A strong and shallow earthquake registered by the USGS as M6.1 hit Tonga at 17:34 UTC on April 19, 2026. The agency is reporting a depth of 36 km (22.4 miles). EMSC is reporting the same magnitude and depth.
A pair of studies published in April 2026 in Science Advances report a consistent decline in observed western-boundary overturning transport across the North Atlantic and suggest that future weakening of the Atlantic Meridional Overturning Circulation (AMOC) could be stronger than standard climate model estimates.
A tornado outbreak struck the Upper Midwest on April 17, 2026, producing multiple EF-2 and EF-3 tornadoes across southeast Minnesota and western Wisconsin, damaging more than 100 homes and injuring at least two people. The strongest tornado, rated EF-3, caused severe structural damage along its path, while the National Weather Service La Crosse office issued a record 26 tornado warnings during the event.
A cluster of underground pipe failures has been detected in San Ramon and surrounding East Bay communities, California, following a sequence of earthquake swarms active in the area since 2025. The incidents include fractured water and sewer lines, often identified only after prolonged leakage periods and abnormal water usage. Experts consider ground movement associated with recent seismic activity as a possible contributing factor, although causation has not been confirmed.
A severe weather outbreak produced multiple tornadoes across the Midwestern United States on April 17, 2026, resulting in structural damage to residential buildings and infrastructure in several states. Preliminary National Weather Service data indicates more than 20 tornado reports, with impacts concentrated in Wisconsin, Illinois, and Minnesota and extending into Missouri, and at least one reported injury.
Authorities raised the volcanic alert level to V1 in the Faial–Pico channel, Azores, Portugal, on April 9, 2026, following low-magnitude seismic activity that began on April 1. The earthquakes occurred along a NE–SW trend west of Madalena to north of Lagido, spanning depths from 20 km (12 miles) to near the surface. The last known eruption at this volcano took place in 1720, with a Volcanic Explosivity Index (VEI) of 2.
The Storm Prediction Center issued a Tornado Watch for a multi-state region of the Upper Midwest at 17:40 UTC (12:40 CDT) on April 17, 2026, citing a highly unstable environment ahead of an advancing cold front. Severe storms are expected to develop through the afternoon and evening, with tornadoes, large hail, and strong wind gusts as primary hazards.
New activity/unrest was reported for 3 volcanoes from April 9 to 15, 2026. During the same period, ongoing activity was reported for 17 volcanoes.
A multi-phase severe weather event is expected to impact the central United States on April 17, 2026, from northern Oklahoma to Wisconsin, with an Enhanced Risk of severe storms in place. Initial supercells may produce strong tornadoes and large hail before transitioning into an organized system capable of widespread damaging winds and localized flash flooding.
Flooding across Michigan, United States, forced evacuations on April 17, 2026, as multiple rivers reached major flood stage following heavy rainfall and rapid snowmelt. Authorities issued emergency declarations in several counties, with evacuations ordered downstream of dams under increased hydrological stress.
