Rescue effort for the 1883 Krakatoa eruption?
I'm doing a project on the Krakatoa 1883 eruption in geography and need to put in a bit about the rescue effort but can't find any does anyone know anything about it please?

--I found nothing about the rescue effort. The eruption was a complete disaster.Surely some boats tried to evacuate some survivors trapped in the islands.Poison Gas probably thwarted Volcano Rescue Effort --------------------------------------http://volcanoes.suite101.com/article.cfm/krakatoa... combined effects of pyroclastic flows, volcanic ashes and tsunamis had disastrous results in the region. There were no survivors from 3,000 people located at the island of Sebesi, about 13 km (8.1 mi) from Krakatoa. Pyroclastic flows killed around 1,000 people at Ketimbang on the coast of Sumatra some 40 km (25 mi) north from Krakatoa. The official death toll recorded by the Dutch authorities was 36,417, although some sources put the estimate at 120,000 or more. Many settlements were destroyed, including Teluk Betung and Ketimbang in Sumatra, and Sirik and Semarang in Java. The areas of Banten on Java and the Lampung on Sumatra were devastated. There are numerous documented reports of groups of human skeletons floating across the Indian Ocean on rafts of volcanic pumice and washing up on the east coast of Africa, up to a year after the eruption. Some land on Java was never repopulated; it reverted to jungle and is now the Ujung Kulon National Park. http://en.wikipedia.org/wiki/1883_eruption_of_Krak... Ships as far away as South Africa rocked as tsunamis hit them, and the bodies of victims were found floating in the ocean for weeks after the event. The tsunamis which accompanied the eruption are believed to have been caused by gigantic pyroclastic flows entering the sea; each of the four great explosions was accompanied by a massive pyroclastic flow resulting from the gravitational collapse of the eruption column. This caused several cubic kilometers of material to enter the sea, displacing an equally huge volume of seawater. The town of Merak was destroyed by a 46 metre-high tsunami. Some of the pyroclastic flows reached the Sumatran coast as much as 25 miles (40 km) away, having apparently moved across the water on a "cushion" of superheated steam. There are also indications of submarine pyroclastic flows reaching 10 miles (15 km) from the volcano.
A recent documentary film showed tests made by a research team at Kiel University, Germany of pyroclastic flows moving over water. The tests revealed that hot ash traveled over the water on a cloud of superheated steam, continuing to be a pyroclastic flow after crossing water; the heavy matter precipitated out of the flow shortly after initial contact with the water, creating a tsunami due to the precipitate mass.
Smaller waves were recorded on tidal gauges as far away as the English Channel. These occurred too soon to be remnants of the initial tsunamis, and may have been caused by concussive air waves from the eruption. These air waves circled the globe several times and were still detectable using barographs five days later.http://en.wikipedia.org/wiki/1883_eruption_of_Krak...
Geographic effects
In the aftermath of the eruption, it was found that the island of Krakatoa had almost entirely disappeared, except for the southern half of Rakata cone cut off along a vertical cliff, leaving behind a 250-metre (820 ft) deep caldera. Of the northern two-thirds of the island, only a rocky islet named Bootsmansrots ('Bosun's Rock', a fragment of Danan) was left. Also, Poolsche Hoed had disappeared.

they tried to save people and that was the only way they could rescue them, by running as far as they could.
