[00:00.84]D Volcanoes and earthquakes

[00:03.57]are even more dangerous than in the past

[00:06.34]as around half the world's population now

[00:08.95]lives in cities.

[00:10.41]There are more than 500 active

[00:12.79]and semi-active volcanoes,

[00:14.61]about fifty of which erupt each year,

[00:16.96]and more than 500 million people

[00:19.24]now live within the range

[00:21.16]of a volcanic 1 eruption 2.

[00:23.54]An even greater number live at risk,

[00:25.98]in some degree, from earthquakes

[00:28.05]which have taken a toll 3

[00:29.36]of more than 1.6 million

[00:31.45]lives in the last hundred years.

[00:35.82]E All the betting

[00:37.68]from the disaster professionals

[00:39.11]in that things will get worse.

[00:41.53]Professor Hou Ming, of Beijing University,

[00:43.99]is a volcanologist who has been warning

[00:46.34]for years that the world has not seen the worst

[00:48.83]nature can do.

[00:50.43]The worst eruption in human history

[00:52.31]was probably Mt Tambora in 1815,in Indonesia.

[00:57.86]It pumped so much dust into the air

[01:00.18]that it effectively cancelled the following

[01:02.09]summer in Europe and America.

[01:04.50]But geographial evidence shows

[01:06.33]that 73,000 years ago

[01:08.31]there was a much greater eruption.

[01:10.64]"It reduced temperatures by maybe 6C

[01:14.89]in some places and the whole planet

[01:17.28]was plunged 4 into winter for years.

[01:19.83]And there are about two of these events

[01:22.09]every 100,000 years..."
