Описаны особенности реализации, структура и возможности информационных веб-систем, созданных в Институте вулканологии и сейсмологии ДВО РАН, цель которых — обеспечить доступ к большому объему распределенных вулканологических данных для комплексного использования в научных исследованиях. Информационная система VOKKIA предназначена для интеграции и систематизации данных по наземным и подводным вулканам Курило-Камчатского региона и их извержениям, KVERT — для сбора и интеграции данных оперативного мониторинга активности вулканов. Реализованные в информационных системах сервисы поиска и визуализации данных помогают обнаруживать взаимосвязи, закономерности и тенденции изменения вулканогенных процессов во времени.

A large amount of unique scientific data has been collected in the Institute of Volcanology and Seismology (IVS) FEB RAS over the past years of investigations of the Kamchatka and the Kurile Island Arc volcanoes. The distributed nature of information storage makes it difficult to search and effectively use data in scientific research. Actual tasks include the integration of data into thematic information resources, organization of data access on the Internet, as well as the designing of tools for their comprehensive analysis. VOKKIA (Volcanoes of Kurile-Kamchatka Island Arc) and KVERT (Kamchatkan Volcanic Eruption Response Team) information web-systems have been developed in the IVS FEB RAS to solve these tasks. VOKKIA is designed to integrate and systematize the heterogeneous scientific data for the terrestrial volcanoes of Kamchatka, the Kurile Islands and submarine volcanoes of the surrounding seas including data on historical eruptions of active volcanoes. The KVERT system contains brief information about active volcanoes of Kamchatka and the Nothern Kuriles including their hazard. It provides collection and storage of operational data of visual, video, and satellite monitoring of volcanoes as well as automated preparation and sending KVERT releases on volcanic activity. The paper describes the development technology, structure and content of VOKKIA and KVERT. Besides, it describes data search and visualization services and statistical data analysis. The created services allow detecting the relationship, patterns and trends in volcanic processes over time.
