Ticks spread the widest variety of diseases that are harmful to humans, including Lyme disease. Here, a University of Tennessee scientist examines a drag cloth used to catch ticks in the field for research purposes.

Lava delta at East Lae‘apuki on the southeast coast of Kīlauea Volcano is about 17 hectares (43 acres). The delta extends about 400 m seaward from the sea cliff and is about 850 m long parallel to the shoreline. The steep sea cliff embayment resulted from collapses of earlier deltas; the collapses undermined and took away parts of the cliff.

Substantial cracks cutting across a lava delta are clear indication that the delta is subsiding as it grows across the unstable pile of interfingering lava flows and fragments built on the steep submarine slope. The larger cracks on this delta are 1-2 m (3-6 ft) wide.
