On 25 October 2010 the Twitter account @jalinmerapi was created. The number of followers kept increasing as the condition of Mount Merapi deteriorated. Thanks to the already existing infrastructure, aid in the form of food and logistics was quickly and readily available when the largest eruption occurred on 5 November 2010. JALIN Merapi also manages 5 groups on Facebook with 240 - 250 members in each group. The followers of @jalinmerapi and members of the Jalin Merapi Group are volunteers of JALIN Merapi, government officials and common people. Thousands of messages have passed through all these media.
