Bob Triggs


Bob Triggs was born on the Falkland Islands in 1957. He developed a proclivity for writing when he was ten, but his aspirations were prorogued at eighteen after he moved to live in England. He resettled in London, where the sprawling, densely populated conurbations were a vast departure to the remote, sparsely inhabited, windswept archipelago in the South Atlantic, but he assimilated to city life with surprising ease. He worked in London for nearly two decades before moving to Los Angeles, where he has been living since 1994.

The Andaman Event, which is inspired by the 2004 Indian Ocean earthquake and tsunami, is the exordium to the six-book Tumble series.

Abnormal geological activity in the Bay of Bengal 249 kilometers west of the Andaman & Nicobar Island leads to the discovery of a 200-kilometer rupture in the Australian plate. Because he fears the atypical mechanics in the rift will precipitate a violent seism, Dr. Robert Andrews files an application to fund a scientific expedition to study the incongruity. Gargantuan shockwaves jostle the continental and oceanic tectonics into each other minutes after the approval lands on his desk, triggering a sequential reaction along the convergent boundaries and releasing pent-up stress in subduction zones and fault lines across the globe in a titanic feat straight out of the Archean eon. The abnormal earthquake is the catalyst for an inconceivable disaster that goes unobserved for six months until Mother Nature reveals the ultimate force majeure. The greatest extinction event in history is in progress, and the methodical dismantling of global technological infrastructures and eradication of 8.2 million plants, insect, marine, and animal species—including 7.4 billion humans—will take less than eight weeks. Mankind’s desperate struggle for survival is just beginning.
