Interesting going on at Kilauea Volcano, Hawaii Big Island, at the moment.
Extract from USGS Volcanoes
Starting on the afternoon of Monday, April 30, 2018, magma beneath Pu‘u ‘Ō‘ō drained and triggered the collapse of the crater floor. Within hours, earthquakes began migrating east of Pu‘u ‘Ō‘ō, signaling an intrusion of magma along the middle and lower East Rift Zone. As of about noon on Wednesday, May 2, these earthquakes continue along the lower East Rift Zone, with many reports of earthquakes felt by residents in nearby subdivisions. On the map, the orange dashed line marks the approximate area within which most of the earthquakes are located based on automatic earthquake locations and analysis by seismologists. All earthquake locations are preliminary.
Puna residents reported to USGS-Hawaiian Volcano Observatory geologists the recent appearance of ground cracks on a couple of roads in and around Leilani Estates. No steaming or heat were observed to originate from the cracks, and the cracks are currently still small (no more than several inches across). These cracks result from deformation of the ground surface due to the underlying intrusion of magma.
