Roundup of Global Volcanic Activity

Bromo (East Java, Indonesia): Our expedition leader Andi currently on location reported that the volcano's activity has been increased since 4 days ago, with visible activity consisting of mild phreatic explosions and strong steaming. The volcano observatory has been registering continuous tremor as well. Small ballistic ejecta (bombs) can be seen from the rim of the crater.

Nyiragongo (DRCongo): One of the local mountain guides reported that as of 30 May, no more lava flows from the side vent were active and cascading into the main lava lake, although lava bubbling could still be seen at the side vent. Our next group will visit the volcano from 18-21 June and hopefully be able to report the volcano's current activity in more detail.

Kilauea (Hawai'i): Early in the morning of 24 May (at 06:50 local time), a sudden surge in lava supply caused the main lava tube carrying the lava underground away from Pu'u 'O'o to rupture. This resulted in two so-called surface lava breakouts located about 500 m N and NE from the cone, feeding two new large surface lava flows. The lava flows formed broad channels with fast-flowing lava that traveled quickly in opposite directions: towards the northwest and west, and to southeast from their breakout points, respectively. After only a few hours, they both had reached more than 1 km length. Both lava flows currently pose no immediate threat to inhabited areas. The new surface lava flows from the two breakouts north and northeast of Pu'u 'O'o vent on the eastern rift zone remain active. They form broad, branching channels that have been gradually enlarging the two new pahoehoe lava flow fields NW/W and SE of the cone.
