![]() I have directed my team to continue to closely monitor the situation in coordination with Turkiye and provide any and all needed assistance,” President Joe Biden said in a tweet. “I am deeply saddened by the loss of life and devastation caused by the earthquake in Turkiye and Syria. “Health facilities are impacted and overwhelmed, and medical personnel in northern Syria working around the clock to respond to the huge numbers of wounded arriving to the facilities,” Sebastien Gay, Doctors Without Borders/Médecins Sans Frontières head in Syria, said in a statement.Ī child watches as people sleep inside a bus following an earthquake in Antakya, Turkey. READ MORE: What to know about the massive earthquake that hit Turkey and Syria ![]() ![]() The quake could be felt as far away as Cairo, but the center was a major fault line in the region of Turkey’s southeastern province of Kahramanmaras, north of Gaziantep and near the border of Syria, whose infrastructure has already been wracked by years of civil war. And those numbers are expected to rise as rescue efforts continue. Thousands of buildings were destroyed in the shaking, trapping people in the rubble thousands of victims have been confirmed dead overall in both countries. Turkey and Syria were rocked early Monday morning by a massive 7.8 magnitude earthquake, followed by several severe aftershocks. Using the observed arrival times from a small number of local earthquakes.Correction: This story incorrectly summarized the current relief efforts by the group Humanity & Inclusion. Obtaining stable estimates of both steep and gradual changes in velocity.įurthermore, we apply our proposed method to real seismic data in central JapanĪnd present the potential of our method for detecting velocity discontinuities Improvements over velocity structures estimated using conventional methods by Synthetic data set to demonstrate that our method provides significant Which has been often used in conventional tomography methods. ![]() The l2-norm to express gradual velocity tendencies in the horizontal direction, We set a horizontal-direction penalty term on the basis of This penalty is intended to represent sharp velocityĬhanges caused by discontinuities by creating a piecewise linear depth profile Of the l2-norms of the second-order differences of the horizontal units in the Utilize a vertical-direction (depth) penalty that takes the form of the l1-sum Vertical and horizontal directions to refine the earthquake tomography. Material boundaries, such as the Conrad and Moho discontinuities and gradualĬhanges in velocity that are associated with pressure and temperatureĭistributions in the crust and mantle. Seismic velocity structure: sharp changes in velocities that correspond to Our approach focuses on theĪbility to better image two common features that are observed in Earth's Structure using arrival time data of direct waves. Regularization technique to determine sharp changes in Earth's seismic velocity Download a PDF of the paper titled Structured regularization based velocity structure estimation in local earthquake tomography for the adaptation to velocity discontinuities, by Yohta Yamanaka and 5 other authors Download PDF Abstract: We propose a local earthquake tomography method that applies a structured
