Strong Eruption With Small Pyroclastic Flows At Colima Volcano In Mexico
Explosions of various sizes continue to occur from the volcano’s summit vent. A particularly spectacular one this morning around 06:10 local time showered the summit cone with incandescent material and triggered small pyroclastic flows.

Alert Level Raised To Maximum 4 At Sinabung Volcano In Sumatra, Indonesia
The alert level of the volcano was again raised from “siaga” to “awas”, the highest on the Indonesian 1-4 scale. The reason is a currently elevated risk of possibly larger pyroclastic flows, that could be triggered by collapse of the increasing volume of the viscous lava lobe emplaced on the upper SE flank.
The alert level of the volcano had been at 4 during late Nov 2013 until April 2014,- the first and so far most violent phase of pyroclastic flow generation after the lava had spilled over the summit crater and built a large lobe that reached the base of the cone.

Since then, for more than a year now, lava effusion has continued at mild, more or less constant rate. Tremor data suggest that the supply rate of magma to the volcano’s summit has been more or less constant during the past year.
This activity produced successive lava lobes on the upper flank, all on top and/or at the upper sides of the main flow emplaced during the first months of the eruption. Associated avalanches and pyroclastic flows had mostly been smaller in comparison, although a few larger ones occurred as well.

However, the number of rock avalanches and pyroclastic flows has not been constant over time. It shows an amazing cyclic pattern at a rhythm of approx. 4-5 weeks for each. This corresponds to alternating phases of slow growth of a lobe, during which relatively few rockfalls occur, and a following period when the lobe is being destroyed by more frequent rockfalls / pyroclastic flows of various sizes.
Different to the previous episodes, the current lobe which appeared in late April has now become significantly bigger than its predecessors. Therefore, it could in turn also produce much larger pyroclastic flows if it collapses. Its volume has been estimated to be approx. 3 million cubic meters, about twice as the previous lobe that formed during late March-April.
The current lobe has even become large enough to overspill to the ENE side where a number of rock avalanches and smaller pyroclastic flows have started to occur, in an area that has not been touched for months.
Authorities started to evacuate more than 1,800 people from several villages (Jeraya, Mardinding, Sukanalu, Sigarang-fierce, Kutagugung, Lau Kawar) and the exclusion zone was increased to 7 km distance from the summit in the SE sector of the volcano.

Severe dust-storm causes blackout in parts of Karachi, Pakistan
A severe dust-storm paralyzed the Karachi Airport temporarily on Wednesday and also caused 50 feeders of KElectric (KE) to trip, causing a blackout in parts of the metropolis.
According to KElectric spokesman Usama Qureshi the dust-storm caused 50 out of 1400 feeders to trip. The spokesman added that strong winds caused billboards and trees to crash with power lines causing further outages.
Qureshi added, that KE teams were working on ground to restore power to consumers. He appealed to citizens to be wary of broken electricity wires and requested that any breakages be reported promptly to the distribution company’s hotline 118.

**MAJOR ALERT**MERS VIRUS EPIDEMIC TO SPREAD
MERS Virus Kills 5 More in South Korea
South Korea confirms 5 more cases of Middle East Respiratory Syndrome (MERS) virus on Wednesday.
The total number of people infected with the virus has climbed to 30 since the outbreak began two weeks ago, making it the third largest MERS outbreak outside the Arabian peninsula. The disease has killed two people since the first confirmed case was announced on May 20.
The situation has sparked a nationwide panic in the country and has shut off 200 schools, cancelled public events and quarantined or isolated more than a thousand people for possible infection, according to Reuters.
Travel authorities have banned individuals, who are suspected of being infected with the disease, to travel overseas.
South Korea President Park Geun-hye announced on Wednesday that everything must be done to stop the spread of the MERS virus.
“There are a lot people worried about the situation,” Park said, according to Daily Mail. “Everything must be done to stop any further spread.”
Given how the disease has spread fast and how many people have been exposed in the country, more infections are currently being anticipated, according to the statement released by the World Health Organization (WHO).
The two deaths announced on Tuesday confirmed that a 71-year old and 58-year old woman died after testing positive for the virus. They both got the infection from the first patient who returned from a business trip from the Middle East.
Most of the infected patients have been directly infected by the first patient.
However, the five new cases announced Wednesday morning were infected via third-generation of transmission. This means that the patients did not come into contact with the first patient but with intermediaries, who were also exposed to the disease.
The information and name of the hospitals that are treating MERS patients are still kept mum by public health authorities, according to Yahoo News.
They insisted that refusing to name the hospitals is “helpful” to the situation, but a list of rumored hospitals is already making rounds in the South Korean social media sphere.
A health expert opined that it may not be the right time to uphold the Korean tradition of visiting family and friends in hospitals.
“It may be the obligatory thing to go and comfort your family or friend, but that person has to rest … and in the current situation we’ve had cases where they were exposed while visiting hospitals,” Kim Woo-joo, of Korean Society of Infectious Diseases, said.
