LUSI Mud Eruption: Natural or Man-Made Disaster?

LUSI Mud Eruption: Natural or Man-Made Disaster?

Ever since the mud started spewing from the Lumpur Sidoarjo (aka “Lusi”) mud volcano in the subdistrict of Porong, Sidoarjo on East Java Island, Indonesia, on May 29, 2006, an opportunity to study the feature and, fortunately or unfortunately, become embroiled in the political controversy over it opened in the geological community. Newly appointed Assistant Professor Maxwell Rudolph of Portland State University was involved in studies related to this phenomenon during his doctoral years at UC Berkeley ending in 2012, and spoke to GSOC at the June Friday night lecture describing his work.

Recommended Hell's Canyon Book: Tracy Vallier's Islands & Rapids

Our trip guide Keegan Schmidt recommended it as the best book on Hell’s Canyon available....
