern India, killing three people and forcing thousands of families from their homes. Around 10,000 people have been evacuated to cyclone shelters in Odisha state’s worst-hit district of Jajpur after a major river burst its banks, flooding 30 villages. The deluge has also washed away roads, disrupted public transport, and inundated low-lying crop fields.

Largest-Ever U.S. ‘Critical Habitat’ Set for Loggerheads

Earlier this month, sea turtles gained a huge victory when the U.S. federal government announced the largest designation of critical habitat in the nation’s history for the loggerhead sea turtles on the Atlantic Coast and in the Gulf of Mexico. The National Marine Fisheries Service and the U.S. Fish and Wildlife Service made a joint announcement last week to designate 685 miles of beaches and more than 300,000 square miles of ocean as protected habitat for the creatures and their ecosystem.

Loggerheads spend most of their lives in the water, where they migrate tens of thousands of miles over their lifetimes to feed, grow, mate and nest. Unfortunately, fulfilling those basic needs puts them in harm’s way.

From birth, hatchling loggerheads are already at risk from being trampled by beach traffic or disoriented by artificial lighting, as they are hardwired to navigate by the moon’s light. If they safely reach the water, they find cover and food in mats of Sargassum algae, but must be careful not to ingest the millions of small pieces of plastic that also accumulate in the floating plants. As the young sea turtles grow into adults over the next twenty years, they can be captured in fishing gear, hooked on longlines, hit by speeding boats or coated in oil. Threatened by human activities throughout their entire lives, it is no surprise that this and other sea turtle populations have precipitously declined over the last decades.

Middle East respiratory syndrome coronavirus (MERS-CoV) – update

On 12 July 2014, the National IHR Focal Point of the Islamic Republic of Iran reported to WHO an additional laboratory-confirmed case of infection with Middle East respiratory syndrome coronavirus (MERS-CoV).

Brain disease kills scores in India’s east

An outbreak of encephalitis has killed 60 people in two weeks in the eastern Indian state of West Bengal, a top health official has said, calling the situation “alarming”.

Hundreds of mainly children die across India each year from the mosquito-borne virus, but West Bengal is not normally one of the worst-hit states.

Only five people died last year in West Bengal from Japanese encephalitis, one form of the virus which normally hits during the monsoon season when mosquitos breed.

West Bengal health services director Biswaranjan Satpathy said late on Monday there had been a sudden rise in cases and deaths between July 7 and 20.

Roundup of Global Volcanic Activity

Askja (Central Iceland): A large landslide occurred from the southern wall of the Askja caldera yesterday night. The slide caused a large flood wave in the Öskjuvatn lake that also swept into the famous Viti crater. There are no reports of victims. Although there have been speculations that the slide could have been triggered by magmatic processes, it is most likely a result of summer warming, melting frozen soil in the caldera walls, destabilizing it.

Zhupanovsky (Kamchatka, Russia): Several small ash emissions occurred at the volcano during 16-21 July. The resulting plumes dissipated quickly. Aviation color code is at orange.

Aso (Kyushu): Activity remains elevated at Asosan volcano. Although no new ash emissions were reported recently, the Nakadake crater shows intense degassing and bright glow from hot fumaroles is visible at night. It seems that the crater lake which usually occupied the bottom of the crater has evaporated.

Semeru (East Java, Indonesia): Activity, weak during the past months, seems to have picked up. A new lava flow has started to slowly descend the southeastern slope. Since the intense explosive phase of activity in February 2012, accompanied by pyroclastic flows down the southern slope, a lava dome has been growing slowly inside the breached summit crater. This dome now started to form a more or less coherent lava lobe that began descending through the notch onto the upper southern slope. Weak glow is visible at night.

Shishaldin (United States, Aleutian Islands): According to the Alaska Volcano Observatory, weak activity continues. MODIS data show elevated surface temperatures in the summit crater, but there are no visual or other indicators of eruptive activity available.

Semisopochnoi (United States, Aleutian Islands): Earthquakes have decreased but are still above background levels. No eruptive activity has been recorded. Alert level remains yellow.

Santiaguito (Guatemala): No explosions were observed since yesterday, but the lava flow at the eastern rim of the Caliente dome remains active, producing rockfalls into the Nima 1 river canyon. Strong degassing is occurring from the dome.

Fuego (Guatemala): No significant changes in activity have occurred at the volcano. The observatory reported 8 weak and one moderate strombolian-type explosion since yesterday. Ash plumes rose up to 800 m above the crater, and produced avalanches of glowing material on the upper slope. No lava flow was active.

San Miguel (El Salvador): The volcano continues to produce important gas emissions as well as occasional small ash explosions. Tremor remains at very high levels (20 times above normal), caused by internal fluid movements. The likelihood of new eruptive activity in the near to medium future remains elevated.

Cerro Negro de Mayasquer (Colombia): Seismic unrest continues at the volcanic massif of Chiles and Cerro Negro. However, it decreased during the past week with less than 700 events recorded, compared to 1500-1800 per week during the month before. Most earthquakes were associated with internal rock fracturing and located at shallow 1-7 km depth in an area 4 km SW of the Chiles dome. Magnitudes reached 2.7 and some quakes were felt. Slight deformation has been detected at the Chiles dome as well.

Reventador (Ecuador): Intermittent small explosions continue as well as slow lava extrusion at the summit, evidenced by thermal hot spots visible on satellite data.

Ubinas (Peru): The volcano has been relatively calm over the past days, producing mostly a very weak gas plume with dilute ash, as well as sporadic small explosions.
