############################# Video Source: www.youtube.com/watch?v=N4-5kLbHY2Y

This film has been produced through the VolFilm Partnership. It describes the hazard that volcanoes generate called pyroclastic flows. Find out what they are, how quickly they move and the properties they have that make them so dangerous and deadly. • VolFilm is funded through the Challenge Fund: a partnership between the World Bank’s Global Facility for Disaster Risk Reduction and Recovery (GFDRR) and the UK Department for International Development (DFID).","styleRuns":[{"startIndex":0,"length":460,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":460,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CIoCELsvGAIiEwjeiJrrkM6JAxXZ6UIFHZPcPLw=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC040LTVrTGJIWTJZGAYyJSIRIgtONC01a0xiSFkyWTAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CIoCELsvGAIiEwjeiJrrkM6JAxXZ6UIFHZPcPLw=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CIkCELovIhMI3oia65DOiQMV2elCBR2T3Dy8"}},"secondaryResults":{"secondaryResults":{"results":[{"lockupViewModel":{"contentImage":{"thumbnailViewModel":{"image":{"sources":[{"url":"https://i.ytimg.com/vi/96IStmZNKSY/hqdefault.jpg?sqp=-oaymwE1CKgBEF5IVfKriqkDKAgBFQAAiEIYAXABwAEG8AEB-AH-CYAC0AWKAgwIABABGFEgWyhlMA8=
