Since the Kīlauea volcano in Hawaii erupted this week, an alert has been issued by NPS regarding its active eruption. Seismic activity has been moderate, but officials are on guard for activity that may potentially cause a tsunami. An official ‘Orange Watch’ has been issued for Kīlauea by USGS, which indicates an active eruption.

“Active lava covers much of the crater floor (an area of approximately 1.5 square km or 370 acres,)” according to USGS.

Long-lasting and frequent volcanic eruptions and consistently powerful earthquakes create a seismically hostile environment within the Hawaiian islands. Considering the seismicity of the islands (Mauna LoaHualālaiMauna KeaKama‘ehuakanaloa, and Haleakalā,) California, Oregon, and Washington are all on alert.

On 7 June 2023, USGS shared a video of the Kīlauea summit eruption in Halema‘uma‘u, Hawaii, and other active volcanoes in Hawaii that may have an impact on the US west coast.

The earthquakes documented below have taken place in a region accustomed to seismic activity, and while their seismicity is being evaluated, there's no need to panic. The reported earthquakes have been documented by the USGS and Hawaiian Volcano Observatory, two of the most credible and globally-recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time.

Magnitude 2.6 Earthquake Struck 4 km West Southwest of Volcano, Hawaii: On 7 June 2023 at 3:36 PM UTC, a magnitude 2.6 earthquake struck Volcano, Hawaii, at a depth of 0.3 km.

Magnitude 2.9 Earthquake Struck 13 km South Southeast of Volcano, Hawaii: On 8 June 2023 at 3:44 PM UTC, a magnitude 2.9 earthquake struck Volcano, Hawaii, at a depth of 3 km.

Residents In New Jersey Urged To Stay Indoors During Spraying Of Toxic Chemicals

Residents in Central New Jersey are being asked to stay indoors on Thursday, 7 September (today,) and Monday, 11 September, due to the release of toxic chemicals in an attempt to mitigate a mosquito crisis in the region. The Mosquito Extermination Commission of Middlesex County announced the use of the chemicals Prallethrin (Sumithrin), Deltamethrin (DeltaGard), Malathion (Fyfanon), and Etofenprox (Zenivex) in the communities of Old Bridge, Monroe, East Brunswick, Helmetta, and Spotswood. The Mosquito Extermination Commission says, “Plan your activities to limit time spent outside during times of possible insecticide treatments. Move your pets, their food, and water dishes inside during application. Also, bring clothing and children’s toys inside. Whenever possible, remain indoors with windows closed and with window air conditioners on non-vent (closed to the outside air) and window fans turned off during spraying. Avoid direct contact with surfaces that are still wet from pesticide spraying. Do not allow children to play in areas that have been sprayed until they have completely dried (approximately one hour.)” Weather permitting, the spraying will be performed between 6:30 PM and midnight. If it rains on 11 September, the county has scheduled the procedure for the following day. The Mosquito Extermination Commission further outlines, “If you must remain outdoors, avoid eye and skin contact with the spray. If you get spray in your eyes or on your skin, immediately flush and rinse with water. Consult your doctor if you think you are experiencing health effects from the spraying. People who suffer from chemical sensitivities or feel spraying may aggravate a preexisting health condition may consult their physician or local health department.” More information regarding plans to spray for mosquitos can be found here:
