The Wettersegen Prayers are said after the Last Gospel in German Speaking countries, asking for good weather and protection from storms. These prayers are said in the spring and summer, though the dates on which they start vary. They generally begin on the Feast of the Discovery of the True Cross (May 3), or the Feast of St. Mark (April 25, the Greater Litanies) while in other places on the Feast of St. George (April 23),  These prayers end on the Feast of the Exaltation of the Holy Cross (September 14). The blessing may be simple, or given with a Relic of the True Cross. In some places, bells are rung as at Benediction.

August 24, 79: Mount Vesuvius erupts.

Much of what is known of the catastrophic eruption of Mount Vesuvius comes from the descriptive epistles of Pliny the Younger (nephew of Pliny the Elder), who wrote that the event, which buried the nearby cities of Pompeii, Herculaneum, Stabiae, and others, was preceded by a series of small earthquakes that were not then recognized as precursors of the destruction that was to come. By all accounts, nearly everyone living within reach of the volcanic destruction was caught unprepared when Mount Vesuvius finally erupted - ejecting thick clouds of stone and ash into the air, and engulfing the cities in pyroclastic material, layered several feet thick.

Between 16,000 and 20,000 people were killed in the destruction, either from inhaling deadly gas fumes, from suffocation through ash inhalation, or from being struck by pieces of debris and rock. The subsequent rainfall turned the layers of ash and volcanic material which covered Pompeii into a kind of natural concrete, hiding and preserving the city until its rediscovery in the 16th century. Herculaneum was not rediscovered and excavated until 1738. 

Excerpt from one of Pliny’s letters/accounts of the eruption:

Ashes were already falling, not as yet very thickly. I looked round: a dense black cloud was coming up behind us, spreading over the earth like a flood.‘Let us leave the road while we can still see,’ I said, 'or we shall be knocked down and trampled underfoot in the dark by the crowd behind.’ We had scarcely sat down to rest when darkness fell, not the dark of a moonless or cloudy night, but as if the lamp had been put out in a closed room.

A few days ago, my father – a retired professor of architecture and urban planning at the University of Virginia – forwarded me this map that Rachel Nelson, a master’s student in Urban and Environmental Planning at UVA, made for an Intro to GIS class. Nelson’s map shows dangerous places in the United States based on natural disaster data. Given that the end of the world is scheduled for sometime tomorrow, I figured the map was worth sharing, both for its informational and its visual interest. Writes Nelson via email:

As a dedicated worrier, I wanted to use GIS to investigate where the most dangerous places to live in the US might be based on natural disaster data. I narrowed the criteria down to volcanoes, hurricanes, earthquakes, tornadoes and storms with hail bigger than tennis balls (2.4") or softballs (4"). The tornado and hail data tracks all storms over the past 60 years to get a visual for general patterns. Earthquake contour lines show predicted hazard zones based off of past activity and fault locations at 10% probability of exeedance in 50 years. Triangles map active US volcanoes, which are all presently at “low” risk.

Typhoon Kills At Least 283, Hundreds Missing, In Philippines

Blocked roads and severed communications in the southern Philippines frustrated rescuers on Wednesday as teams searched for hundreds of people missing after the strongest typhoon this year killed at least 283 people.

Typhoon Bopha, with central winds of 120 kph (75 mph) and gusts of up to 150 kph (93 mph), battered beach resorts and dive spots on Palawan island on Wednesday but it was weakening as it moved west.

Hardest hit was the southern island of Mindanao, where Bopha made landfall on Tuesday. It triggered landslides and floods along the coast and in farming and mining towns inland.

Interior Minister Manuel Roxas said 300 people were missing.

Entire families were washed away,” Roxas, who inspected the disaster zone, told reporters.

Most affected areas were cut off by destroyed roads and collapsed bridges and army search-and-rescue teams were being flown in by helicopter.

The governor of the worst-hit province, Compostela Valley, in Mindanao said waves of water and mud came crashing down mountains and swept through schools, town halls and clinics where huddled residents had sought shelter.

The death toll in the province stood at 160. In nearby Davao Oriental province, where Bopha made landfall, 110 people were killed.

The waters came so suddenly and unexpectedly, and the winds were so fierce,” the Compostela Valley governor, Arthur Uy, told Reuters by telephone.

Damage to agriculture and infrastructure in the province was extensive, Uy said.

The village was built in the 11th century. Over the years, it’s been a place for Buddhist prayer, silk worm cultivation, and even gun powder manufacturing. Japan worked with international partners to set up this fire prevention system. They test the system to ensure its function. Very effective way of preserving historic sites from natural hazards.
